description: “The sky’s the limit” is a phrase used by persons throughout the world to mean possibilities are limitless. For those involved with air transportation we know that the “sky is limited.” As air transportation grows, our airspace has become more and more crowded, challenging aviation professionals to look for new and innovative air traffic control (ATC) procedures and technology to create more efficient use of airspace. The current air traffic control system uses radar along with specified sequencing and separation standards which provide a “safe zone” for each aircraft. However, over the past several years as technology has increased, few enhancements have been made to the air traffic control system to handle the ever increasing air traffic. This lack of technological growth has led to increasingly crowded airspace, more delays, and safety hazards due to the greater number of aircraft in the skies. The summer of 2000 was identified as the worst year for air traffic delays in air transportation history. Delays in 2000 showed a 20% increased over 1999 delays, and a 47% increase over air traffic delays in 1998, showing a need for improved air traffic control technology. In an effort to provide alternatives for air traffic control, Purdue University researchers have been analyzing the European Galileo (GNSS) System. In response to the Air Transportation Association’s Top Ten List of Essential Air Traffic Control Programs, Purdue researchers developed a study to analyze the Galileo system for implementation as the worldwide air traffic control system. The results of the study compare the various global positioning systems in use worldwide and their air traffic control applications; current air traffic control systems worldwide; and the U.S. concerns related to the Galileo system. Based on their findings, Purdue researchers present the advantages and challenges concerning the implementation of Galileo as a worldwide air traffic control system. The paper also addresses how the Galileo worldwide air traffic control system would not only increase the use of airspace and cooperative partnering among nations, but also provide an increased level of safety for the industry.

description: Abstract: We have performed numerical simulations of the electromagnetic hoop stress, σθ , in a REBaCuO disk bulk reinforced by a metal ring during pulsed-field magnetization (PFM) using a solenoid coil, in which the superconducting characteristics of the bulk material were assumed to have realistic J c-B-T ones. The compressive and tensile σθ stresses were applied in the bulk during the ascending and descending stages of PFM, respectively. The time and position dependences of the mechanical stresses were estimated. The possibility of mechanical fracture due to these hoop stresses and the effect of the metal ring reinforcement were discussed.

description: Abstract: Trapped-flux magnets comprising stacked superconducting tape constitute a promising development to increase the power density of electrical machines, whilst at the same time keeping the complexity required in their construction in manageable levels that allow their use in applications such as aircraft propulsion. However, the conditions in which superconducting stacks operate inside an electrical motor differ quite significantly from the materials characterization experiments commonly developed to model their behaviour. This work presents the results of studying the applicability of these devices as magnetic flux source in the rotor of synchronous machines considering the influence of whole magnetic circuit. Several aspects are assessed, such as flux harmonics, magnetization, losses and demagnetization. Analytical expressions, which provide limited accuracy but allow fast calculations, are used for this purpose. The results illustrate the different trade-offs that arise during the design of a synchronous electric motor using trapped-flux magnets.

description: Iridomyrmex bicknelli luteus Forel, species inquirenda
 Iridomyrmex bicknelli lutea Forel, 1915: 77.
 Types. Holotype worker from Kimberley district, Western Australia (not located during this study, apparently lost).
 Comments: Treatment of I. bicknelli luteus is complicated by the apparent loss of the holotype combined with an original description consisting of the single sentence (translated from German) “Completely bright red-yellow, otherwise completely like [bicknelli]; the head in the back somewhat less convex”. Unfortunately, we are unaware of any species that is similar to I. bicknelli but is bright red-yellow and occurs in northern Western Australia. Iridomyrmex bicknelli itself is brown to black in colour and even callow or faded workers would not be described as bright red-yellow, normally being pale yellow. The description is suggestive of the pale form of I. agilis, but this taxon does not occur near the reported type locality of I. luteus. A more likely candidate would be the bright-red, narrow headed form of I. minor, a very common species in northern Western Australia which has a less convex posterior margin of the head when compared to I. bicknelli. However, without the type and with little more than a vague one line description it is impossible to determine, with any confidence, the true identity of this taxon. We therefore treat this name as species inquirenda within Iridomyrmex until the lost holotype can be located.

description: The immersion-analogue of Hadwiger's Conjecture states that every graph $G$ contains an immersion of $K_{χ(G)}$. This conjecture has been recently strengthened in the following way: every graph $G$ contains a totally odd immersion of $K_{χ(G)}$. We prove this stronger conjecture for line graphs of constant-multiplicity multigraphs, thus extending a result of Guyer and McDonald.

description: In the United States as in many nations, there are often differences between the travel patterns of men and women with regards to the differences in travel. Traditionally, women make shorter work trips, make greater use of public transit, make more trips for the purpose of serving another person's travel needs, and drive far fewer miles per year than men. These differences in travel are delineated by the separate social responsibilities of men and women. However, in the past few decades, women have been participating more in the labor force. In addition, women still retain their family obligations as nurturers, shoppers, and homemakers. Given the changes in the transit patterns of women in recent decades, women’s travel patterns still differed substantially from those of men. In fact, these emerging trends from transit patterns of women, their actual vehicle miles traveled (VMT) are starting to increase and may surpass the VMT of men. Additionally, it is speculated by transportation planners and policy-makers that the VMT of women will surpass the VMT of men in the future. In the past, transportation studies have not been particularly oriented to women’s’ travel issues despite the presence of the data and statistical methodologies. On the other hand, surveys such as the National Household Transportation Survey (NHTS) can be used to understand trends in women's travel patterns, which are often attributed to changes in labor force participation, household structure, and attitudes. This paper will analyze the differences in the vehicle miles traveled (VMT) between men and women using nonparametric methods using the data from the NHTS data as prepared by the Bureau of Transportation Statistics (BTS) in the U.S. Department of Transportation. Moreover, the examination of the relationship of VMT and other household variables would be estimated in a flexible way which cannot be assessed using parametric modeling methods.

description: While statistical and artificial intelligence methods such as Artificial Neural Networks (ANN) have been used successfully to classify organizations in terms of solvency or insolvency, they are limited in degree of generalization either by requiring linearly separable variables, lack of knowledge of how a conclusion is reached, or lack of a consistent approach for dealing with local optimal solution whether maximum or minimum. This research explores the use of a method that has the ability of the ANN method to deal with linearly inseparable variables and incomplete, noisy data; and resolves the problem of falling into a local optimum in searching the problems space. The paper applies a genetic algorithm to a sample of U.S. airlines and utilizes financial data from carrier income statements and balance sheets and ratios calculated from this data to assess air carrier solvency.
An analytical model for the history of cosmic star formation

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use simple analytic reasoning to identify physical processes that drive the evolution of the cosmic star formation density in cold dark matter universes. Based on our analysis, we formulate a model to characterise the redshift dependence of the star formation history and compare it to results obtained from a set of hydrodynamic simulations which include star formation and feedback. At early times, densities are sufficiently high and cooling times sufficiently short that abundant quantities of star-forming gas are present in all dark matter halos that can cool by atomic processes. Consequently, the star formation density generically rises exponentially as z decreases, independent of the details of the physical model for star formation, but dependent on the normalisation and shape of the cosmological power spectrum. This part of the evolution is dominated by gravitationally driven growth of the halo mass function. At low redshifts, densities decline as the universe expands to the point that cooling is inhibited, limiting the amount of star-forming gas available. We find that in this regime the star formation rate scales approximately in proportion to the cooling rate within halos. We derive analytic expressions for the full star formation history and show that they match our simulation results to better than ~10%. Using various approximations, we reduce the expressions to a simple analytic fitting function that can be used to compute global cosmological quantities that are directly related to the star formation history. As examples, we consider the integrated stellar density, the supernova and gamma-ray burst rates observable on Earth, the metal enrichment history of the Universe, and the density of compact objects.

description: The present study was an attempt to analyze the farmers’ perception about causes and remedies of Monga in some selected areas of Lalmonirhat district of Bangladesh. In order to achieve the objectives, survey was conducted in three villages and one Char area in Hatibandha upazila of Lalmonirhat district. In total 90 samples were purposively taken of which 45 were from Char area, 25 from rural area, and 20 from urban area. The family size of the respondents revealed that medium family domination in Char area (the poorest area) is an indication of the consciousness of the poor people about population problem. Monga stricken people in terms of less consumption were higher in Char and rural areas compared to urban area. Lack of cultivable land, natural calamities, nonavailability of working facilities at non-agricultural sector, lack of working facilities at agricultural sector due to natural calamities and lack of credit availability and high interest rate were opined by the researcher as their causes of Monga. On the other hand, beef fattening, petty business, plant nursery and poultry farming were addressed as the mitigating activities of Monga undertaken by NGOs. old-age allowance, Hundred-days job scheme and Vulnerable Group Development (VGD) programme were observed as Monga mitigating activities undertaken by GOs in the study area. The difference between the performance of GO and NGO in Monga mitigation was wider in Char area than that of in rural and urban areas. The higher performance of NGOs was due to their better identification, selection and supervision strategy with perfect information. Drawbacks like, corruption, lack of proper management, lack of adequate financial support, etc., might be responsible for the poor performance of GO mitigating activities of Monga in the study area.

description: Tapinoma latifrons (Karavaiev), comb. nov.
 Iridomyrmex latifrons Karavaiev, 1933: 305, fig. 1.
 Types. Holotype worker from Bantam, Java, Indonesia (UASK, examined).
 Comments. Iridomyrmex latifrons Karavaiev is here transferred to the genus Tapinoma. The holotype specimen does not possess a petiolar node (this can be ascertained, despite the fact that the petiole is partially hidden by the collapsed gaster). The absence of a node requires the specimen to be removed from the genus Iridomyrmex, whose taxa all possess a node or a nodiform ridge. The holotype specimen can also be excluded from the dolichoderine genus Technomyrmex due to only four gastral tergites being visible in dorsal view (five tergites are visible in Technomyrmex). Finally, the insertion of the posterior sector of the clypeus between the frontal carinae is a broad arc, a feature that separates Tapinoma species from the Australian genus Doleromyrma, in which the suture demarcating the posterior clypeal border is more narrowly rectangular in appearance (Heterick, 2009). All other visible features of the worker are consistent with the genus Tapinoma as characterised by Bolton (1994).

description: In black-box optimization, it is essential to understand why an algorithm instance works on a set of problem instances while failing on others and provide explanations of its behavior. We propose a methodology for formulating an algorithm instance footprint that consists of a set of problem instances that are easy to be solved and a set of problem instances that are difficult to be solved, for an algorithm instance. This behavior of the algorithm instance is further linked to the landscape properties of the problem instances to provide explanations of which properties make some problem instances easy or challenging. The proposed methodology uses meta-representations that embed the landscape properties of the problem instances and the performance of the algorithm into the same vector space. These meta-representations are obtained by training a supervised machine learning regression model for algorithm performance prediction and applying model explainability techniques to assess the importance of the landscape features to the performance predictions. Next, deterministic clustering of the meta-representations demonstrates that using them captures algorithm performance across the space and detects regions of poor and good algorithm performance, together with an explanation of which landscape properties are leading to it.

description: We propose the Hirota bilinearization of the Fokas-Lenells derivative nonlinear Schrodinger equation with a non-vanishing background. The bilinear method is applied using an auxilary function to obtain the dark one soliton solution, dark two soliton solution and eventually the scheme for obtaining dark N soliton solutions. The use of auxilary function in bilinearization makes the method simpler than the ones reported earlier. Later, we have introduced a Lax pair for this integrable equation and using a transformation we have shown that this system is gauge equivalent to a spin system, namely the Landau-Lifshitz equation.

description: Abstract: This work presents results of investigation of crossed-field demagnetization in 2G high temperature superconducting stacks at temperatures in the range of 77 - 20 K and in a variable frequency, corresponding to the particular rotor application. We propose a method to reduce the demagnetization rate for a given stack configuration necessary for the superconducting rotor operating at a cryogenic temperature. This technique involves 3-D wrapping the stack of tapes with perpendicular layers of similar superconducting properties. Previous ‘proof of concept’ studies documented some improvements in flux demagnetisation reduction for basic configuration. In the present study a more advanced approach based on magnetic flux shielding is adopted. The presented results provide an important contribution to development for design solutions that aim to increase the operational time before remagnetisation of the stacks would be required.

description: Abstract: Stacks of HTS superconductors can be magnetized and used as a surface mounted magnet for electrical machines. Pulse field magnetization is considered as a practical method; however, the amplitude of the pulse can be limited in an electrical motor which results in an under-saturated stack with the superconducting currents penetrating only a part of it making the magnetization less efficient. A solution to this problem could be sectioning the stack along its width enabling effective penetration of the superconducting currents. In this paper we investigate the effect of sectioning of HTS surface mounted stacks on the efficiency of pulse magnetization method in trapping the flux using low pulsing field. It is shown that the sectioning of wide stacks into several narrower parts results in a higher trapped flux at low pulses. Experimental measurements are performed on a lab-scale motor to validate the theoretical analysis.

description: Abstract: The heat is generated inside the stack of superconducting tapes mounted on the surface of the electrical machine rotor during its operation and magnetization. Cooling of such stack presents challenges because of the layered structure of both tape, and stack. Moreover, the tapes should be electrically isolated to minimize the AC losses, that assumes gluing them, rather than soldering. The calculations consider a conductive heat dissipation also through the rotor iron. Results show that: liquid nitrogen provides an effective cooling; the temperature of the stack shows complex distribution patterns with the gaseous coolant. Additional preventive measures were analyzed to keep the stack operational in vacuum conditions.

 Comments. This is an impression fossil of a queen. There is so little morphological detail available that rigorous generic placement is nearly impossible. As such, and following Shattuck (1992a), it is here left in Iridomyrmex but this placement is little more than speculation and it is considered incertae sedis in the genus.

description: The study examines the impact of the rice-cum-fish culture and the rice-mono culture on the rural households at Muktaghachha upazila of Mymensingh district in Bangladesh. Data were collected from 100 farmers of five villages following stratified random sampling technique. Activity budgets were prepared and comparisons were made through the tabular and statistical analyses. Both the rice-cum-fish culture and the rice-mono culture were profitable business for the farmers. However, farmers earned about 3 times higher profits from the rice-cum-fish culture than the ricemono culture. Per hectare net returns of the rice-cum-fish culture and the rice-mono culture were Tk. 15345.00 and 5389.50, respectively. Rice yield, fish consumption, total cost were increased by 11.4, 14.5 and 48.9 percent respectively while human labour employment was increased by 9.4 percent in the integrated rice-cum-fish culture compared to the rice-mono culture. The study clearly hints that the rice-cum-fish culture provides greater scope for higher returns and employment opportunities of human labour than the rice-mono culture.

description: The intention of this thesis is to investigate the circumstances and background surrounding the early development and deployment of the Special Operations Executive (SOE), Britain's clandestine secret service created by Winston Churchill in 1940 to 'set Europe ablaze.' It will examine the climate in which SOE was created, the feasibility of the tasks it was expected to perform and the relationships it established with Churchill, the Cabinet Office, the Chiefs of Staff, the Foreign Office, the Admiralty and Army, the Secret Intelligence Service (SIS) and Combined Operations. It will examine how these organisations succeeded or failed to work towards a common wartime objective. The focus of the thesis is concerned primarily with the political moves and counter-moves in London that dominated the early years of SOE's six year existence. It will concentrate therefore upon 1940-1942, the critical early years before planning for the Second Front 'militarised' SOE's clandestine role. There is thus little reference to SOE in The Balkans, in Holland or the Middle East or to the actual deployment and modus operandi of SOE agents in the field. Their stories of courage and betrayal, of penetration, capture or evasion are mentioned only in so far as they illuminate the struggle to establish a wider SOE credibility in London. The single exception to this is Operation Frankton, the 'Cockleshell Heroes' raid on Bordeaux shipping in December 1942. The planning, execution and result of this raid were determined by Combined Operations' relationship with SOE and led to an outcome that was shaped by SOE's sense of secrecy, rivalry and political encirclement. This thesis will attempt to unravel those critical and complex relationships.

 Comments. Type material of this taxon could not be located during this study. However, the figure provided by Emery (1887, fig. 26) matches specimens of Anonychomyrma held in ANIC and is unlike species of Iridomyrmex known from the vicinity of this species’ type locality. In this species the pronotum is relatively high and is set off from the mesonotum by an angle, and the propodeum is high and dome-like. This configuration differs from known Indonesian species of Iridomyrmex. Therefore, this name is treated as belonging to Anonychomyrma rather than Iridomyrmex.

description: Supply Chain Management (SCM) is an integral approach of management where lots of beneficiaries work together with their professional interest. Potatoes supply chain like other agricultural products in developed country like the United Kingdom included some important beneficiaries. Interests are not same due to the nature of the professional activity. In distribution systems in developed country always have problems to organise all beneficiaries. Some beneficiaries are discriminated some are not their status as profitable either company or sole trader. In the study, potato farmers of Northern Ireland produce potatoes and these potatoes supposed to be distributed directly to the consumers. As the work in the capitalist society divided in many ways with profit motive, therefore there were many intermediaries between producers and consumers who worked for distributing NI potato to the consumers. They were related together with their own interest and goal. One beneficiary was not thinking about another beneficiary with any kind of interest sacrifice. Finally farmers who were the main producers became discriminated with the price. This is the main problem found in the study. Consumers also have no intention to know the life of farmers. If farmers’ society is not survived in sustainable development way then the potatoes will not be cultivated. Therefore in potatoes farming everybody in the society needs to make their attention for the right of the potatoes farmers of NI.

description: Agent-based simulations have been used in modeling transportation systems for traffic management and passenger flows. In this work, we hope to shed light on the complex factors that influence transportation mode decisions within developing countries, using Colombia as a case study. We model an ecosystem of human agents that decide at each time step on the mode of transportation they would take to work. Their decision is based on a combination of their personal satisfaction with the journey they had just taken, which is evaluated across a personal vector of needs, the information they crowdsource from their prevailing social network, and their personal uncertainty about the experience of trying a new transport solution. We simulate different network structures to analyze the social influence for different decision-makers. We find that in low/medium connected groups inquisitive people actively change modes cyclically over the years while imitators cluster rapidly and change less frequently.

subject: Ways of reducing in-store losses

description: The study aimed at assessing the in-store losses of rice caused by biotic and abiotic factors in the storage structures/containers at farmers’ level. The farmers’ suggested ways of reducing in-store losses of rice are also discussed. A total of 96 villages covering 26 Upazilas under 14 civil districts across all the divisions of the country were selected for present investigation. The districts were put under five different regions to capture the dimensions of study. In all, 1360 samples of Aus, Aman and Boro rice farmers were selected randomly and purposively from the study areas and put into marginal, small, medium and large farm category based on their land ownerships. Data were collected through pre-tested questionnaires. Different traditional rice storage structures/containers like Dole, Berh, Inside-house Gola, Outside-house Gola, Steel/Plastic drums, Motka, Gunny bag and Plastic/Polythene bags were commonly used by farmers in the study areas. The storage time of rice varied from 3.05 to 7.24 months irrespective of rice, farm and region with the overall average being 5.5 months. Significant losses in stored rice occurred through the activities of both biotic and abiotic factors. The average in-store losses occurred for Aus, Aman and Boro rice were respectively 3.68, 3.80 and 4.12% with the aggregated average being 3.92%. The average in-store losses of rice in large, medium, small and marginal farmers were 4.48, 3.92, 4.0 and 3.59% respectively. The in-store losses occurred in regions 1, 2, 3, 4 and 5 were 3.31, 5.23, 3.62, 4.44 and 3.25% respectively. The farmers suggested a number of ways for reducing in-store losses of rice including training on capacity building and awareness for safe storage, credit for constructing durable storage structure, construction of common storage structures at village/union level, preventive measures against biotic and abiotic factors, supplying farmers with durable storage containers and keeping them well ahead informed about the natural calamities.

description: The number of times that we can access a system to extract information via quantum metrology is always finite, and possibly small, and realistic amounts of prior knowledge tend to be moderate. Thus theoretical consistency demands a methodology that departs from asymptotic approximations and restricted parameter locations, while practical convenience requires that it is also flexible and easy to use in applications with limited data. We submit that this methodology can and should be built on a Bayesian framework, and in this thesis we propose, construct, explore and exploit a new non-asymptotic quantum metrology. First we show the consistency of taking those solutions that are optimal in the asymptotic regime of many trials as a guide to calculate a Bayesian measure of uncertainty. This provides an approximate but useful way of studying the non-asymptotic regime whenever an exact optimisation is intractable, and it avoids the non-physical results that can arise when only the asymptotic theory is used. Secondly, we construct a new non-asymptotic Bayesian bound without relying on the previous approximation by first selecting a single-shot optimal quantum strategy, and then simulating a sequence of repetitions of this scheme. These methods are then applied to a single-parameter Mach-Zehnder interferometer, and to multi-parameter qubit and optical sensing networks. Our results provide a detailed characterisation of how the interplay between prior information, correlations and a limited amount of data affects the performance of quantum metrology protocols, which opens the door to a vast set of unexplored possibilities to enhance non-asymptotic schemes. Finally, we provide practical researchers with a numerical toolbox for Bayesian metrology, while theoretical workers will benefit from the broader and more fundamental perspective that arises from the unified character of our methodology.

description: The purpose of this paper is to discuss the relationship between commutative and non-commutative integrability of Hamiltonian systems and to construct new examples of integrable geodesic flows on Riemannian manifolds. In particular, we prove that the geodesic flow of the bi-invariant metric on any bi-quotient of a compact Lie group is integrable in non-commutative sense by means of polynomial integrals, and therefore, in classical commutative sense by means of $C^\infty$--smooth integrals.

description: The problem of describing optical turbulent structures, arising in resonant media with high Fresnel numbers, is reviewed. The consideration is based on the probabilistic approach to pattern selection, ascribing a probability distribution of patterns to systems with multiple possible structures. The most probable structure corresponds to the minimal expansion exponent, or to the minimal expansion rate, characterizing the phase-space expansion of a dynamical system. Turbulent photon filamentation is studied. The most probable filament radius and the number of filaments are found, being in good agreement with experiment.

description: This study was conducted with the development of instant fish soup mix and finding out the effect of fish powder on it. Ingredients of soup mix were cooked and dried up to desired moisture content. The drying or dehydration was done by using a mechanical dryer (Cabinet dryer) at constant air flow rate and constant temperature with varying thicknesses. After drying the dried products were ground to make powder. These were then mixed with desired composition. Here fish powder was varied in composition in different samples and it was 5%, 10% and 15% in Mix-1, Mix-2 and Mix-3 respectively. For preparing soup mix was reconstituted with boiled water. The result of organoleptic test was determined by ANOVA and DMRT analysis to find out the best sample. (Mix-2) was adjudged to be the best by the panelists using 1-9 hedonic scale and ranked as “like very much” securing score 8.0 which containing 10% fish power.

description: Image resolution of quantum imaging with undetected photons is governed by the spatial correlations existing between the photons of a photon pair that has been generated in a nonlinear process. These correlations allow for obtaining an image of an object with light that never interacted with that object. Depending on the imaging configuration, either position or momentum correlations are exploited. We hereby experimentally analyse how the crystal length and pump waist affect the image resolution when using position correlations of photons that have been generated via spontaneous parametric down conversion in a nonlinear interferometer. Our results support existing theoretical models for the dependency of the resolution on the crystal length. In addition, we probe the resolution of our quantum imaging scheme for varying pump waists over one order of magnitude. This analysis reveals the intricate dependency of the resolution on the strength of the correlations within the biphoton states for parameter combinations in which the crystal lengths are much larger than the involved photon wavelengths. We extend the existing models in this parameter regime to properly take nontrivial effects of finite pump waists into account and demonstrate that they match the experimental results.

description: A new type of metal-dielectric composites has been proposed that is characterised by a resonance-like behaviour of the effective permeability in the infrared and visible spectral ranges. This material can be referred to as optomagnetic medium. The analytical formalism developed is based on solving the scattering problem for considered inclusions with impedance boundary condition, which yields the current and charge distributions within the inclusions. The presence of the effective magnetic permeability and its resonant properties lead to novel optical effects and open new possible applications.

Years of potential life lost in schizophrenia and mental health: changes in mortality due to non-genetic healthcare and lifestyle factors
Creators: name: Cignarella, Ryan James

description: Schizophrenia is a devastating and complex disorder, which impacts normal brain functions, creating mental disarray, including hallucinations, delusions, cognitive deficits, and paranoia. This disorder, while debilitating to the quality of life for the patient, also presents confounding implications for the application of a coherent body of care from medical professionals because of the complex interaction between the psychiatric and psychological affectations of this disorder and the contemporaneous illnesses that additionally threaten patients’ health. Failure to diagnose and effectively treat the comorbid conditions represents a barrier to successful care for these patients. The interaction between illnesses which exist simultaneously in one patient affects the prognosis, complicates treatment and outcomes, and impacts the cost of care. This study juxtaposes historical findings and contemporary research as they pertain to the multitude of simultaneous conditions affecting schizophrenia patients. While oftentimes addressed as independently occurring in earlier studies, schizophrenic comorbid afflictions are correlated to drug interactions, patient self-medication, and lifestyle in contemporary research, signaling increased opportunities for intervention from medical professionals. Further, a heretofore untapped prospect exists to develop a therapeutic approach based on the knowledge that one such comorbid factor – schizophrenic patients’ nicotine dependence, which could indicate an undeveloped treatment option. That is, whether the amplified use of nicotine by schizophrenia patients highlights an opportunity to address sensory insufficiencies in these patients by formulating substitute medications which can concomitantly improve sensory processing deficits, stimulating the release of dopamine as nicotine does, without inhaling the many harmful ingredients present in tobacco which are well-known to cause coronary heart disease, circulatory problems and stroke, and lung ailments, including emphysema and chronic bronchitis. An argument for pursuing this opportunity is also discussed herein.
