Interfaz de Bajo Costo Usando un Puerto Paralelo y Visual Basic
Escobar, Rogelio;Lattal, Kennon A.;
Revista mexicana de análisis de la conducta , 2010, DOI: 10.5514/rmac.v36.i3.01
Abstract: the design of a low-cost interface is described that uses the parallel port of a pc to control experiments that require from 1 to 8 outputs in combination with 1 to 4 inputs using the programming language visual basic? 2008 express edition that is freely distributed. this interface allows for controlling response-input consoles and experimental chambers that can be used in experiments with humans and nonhuman animals using only a computer. to facilitate the application of the interface in experiments on behavior analysis, the use of micro switches and photobeam sensors for recording responses as well as the use of devices controlled via micro relays is described.
Producing the Rigorous Design Case
Kennon M. Smith
International Journal of Designs for Learning , 2010,
Abstract: Producing a rigorous design case, and producing a case that holds utility for designers, are not always one and the same act. The differences between rigor and utility in design cases are discussed in this article, as well as the position of the design case in the broader realm of naturalistic research. Drawing from naturalistic and action research, possible standards of rigor for cases emerge. These are presented and related to the representation of design knowledge. The article then presents issues observed among authors of traditional research in producing design cases of rigor.
Providing the Scientific Backbone for Positive Psychology: A Multi-Level Conception of Human Thriving
Kennon M. Sheldon
Psychological Topics , 2009,
Abstract: This article begins with a consideration of what is missing in positive psychology – namely, an integrative framework within which to view the entire person, especially as nested within more-or-less supportive social contexts and cultures. Thus, I presented a multi-level hierarchical framework for considering and explaining human behavior, arguing that all levels of the framework are necessary for complete exposition. From this point of view, personality processes cannot be reduced to "mere" cognitive processes; there are trans-cognitive rules and laws operating at this higher level. I also considered a four level sub-framework within the personality level of analysis, consisting of organismic needs/characteristics, traits/dispositions, goals/intentions, and self/self-narratives. I contended that each of these spheres of the person operates via unique rules and regularities, processes that cannot be reduced to lower levels of analysis (such as biological, neurological, and cognitive levels of analysis). Finally, I described some recent research that simultaneously examines factors at multiple levels of the SLOPIC model, showing that each has influence for predicting SWB, and moreover, that all of these effects are mediated by basic need satisfaction. Hopefully this line of research will prove useful for other positive psychologists seeking "the big picture" on human flourishing.
Preliminary Investigations into the Development of Textile Based Temperature Sensor for Healthcare Applications
Muhammad Dawood Husain,Richard Kennon
Fibers , 2013, DOI: 10.3390/fib1010002
Abstract: Human body temperature is an important sign of physical condition in terms of comfort, heat or cold stresses, and of performance. This paper presents the preliminary investigation into the design, manufacturing and testing of the textile based temperature sensor. This sensing fabric may be employed to measure the temperature of the human body on a continuous basis over extensive periods of time, outside the clinical environment. The sensing fabric was manufactured on an industrial scale flat-bed knitting machine by laying-in the sensing element (in the form of fine metal wire) into the double layer knitted structure. The operational principle of the sensing fabric is based on the inherent tendency of metal wire to change in its electrical resistance because of the change in its temperature. An experimental resistance-temperature relationship showed promising validation in comparison with their modeled counterparts.

Tourismos : an International Multidisciplinary Journal of Tourism , 2012,
Abstract: Indians increasingly travel to foreign countries in a large number every year. To date, there are no studies focusing on this group of tourists. This study thus investigates the Indian tourists’ motivation and perception of Bangkok, Thailand. The study shows that both push and pull factors stimulate these Indians to travel. The most important motivations are to have fun, followed by to enjoy the beautiful environment, scenery, and beaches. Based on 20 motivations, four core typologies of Indian tourists are found: Novelty Seeking, Stress Busting/Fun, Achievement, and Family Oriented/Education. Family and/or friends and the Internet are perceived by Indian tourists as important sources in trip decision making.
Textile-Based Weft Knitted Strain Sensors: Effect of Fabric Parameters on Sensor Properties
Ozgur Atalay,William Richard Kennon,Muhammad Dawood Husain
Sensors , 2013, DOI: 10.3390/s130811114
Abstract: The design and development of textile-based strain sensors has been a focus of research and many investigators have studied this subject. This paper presents a new textile-based strain sensor design and shows the effect of base fabric parameters on its sensing properties. Sensing fabric could be used to measure articulations of the human body in the real environment. The strain sensing fabric was produced by using electronic flat-bed knitting technology; the base fabric was produced with elastomeric yarns in an interlock arrangement and a conductive yarn was embedded in this substrate to create a series of single loop structures. Experimental results show that there is a strong relationship between base fabric parameters and sensor properties.
Case reports describing treatments in the emergency medicine literature: missing and misleading information
Tiffany P Richason, Stephen M Paulson, Steven R Lowenstein, Kennon J Heard
BMC Emergency Medicine , 2009, DOI: 10.1186/1471-227x-9-10
Abstract: In this study we sought to determine the proportion of treatment-related case reports that adequately reported information about the patient, disease, interventions, co-interventions, outcomes and other critical information.We identified CRs published in 4 emergency medicine journals in 2000–2005 and categorized them according to their purpose (disease description, overdose or adverse drug reactioin, diagnostic test or treatment effect). Treatment-related CRs were reviewed for the presence or absence of 11 reporting elements.All told, 1,316 CRs were identified; of these, 85 (6.5%; 95CI = 66, 84) were about medical or surgical treatments. Most contained adequate descriptions of the patient (99%; 95CI = 95, 100), the stage and severity of the patient's disease (88%; 95CI = 79, 93), the intervention (80%; 95CI = 70, 87) and the outcomes of treatment (90%; 95CI = 82, 95). Fewer CRs reported the patient's co-morbidities (45%; 95CI = 35, 56), concurrent medications (30%; 95CI = 21, 40) or co-interventions (57%; 95CI = 46, 67) or mentioned any possible treatment side-effects (33%; 95CI = 24, 44). Only 37% (95CI = 19, 38) discussed alternative explanations for favorable outcomes. Generalizability of treatment effects to other patients was mentioned in only 29% (95CI = 20, 39). Just 2 CRs (2.3%; 95CI = 1, 8) reported a 'denominator" (number of patients subjected to the same intervention, whether or not successful.Treatment-related CRs in emergency medicine journals often omit critical details about treatments, co-interventions, outcomes, generalizability, causality and denominators. As a result, the information may be misleading to providers, and the clinical applications may be detrimental to patient care.An air of serving the common good clings to the process of reporting as general information the results of one's own extensive experience. [1]For almost 200 years, clinical case reports have been a prominent feature of medical journalism. Penicillin, ether and insulin were
Acetaminophen-cysteine adducts during therapeutic dosing and following overdose
Kennon J Heard, Jody L Green, Laura P James, Bryan S Judge, Liza Zolot, Sean Rhyee, Richard C Dart
BMC Gastroenterology , 2011, DOI: 10.1186/1471-230x-11-20
Abstract: Samples were collected during three clinical trials in which subjects received 4 g/day of acetaminophen and during an observational study of acetaminophen overdose patients. Trial 1 consisted of non-drinkers who received APAP for 10 days, Trial 2 consisted of moderate drinkers dosed for 10 days and Trial 3 included subjects who chronically abuse alcohol dosed for 5 days. Patients in the observational study were categorized by type of acetaminophen exposure (single or repeated). Serum APAP-CYS was measured using high pressure liquid chromatography with electrochemical detection.Trial 1 included 144 samples from 24 subjects; Trial 2 included 182 samples from 91 subjects and Trial 3 included 200 samples from 40 subjects. In addition, we collected samples from 19 subjects with acute acetaminophen ingestion, 7 subjects with repeated acetaminophen exposure and 4 subjects who ingested another hepatotoxin. The mean (SD) peak APAP-CYS concentrations for the Trials were: Trial 1- 0.4 (0.20) nmol/ml, Trial 2- 0.1 (0.09) nmol/ml and Trial 3- 0.3 (0.12) nmol/ml. APAP-CYS concentrations varied substantially among the patients with acetaminophen toxicity (0.10 to 27.3 nmol/ml). No subject had detectable APAP-CYS following exposure to a non-acetaminophen hepatotoxin.Lower concentrations of APAP-CYS are detectable after exposure to therapeutic doses of acetaminophen and higher concentrations are detected after acute acetaminophen overdose and in patients with acetaminophen toxicity following repeated exposure.Acetaminophen toxicity is a major cause of acute liver failure in the United States. While many cases have a clear history of acetaminophen exposure, there are a substantial number of cases in which the cause of liver injury is not clear. As serum acetaminophen concentrations may be undetectable by the time the patient has acute liver failure, there is a need for a biomarker with a longer detection time.The metabolism of acetaminophen by CYP2E1 forms N-acetyl-p-benzoquinone imi
Overuse of non-prescription analgesics by dental clinic patients
Kennon J Heard, Nicole L Ries, Richard C Dart, Gregory M Bogdan, Richard D Zallen, Frank Daly
BMC Oral Health , 2008, DOI: 10.1186/1472-6831-8-33
Abstract: All adult patients presenting to an urban dental clinic during a two-week period in January and February of 2001 were approached to participate in this research project. Trained research assistants using a standardized questionnaire interviewed patients. Patient demographics and the NPA usage over the 3 days preceding the office visit were recorded. We defined a supra-therapeutic dose as any dose greater than the total recommended daily dose stated on package labeling.We approached 194 patients and 127 participated. The mean age of participants was 35.5 years, 52% were male. Analgesic use preceding the visit was reported by 99 of 127 patients, and most (81/99) used a NPA exclusively. Fifty-four percent of NPA users were taking more than one NPA. NPA users reported using ibuprofen (37%), acetaminophen (27%), acetaminophen/aspirin combination product (8%), naproxen (8%), and aspirin (4%). Sixteen patients reported supra-therapeutic use of one or more NPA (some ingested multiple products): ibuprofen (14), acetaminophen (3), and naproxen (5).NPA use was common in patients presenting to a dental clinic. A significant minority of patients reported excessive dosing of NPA. Ibuprofen was the most frequently misused product, followed by naproxen and acetaminophen. Though mostly aware of the potential toxicity of NPA, many patients used supra-therapeutic dosages.Pain is a common complaint among patients presenting for emergency care at a dental clinic. Non-prescription analgesic pain relievers are commonly used by patients with dental pain. They decrease pain when administered after dental extractions [1-3] and when administered prior to dental surgery [4]. There are fewer studies evaluating the utility of these products for dental pain not related to dental procedures. Korberly studied patients presenting to a dental clinic for acute pain and found that both acetaminophen (1 g) and aspirin (1 g) decreased pain relative to placebo.[5] These studies all suggest that non-prescr
The Spread of Infectious Disease on Network Using Neutrosophic Algebraic Structure  [PDF]
A. Zubairu, A. A. Ibrahim
Open Journal of Discrete Mathematics (OJDM) , 2017, DOI: 10.4236/ojdm.2017.72009
Abstract: Network theory and its associated techniques has tremendous impact in various discipline and research, from computer, engineering, architecture, humanities, social science to system biology. However in recent years epidemiology can be said to utilizes these potentials of network theory more than any other discipline. Graph which has been considered as the processor in network theory has a close relationship with epidemiology that dated as far back as early 1900 [1]. This is because the earliest models of infectious disease transfer were in a form of compartment which defines a graph even though adequate knowledge of mathematical computation and mechanistic behavior is scarce. This paper introduces a new type of disease propagation on network utilizing the potentials of neutrosophic algebraic group structures and graph theory.
