Psychodynamic Theory in Early Childhood Education: A Look at the Contributions of Anna Freud, Melanie Klein, Krik H. Erikson, Susan Isaacs, Bruno Bettelheim, E.C.M. Frijling-Schreuder and Margaret Ribble
Dean, Ann V.
College Forum , 1986,
Abstract: In this paper I will examine the implications of psychodynamic theory for teaching and learning in early childhood education.The indivudual pioneering efforts of Anna Freud and Melanie Klein in understanding childhood neurosis and in developing child analysis and "play therapy" will be described and compared. Anna Freud's strong early convictions of the need for a psychoanalytic pedagogy and later disillusionment will be discussed.Basic psychoanalytic terms such as "the unconscious", "Id, Ego, Superego", "transference" etc. will be broadly defined to illuminate early psychoanalytic theory. A psychohistorical perspective on initial attempts to create a psychoanalytic pedagogy in Europe will be synthesized and current pre-school developmental programs in North America described, programs which draw from psychodynamic theory. The theories of Eric H. Erikson, Susan Isaacs, Bruno Bettelheim, E.C.M. Frijling-Schreuder and Margaret Ribble will be presented.In conclusion, some criticisms of the psychodynamic theories' impact on education will be aired.
Anatomical Response and Infection of Soybean during Latent and Pathogenic Infection by Type A and B of Phialophora gregata
Ann E. Impullitti, Dean K. Malvick
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0098311
Abstract: Growth and anatomical responses of plants during latent and pathogenic infection by fungal pathogens are not well understood. The interactions between soybean (Glycine max) and two types of the pathogen Phialophora gregata were investigated to determine how plants respond during latent and pathogenic infection. Stems of soybean cultivars with different or no genes for resistance to infection by P. gregata were inoculated with wildtype or GFP and RFP-labeled strains of types A or B of P. gregata. Plants were sectioned during latent and pathogenic infection, examined with transmitted light or fluorescent microscopy, and quantitative differences in vessels and qualitative differences in infection were assessed using captured images. During latent infection, the number of vessels was similar in resistant and susceptible plants infected with type A or B compared to the control, and fungal infection was rarely observed in vessels. During pathogenic infection, the resistant cultivars had 20 to 25% more vessels than the uninfected plants, and fungal hyphae were readily observed in the vessels. Furthermore, during the pathogenic phase in a resistant cultivar, P.gregata type A-GFP was limited to outside of the primary xylem, while P.gregata type B-RFP was observed in the primary xylem. The opposite occurred with the susceptible cultivar, where PgA-GFP was observed in the primary xylem and PgB-RFP was limited to the interfascicular region. In summary, soybean cultivars with resistance to BSR produced more vessels and can restrict or exclude P. gregata from the vascular system compared to susceptible cultivars. Structural resistance mechanisms potentially compensate for loss of vessel function and disrupted water movement.
A pilot study evaluating alternative approaches of academic detailing in rural family practice clinics
Hartung Daniel M,Hamer Ann,Middleton Luke,Haxby Dean
BMC Family Practice , 2012, DOI: 10.1186/1471-2296-13-129
Abstract: Background Academic detailing is an interactive, convenient, and user-friendly approach to delivering non-commercial education to healthcare clinicians. While evidence suggests academic detailing is associated with improvements in prescribing behavior, uncertainty exists about generalizability and scalability in diverse settings. Our study evaluates different models of delivering academic detailing in a rural family medicine setting. Methods We conducted a pilot project to assess the feasibility, effectiveness, and satisfaction with academic detailing delivered face-to-face as compared to a modified approach using distance-learning technology. The recipients were four family medicine clinics within the Oregon Rural Practice-based Research Network (ORPRN). Two clinics were allocated to receive face-to-face detailing and two received outreach through video conferencing or asynchronous web-based outreach. Surveys at midpoint and completion were used to assess effectiveness and satisfaction. Results Each clinic received four outreach visits over an eight month period. Topics included treatment-resistant depression, management of atypical antipsychotics, drugs for insomnia, and benzodiazepine tapering. Overall, 90% of participating clinicians were satisfied with the program. Respondents who received in person detailing reported a higher likelihood of changing their behavior compared to respondents in the distance detailing group for five of seven content areas. While 90%-100% of respondents indicated they would continue to participate if the program were continued, the likelihood of participation declined if only distance approaches were offered. Conclusions We found strong support and satisfaction for the program among participating clinicians. Participants favored in-person approaches to distance interactions. Future efforts will be directed at quantitative methods for evaluating the economic and clinical effectiveness of detailing in rural family practice settings.
Deliberation Scheduling for Time-Critical Sequential Decision Making
Thomas L. Dean,Leslie Pack Kaelbling,Jak Kirman,Ann Nicholson
Computer Science , 2013,
Abstract: We describe a method for time-critical decision making involving sequential tasks and stochastic processes. The method employs several iterative refinement routines for solving different aspects of the decision making problem. This paper concentrates on the meta-level control problem of deliberation scheduling, allocating computational resources to these routines. We provide different models corresponding to optimization problems that capture the different circumstances and computational strategies for decision making under time constraints. We consider precursor models in which all decision making is performed prior to execution and recurrent models in which decision making is performed in parallel with execution, accounting for the states observed during execution and anticipating future states. We describe algorithms for precursor and recurrent models and provide the results of our empirical investigations to date.
Goodman’s New Riddle of Induction  [PDF]
Dean Lubin
Open Journal of Philosophy (OJPP) , 2012, DOI: 10.4236/ojpp.2012.21009
Abstract: In this paper, I consider Goodman’s new riddle of induction and how we should best respond to it. Noticing that all the emeralds so far observed are green, we infer (project) that all emeralds are green. However, all emeralds so far observed are also grue, so we could also infer that they are grue. Only one of these inductive inferences or projections could, however, be valid. For the hypothesis that all emeralds are green predicts that the next observed emerald will be green; whereas the hypothesis that they are grue predicts that it will blue. Goodman’s new riddle is the problem of saying why the inductive inference involving “green” is the valid one. Goodman’s own solution appeals to the idea of entrenchment. His idea is that “green” is a more entrenched predicate than “grue” in the sense that it has figured many more times in our past projections than has “grue”. In his view, this explains why “green” is projectible (can be used in valid inductive inferences) whereas “grue” isn’t. I argue that this response doesn’t go far enough and that we additionally need an explanation of why “green” is more entrenched than “grue”—that we are otherwise left with the unsatisfactory view that its superior entrenchment is a mere linguistic accident. I try to supplement Goodman’s solution with an explanation of this kind. I argue that “grue” is not entrenched be- cause past successful inductions involving “green” show that past projections that could have been made using what I call “grue-like” predicates—predicates which are like “grue” except that the times featuring in their definitions are past—would have been unsuccessful.
Modeling Population Growth: Exponential and Hyperbolic Modeling  [PDF]
Dean Hathout
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.42045
Abstract:

A standard part of the calculus curriculum is learning exponential growth models. This paper, designed to serve as a teaching aid, extends the standard modeling by showing that simple exponential models, relying on two points to fit parameters do not do a good job in modeling population data of the distant past. Moreover, they provide a constant doubling time. Therefore, the student is introduced to hyperbolic modeling, and it is demonstrated that with only two population data points, an amazing amount of information can be obtained, such as reasonably accurate doubling times that are a function of t, as well as accurate estimates of such entertaining topics as the total number of people that have ever lived on earth.

Can a Timeless God Act in the World?  [PDF]
Dean Lubin
Open Journal of Philosophy (OJPP) , 2016, DOI: 10.4236/ojpp.2016.61003
Abstract: Can a timeless God act in the world? The purpose of this paper is to address this question by exploring the nature of timeless God’s omniscience. In the first part I argue—having explored what it means to say that God is timeless—that we should think of a timeless God’s omniscience factually rather than propositionally i.e. that a timeless God doesn’t know all propositions, but does know all facts. One consequence of this view is that though everything (what we call past, present and future) is equally present in the mind of a timeless God, being timeless he doesn’t know which events are past, which are present and which are future. For example, he doesn’t know that what is presently happening in the world is presently happening. The central issue I then consider in the second part is whether his knowledge could really be of the right kind for him to act in the temporal world. I argue that though God has knowledge of all the events in the temporal world and even knows (perhaps) their temporal orderings, he is unable to intervene because to do so he would need to have the knowledge he lacks; namely, he would need to know which events in the temporal world are past, which are present and which are future.
Sine-Generated Curves: Theoretical and Empirical Notes  [PDF]
Dean Hathout
Advances in Pure Mathematics (APM) , 2015, DOI: 10.4236/apm.2015.511063
Abstract: Sine-generated curves belong to a class of intrinsic functions which describe a curve by specifying its “direction angle”. The curve is determined by ω, the maximum angle which the curve makes with the horizontal, and the fact that the direction angle changes in a sinusoidal fashion along the path. Sine-generated curves are shown to be excellent approximations to the path of minimal average curvature, and expressions for radius of curvature and curve sinuosity are derived.
Parenteral Nutrition Additive Shortages: The Short-Term, Long-Term and Potential Epigenetic Implications in Premature and Hospitalized Infants
Corrine Hanson,Melissa Thoene,Julie Wagner,Dean Collier,Kassandra Lecci,Ann Anderson-Berry
Nutrients , 2012, DOI: 10.3390/nu4121977
Abstract: Nutrition support practitioners are currently dealing with shortages of parenteral nutrition micronutrients, including multivitamins (MVI), selenium and zinc. A recent survey from the American Society of Enteral and Parenteral Nutrition (ASPEN) indicates that this shortage is having a profound effect on clinical practice. A majority of respondents reported taking some aggressive measures to ration existing supplies. Most premature infants and many infants with congenital anomalies are dependent on parenteral nutrition for the first weeks of life to meet nutritional needs. Because of fragile health and poor reserves, they are uniquely susceptible to this problem. It should be understood that shortages and rationing have been associated with adverse outcomes, such as lactic acidosis and Wernicke encephalopathy from thiamine deficiency or pulmonary and skeletal development concerns related to inadequate stores of Vitamin A and D. In this review, we will discuss the current parenteral shortages and the possible impact on a population of very low birth weight infants. This review will also present a case study of a neonate who was impacted by these current shortages.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0080378
Abstract: Objectives To describe current use of electronic prescribing (EP) in English acute NHS hospital trusts, and the use of multiple EP systems within the same hospital. Design Descriptive cross-sectional postal survey. Setting Acute NHS hospital trusts in England. Participants The survey was sent to chief pharmacists in all acute English NHS hospital trusts in 2011. Where trusts comprised multiple hospitals, respondents were asked to complete the questionnaire for their main acute hospital. Main Outcome Measures Prevalence of EP use in acute NHS hospitals; number of different EP systems in each hospital; stages of the patient pathway in which EP used; extent of deployment across the hospital; comprehensiveness regarding the drugs prescribed; decision support functionalities used. Results We received responses from 101 trusts (61%). Seventy (69%) respondent hospitals had at least one form of EP in use. More than half (39;56%) of hospitals with EP had more than one system in use, representing 60 different systems. The most common were systems used only for discharge prescribing, used in 48 (48% of respondent hospitals). Specialist chemotherapy EP systems were second most common (34; 34%). Sixteen specialist inpatient systems were used across 15 hospitals, most commonly in adult critical care. Only 13 (13%) respondents used inpatient electronic prescribing across all adult medical and surgical wards. Overall, 24 (40%) systems were developed ‘in-house’. Decision support functionality varied widely. Conclusions It is UK government policy to encourage the adoption of EP in hospitals. Our work shows that EP is prevalent in English hospitals, although often in limited clinical areas and for limited types of prescribing. The diversity of systems in use, often within the same hospital, may create challenges for staff training and patient safety.
