Learning Pharmacology in Mexico: A Survey of the Use and Views of Pharmacology Textbooks by Undergraduate Medical Students  [PDF]
Rosa Ventura-Martinez, Rebeca Aguirre-Hernandez, Jacinto Santiago-Mejia, Claudia Gomez, Rodolfo Rodriguez
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.51009
Abstract:

Background: To date, little is known about the view of medical students towards pharmacology textbooks. This study aimed to investigate the preferences of second-year medical students towards pharmacology textbooks, and to identify the factors involved in book selection. Methods: Second-year medical students of the Medical School at the National University of Mexico (classes of 2010, 2011, and 2012) were asked to select their preferred textbook for studying pharmacology and preparing for exams from a list of nine textbooks. They also completed a 19-item questionnaire to identify and evaluate the reasons for their preferences. Results: A total of 1323 students completed the questionnaire, representing 45.59% of all medical students enrolled in 2010-2012. The two textbooks most preferred by students were Goodman & Gilman (25.3%) and Rodriguez et al. (27.3%); preferences for the other books were Harvey & Champe (13.9%), Rang et al. (13.5%), or Katzung et al. (12.3%), and others (7.6%). The usefulness and the adequacy of content were deemed equally important by students when choosing a textbook. Conclusions: Goodman & Gilman, a well-known pharmacology textbook, and Rodriguez et al., a small-volume textbook, were preferred by these second-year medical students; their choices were based on relevant pharmacological information and adequacy of content.

Quantum Associative Memory
Dan Ventura,Tony Martinez
Physics , 1998,
Abstract: This paper combines quantum computation with classical neural network theory to produce a quantum computational learning algorithm. Quantum computation uses microscopic quantum level effects to perform computational tasks and has produced results that in some cases are exponentially faster than their classical counterparts. The unique characteristics of quantum theory may also be used to create a quantum associative memory with a capacity exponential in the number of neurons. This paper combines two quantum computational algorithms to produce such a quantum associative memory. The result is an exponential increase in the capacity of the memory when compared to traditional associative memories such as the Hopfield network. The paper covers necessary high-level quantum mechanical and quantum computational ideas and introduces a quantum associative memory. Theoretical analysis proves the utility of the memory, and it is noted that a small version should be physically realizable in the near future.
Initializing the Amplitude Distribution of a Quantum State
Dan Ventura,Tony Martinez
Physics , 1998,
Abstract: To date, quantum computational algorithms have operated on a superposition of all basis states of a quantum system. Typically, this is because it is assumed that some function f is known and implementable as a unitary evolution. However, what if only some points of the function f are known? It then becomes important to be able to encode only the knowledge that we have about f. This paper presents an algorithm that requires a polynomial number of elementary operations for initializing a quantum system to represent only the m known points of a function f.
A Quantum Computational Learning Algorithm
Dan Ventura,Tony Martinez
Physics , 1998,
Abstract: An interesting classical result due to Jackson allows polynomial-time learning of the function class DNF using membership queries. Since in most practical learning situations access to a membership oracle is unrealistic, this paper explores the possibility that quantum computation might allow a learning algorithm for DNF that relies only on example queries. A natural extension of Fourier-based learning into the quantum domain is presented. The algorithm requires only an example oracle, and it runs in O(sqrt(2^n)) time, a result that appears to be classically impossible. The algorithm is unique among quantum algorithms in that it does not assume a priori knowledge of a function and does not operate on a superposition that includes all possible states.
Quantum Harmonic Sieve: Learning DNF with a Classical Example Oracle
Dan Ventura,Tony Martinez
Physics , 1998,
Abstract: This paper has been withdrawn by the authors due to a problem with *efficiently* predicting the large fourier coefficients. It is being reworked and will be resubmitted in the near future.

A rede e o conhecimento La Red y el Conocimiento
Placida Leopoldina Ventura Amorim da Costa Santos,Vinicio Carrilho Martinez
Informa??o & Informa??o , 2000, DOI: 10.5433/1981-8920.2000v5n2p
Abstract: No futuro, com a crescente virtualiza o (tecnologia substituindo o espa o público da prática política), é que se mostrará se a democracia foi posta em rede (pública) ou se apenas foi “tecnologizada”, tornando-se a imagem mais cara do conceito, ou seja, “publicidade”. A articula o da idéia de rede com a experiência das bibliotecas públicas seria uma possibilidade na realiza o da intera o social e na constru o da cidadania.
English Language Learner Boys and Girls Reading and Math Achievement as a Function of Early-Exit and Late-Exit Bilingual Programs: A Multiyear, Statewide Analysis
Rosa Maria Martinez,John R. Slate,Cynthia Martinez-Garcia
Education Research International , 2014, DOI: 10.1155/2014/508459
Abstract: We examined the reading and math performance of English Language Learner boys and girls in Grades 3, 4, 5, and 6 as a function of early-exit or late-exit transitional bilingual education program. Texas Assessment of Knowledge and Skills Reading and Mathematics scores of all English Language Learner boys and girls who were enrolled in either early-exit or late-exit bilingual education programs were analyzed for the 2008-2009, 2009-2010, and 2010-2011 school years. Results were not consistent across reading and math, across the 4 grade levels, and across the 3 school years. On the TAKS Reading test, 5 instances were present in which statistically significant differences were revealed for boys and 11 for girls. On the TAKS Mathematics test, 8 statistically significant results were revealed for boys and 6 for girls. These statistically significant differences were not consistently in favor of either the early-exit or the late-exit bilingual education programs. Moreover, the differences that were present reflected small to trivial effect sizes. As such, neither the early-exit nor the late-exit bilingual education program was demonstrated to be more effective than its counterpart. 1. Introduction Transitional bilingual education can be an early-exit or a late-exit bilingual program designed to help students acquire and improve English skills [1, 2] and to encourage a language shift for language minority students [3]. In the United States, the transitional bilingual education program is the instructional model most utilized in schools for English language development [2]. The transitional bilingual education instructional model provides students’ instruction in the first language in literacy and content areas and transition instruction to English [2]. In an early-exit bilingual program, students study subject matter in their primary language and English [4]. The primary purpose of the program is to facilitate the transition of English Language Learners to an English-only instructional classroom, while receiving academic subject instruction in the primary language to the extent necessary [1, 5]. In early-exit bilingual programs, students transition into English-only classroom within 2 to 3 years of achieving English language proficiency and all students are of the same linguistic background [2, 6]. Students in transitional bilingual programs learn to read in their home language and then in English [4]. The duration of the program and amount of native language instruction vary in each classroom, school, and district. Most campuses follow the 90/10 model, in

Under the Flag of Blue and White: Mary as an A-NationalSymbol in the Greek-Orthodox Community in Israel  [PDF]
Jonathan Ventura
Sociology Mind (SM) , 2011, DOI: 10.4236/sm.2011.14029
Abstract: Marian devotion and rituals have been the apex of Christian believers’ journey for centuries. In spite of its importance in many disciplines, Marian devotion and rituals in Israel have been neglected. In this article I will outline several social and religious aspects of Marian devotion in the Greek-Orthodox community in Israel. Using several case-studies of Marian devotion around the world I will address the question is Mary a national symbol in Israel? Since one of the most important Marian devotion sites is located in Israel and centered in Mary’s place of ascension in Gethsemane, addressing this site directly is crucial. I will express a new concept more fitting to the Israeli case—Mary as an a-national symbol. This research is based upon a combination of two main methodologies: participant observations and in-depth interviews with believers (local Greek and Palestinian residents as well as pilgrims) and clergymen. The research focuses on a procession taking place in the Old City of Jerusalem in the end of August, celebrating Mary’s legacy and resurrection.
