Correlation Among Different Variables and Life Expectancy
June Liu
Undergraduate Journal of Mathematical Modeling : One + Two , 2011, DOI: 10.5038/2326-3652.3.2.2
Abstract: The purpose of this project is to show how heart rate, blood pressure, and weight of different species correlate with their life expectancy. We perform graphical analysis and compute Pearson's Product-Moment Correlation Coefficient to show that the heart rate has the highest degree of correlation with life expectancy.
The Models of Investing Schools  [PDF]
June Liu, Lei Chai, Zina Xu
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.46113
Abstract: In this paper, we build the Linear Programming (LP) model, factor analysis model and return on investment model to measure the investment amount and which year to invest of each selected schools. We firstly analyze the indicators from attached files, and select effective indexes to choose schools donated. Then we select 17 indexes out after preprocessing all the indices. Secondly, we extract 1064 schools by MATLAB which is the Potential Candidate Schools from the table of attached files; we extract 10 common factors of these schools by factor analysis. After calculation, we rank the universities and select the top 100. We calculate the Return on Investment (ROI) based on these 17 indexes. Thirdly, we figure out the investment amount by conducting LP model through MATLAB. According to the property of schools, we calculate the annual limit investment and the mount of investment of each school. Fourthly, we determine which year to invest by ROI model which is operated by LINGO. In order to achieve optimal investment strategy and not duplication of investment, for five years, starting July 2016, we assume that the time duration that the organization’s money should be provided is one year, and the school return to the Good grant Foundation only one year. Then we can get the investment amount per school, the return on that investment, and which years to invest. Fifthly, by changing parameter, the sensitivity analysis is conducted for our models. The result indicates that our models are feasible and robust. Finally, we evaluate our models, and point out the strengths and weakness. Through previous analysis, we can find that our models can be applied to many fields, which have a relatively high generalization.
Statistical Application in Economics  [PDF]
June Luo
Open Journal of Statistics (OJS) , 2012, DOI: 10.4236/ojs.2012.21013
Abstract: Statisticians have recently proposed some methods for ranking the gene variables with outlier expressions. The major attraction of these methods is their ability to select the variables which show systematic decrease or increase in only a subset of samples in the disease group. In order to fully account for the outliers, in this article, we truncate the expression values and propose an alternative method to rank the variables with systematic increase or decrease. The proposed statistic is very simple to implement. Simulations and real data study show that the proposed statistic has a more powerful ability to rank the variables than some methods in literature.
A sensitive and specific blocking ELISA for the detection of rabbit calicivirus RCV-A1 antibodies
Liu June,Kerr Peter J,Strive Tanja
Virology Journal , 2012, DOI: 10.1186/1743-422x-9-182
Abstract: Background Antibodies to non-pathogenic rabbit caliciviruses (RCVs) cross-react in serological tests for rabbit hemorrhagic disease virus (RHDV) and vice versa, making epidemiological studies very difficult where both viruses occur. It is important to understand the distribution and interaction of the two viruses because the highly pathogenic RHDV has been used as a biocontrol agent for wild rabbits in Australia and New Zealand for the past 17 years. The presence of the benign RCV Australia 1 (RCV-A1) is considered a key factor for the failure of RHDV mediated rabbit control in cooler, wetter areas of Australia. Results A highly sensitive and specific blocking ELISA was developed for the detection of RCV-A1 antibodies. When sera from rabbits with a known infection history for either RCV-A1 or RHDV were tested, this assay showed 100% sensitivity and no cross-reactivity with RHDV sera (100% specificity). Conclusions This new ELISA not only allows the detection of RCV-A1 at a population level, but also permits the serological status of individual rabbits to be determined more reliably than previously described methods. This robust and simple to perform assay is therefore the tool of choice for studying RCV-A1 epidemiology in Australian wild rabbit populations.
MAC Frame Resolution and PHY Protocol Type Detection of IEEE 802.11  [PDF]
Ling Li, Shi Peng, June Li, Kai Yuan, Zhihao Wang, Yinbin Liu, Ping Chen, Xianbing Wang
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2017, DOI: 10.4236/ijcns.2017.105B005
Frame resolution and physical layer (PHY) protocol type detection are the basis of research and development of intrusion prevention systems for IEEE 802.11 wireless network. Aiming at the problems which cannot be solved by the specifications export, this paper proposed a MAC frame analytical method and a PHY protocol type detection algorithm based on parsing the IEEE 802.11packets captured by the library Libpcap. The packet structure and the length of the frame preamble (18 or 26 bytes) are presented. Then the methods of transforming byte-order and resolving sub-fields are given. A detection algorithm of PHY protocol type is proposed based on the experiments and examples are given to verify these methods. This work can be a reference for the R & D related to link layer frame analysis.
The design, development and evaluation of a self-instructional module for nursing practice standards  [PDF]
June Anonson, Mary Ellen Walker
Open Journal of Nursing (OJN) , 2013, DOI: 10.4236/ojn.2013.38073

The purpose of this research was to improve nursing professionals’ understanding of the important link to safe, competent, and ethical practices that Nursing Practice Standards (NPS) serve. This research on NPS may improve the scope and comprehensiveness by which the Standards are integrated with clinical, educational, administrative, and research-based nursing practices. This research was unique in that it includes nurses in developing NPS. The method by which this study was done involved sixteen practicing nurses and seven instructional design experts from Alberta, Canada participating in designing, developing, and evaluating a NPS module. Nursing practice standards are a vital aspect of performing safe, efficient and effective patient care. The manner in which Nursing Standard Practices are presented and taught will directly influence a nurse’s ability to understand the value of NPS and successfully incorporate NPS into practice.

Analysis of CO2 Fluxes: Inclusion of Wall Conductance (Gw) on the Estimation of Rubisco Activity, Vcmax of Soybean Leaves
HAYATI Journal of Biosciences , 2011,
Abstract: In global change research, where modelling of CO2 fluxes from plants is an important component in determining vegetation capacity to protect the climate, mechanistic-based modelling is needed when projection of future CO2 absorption dynamics need to be estimated more accurately. Rubisco is the world’s most abundant protein in plants and has the job of uniquely preparing CO2 for chemical reduction. Rubisco activity in the leaf, described by Vcmax, can be estimated from gas exchange measurements of the initial slope of the response of CO2 assimilation rate, A, to intercellular [CO2]. This technique of estimation is favourable because it can avoid the uncertainties and difficulties when Vcmax is obtained directly by extraction and biochemical assay in artificial media. Rate of assimilation of soybean plants grown at different temperature (20/15, 25/20, and 32/27 oC day/night temperature) and [CO2] (350 and 700 mol mol-1), were measured using gas exchange. The effect of wall conductance (gw) on the parameterization of assimilations rate was observed. The temperature dependence of Vcmax depends strongly on wall conductance, where the shape of the curve would change significantly if finite wall conductance were included in the analysis. The implication is that it changes the values and interpretation of the temperature response of assimilation rate.
A Second Chance: The University of Cape Town's Diploma in Education
June Saldanha
Gateways : International Journal of Community Research & Engagement , 2009,
Abstract: This paper describes a curriculum that gives men and women from predominantly black working class communities a second chance to acquire a formal qualification at a higher education institution in South Africa. The curriculum provides the space for adult students to think critically about themselves and their practice and to develop a confident voice to express themselves. Through this process they develop both learner and educator identities and begin to see how the two intersect. The paper gives some of the historical background of the course, and shows how lecturers who have taught on the programme at different times have helped shape the curriculum. It goes on to discuss the changing nature of the student intake, the curriculum content and structure and ends with a discussion of the impact of the course, on students, staff and on the university as a whole. One very visible impact of the diploma is to be seen in the students who have gone on to acquire other postgraduate qualifications in adult education studies. On a university-wide level, through the involvement of adult education lecturers in other programmes and curricula, knowledge of and interest in adult learning is shared and encouraged.
Development to Unite Us: Autonomy and Multicultural Coexistence in Chiapas and Guatemala
June Nash
New Proposals : Journal of Marxism and Interdisciplinary Inquiry , 2008,
Abstract: Development was the buzz word in United States policy when I began my first field work as a student in Cantel, Guatemala, in 1953. The people of that much beleaguered country were still enjoying the “springtime of democracy” brought by the 1944 revolution that introduced land reform and education to the western highlands indigenous towns. I witnessed the U.S. instigated coup of 1954 that toppled the government of Arbenz and installed the puppet government of Colonel Castillo Armas. Thousands of union leaders and political activists were imprisoned or exiled, cattle owners released their herds into the lands taken over by peasants, a new order was installed in power claiming to bring prosperity and trade in the coming years. I went on to work in Chiapas in 1957 where the Mexican government was just beginning to introduce National Indigenist Institute programs for the integration of highland Mayas into the nation. These experiences shaped my understanding of what development from above meant in two countries that bridged the territory of the Mayan civilization. In this article I sum up the results of these two dominant patterns of development, one culminating in genocide and the other in ethnocide of the indigenous populations. The opening up of trade and enterprise with both countries has spawned new development programs such as the Plan Pueblo Panama embracing central American countries and southern Mexico in megaprojects to facilitate free trade agreements with the U.S. and Canada. These neoliberal policies aggravate the outpouring of resources that now include human labour power. I contrast this development with local initiatives now proposed by Mayas on both sides of the border.
The International Classification For Nursing Practice Project
Clark, June
Online Journal of Issues in Nursing , 1998,
Abstract: The rationale for standardised languages and classifications for nursing applies all over the world. Development in the USA was earlier than in other countries because of the imperatives of reimbursement systems, accreditation; and litigation. However, translation of languages developed in and for the USA may not be appropriate for other countries' practice; cultures, or health care systems. Many countries are already developing their own systems in their own languages, but others have no system. The International Council of Nurses' project to develop an International Classification for Nursing Practice will provide a unifying framework for existing systems and a system which can be used in countries which have none. Only when we have such a tool will we be able to describe and compare nursing practice across nations, and test the commonalties and differences of its concepts, values and practices.
