On Being a Juror: A Phenomenological Self-Study
LD Fortune
Indo-Pacific Journal of Phenomenology , 2009,
Abstract: Phenomenological inquiry offers a vehicle for transcending conventional disciplinary boundaries and investigative settings. Van Manen's protocol writing offers a hermeneutic tool for human scientific phenomenological research that is ideal for the empirical realm of everyday lived experience. Underlying this approach is the tenet that interpretative phenomenological research and theorizing cannot be separated from the textual practice of writing. The entirety of this paper is a protocol, in the form of a phenomenological self-study. It describes one experience in an unfamiliar environment as a criminal trial juror. It represents data capture that can stand alone for purposes of independent interpretation. Since qualitative research in the venue described is limited by protective judicial restrictions, this phenomenological protocol captures unique data in an otherwise inaccessible setting. It suggests that protocol writing offers potential as a research tool in a myriad situations where conventional data collection techniques are impractical or unavailable.

Practice, Behavior, Knowledge and Awareness of Food Safety among Secondary & Tertiary Level Students in Trinidad, West Indies  [PDF]
Susan Turnbull-Fortune, Neela Badrie
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.515160
Abstract:

The aim of this study was to assess the level of food safety practice, knowledge, behavior and awareness among n = 205 Trinidadian students (mean age 18±) enrolled within the education system in the Republic of Trinidad and Tobago, West Indies and to explore the association between these variables and the demographic and educational characteristics. To address these concerns, participants enrolled within the secondary (high school) and tertiary (university) institutions in Trinidad were questioned (16 questions) on food buying habits, preparation, attitudes, behaviors, knowledge and awareness. The data were analyzed using SPSS for descriptive, frequency distribution and percentages. Pearson chi square tested the association between food safety behaviors and awareness in relation to gender, age and educational level. Findings indicated that 76%of the students “always” washed their hands after touching raw chicken/meats and fish, while 50% utilized separate cutting boards/knives for raw chicken/meat and fish. Many students (68%) believed that it was “very safe” to only rinse cutting boards used for raw chicken/meat and fish. Others (10%) believed it was “very safe” to defrost foods outside the refrigerator, and 25% reported that it was “safe” to leave hot foods at room temperature for more than four hours. The level of food safety practice and behavior was higher (p < 0.05) among the female students at the secondary school level than those at the tertiary level. There was no difference in the median (20/45) and mode (25/45) scores for food safety behavior between the two educational groups but the difference (p < 0.01) was significant for awareness. Food safety practice, behavior and awareness skills of males at the secondary level were significantly lower (p < 0.01) than the females. These results strengthen the need for continuous educational programs to improve food safety awareness skills of Trinidadian students.

Why Production Function Analysis is Irrelevant in Policy Deliberations Concerning Educational Funding Equity
Jim C. Fortune
Education Policy Analysis Archives , 1993,
Abstract: Hanushek and Walberg use production function methodology to contend that there is no relationship between school expenditures and student achievement. Production function methodology uses correlational methods to demonstrate relationships between input and output in an economic system. These correlational methods may serve to hide rather than reveal these relationships. In this paper threats to the validity of these correlational methods for analysis of expenditure-achievement data are discussed and an alternative method of investigation is proposed. The proposed method is illustrated using data from two states (Ohio and Missouri). The method demonstrates relationships between expenditures and achievement that were overlooked by the production function method.
The Universal Connection and Metrics on Moduli Spaces

Physics , 2003, DOI: 10.1007/s00220-004-1191-7
Abstract: We introduce a class of metrics on gauge theoretic moduli spaces. These metrics are made out of the universal matrix that appears in the universal connection construction of M. S. Narasimhan and S. Ramanan. As an example we construct metrics on the c_{2}=1 SU(2) moduli space of instantons on R^4 for various universal matrices.
Situs invertus totalis in a child with chronic sinusitis  [PDF]
Chinawa Josephat Maduabuchi, Ujunwa Fortune Amuche, Eze Chukwubuike Uzodinma
Open Journal of Pediatrics (OJPed) , 2013, DOI: 10.4236/ojped.2013.33041
Abstract:

Background: Total situs inversus, (also called situs transversus or oppositus) known as mirror image dextrocardia, is characterized by a heart on the right side of the midline while the liver is on the left side. Situs Inversus Totalis (SIT) is a congenital anomaly characterized by complete transposition of abdominal and thoracic organs. Patients with this anomaly usually lead a normal life. We report a fourteen-year old Nigerian who was found to have dextrocardia with situs inversus totalis while presenting for treatment for a different problem. Conclusion: Situs inversus totalis is a rare finding. This report underscores the need for routine screening of children so that such congenital anomalies can be identified and complications that follow it averted timely.


Multicriteria Assessment of Various Onsite Wastewater Treatment Options for Nigeria  [PDF]
Chidozie Charles Nnaji, Chinedu Ekechukwu, Fortune Onyia, Christopher Afangideh
Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.52017
Abstract:

Eight onsite wastewater treatment systems (OWTS) were evaluated for suitability of application in Nigeria for efficient treatment and disposal of domestic wastewater, using analytic network process (ANP). Ten location related risks were used as criteria in the decision making process. Expert views were used to obtain pairwise comparison matrices of the OWTSs with respect to the criteria. Saaty’s Super Decision Software was used to complete the ranking process. The order of ranking obtained was as follows: septic tank with absorption field (0.1502) > septic tank with soakaway (0.142) > composting toilet (0.128) > septic tank with sand filter (0.125) > septic tank with constructed wetland (0.12) > septic tank with holding tank (0.12) > septic tank with mound system (0.118) > septic tank with recirculating sand filter (0.096). However, when the costs and life spans of these systems were incorporated into the ranks, and considering other factors, the septic tank with absorption field stood out as the best option. A simple sensitivity analysis shows that depth to water table, proximity to drinking water, susceptibility to flooding and proximity to large roots have the highest influence on the ranks of OWTSs.

The Neuronal Transition Probability (NTP) Model for the Dynamic Progression of Non-REM Sleep EEG: The Role of the Suprachiasmatic Nucleus
Helli Merica, Ronald D. Fortune
PLOS ONE , 2011, DOI: 10.1371/journal.pone.0023593
Abstract: Little attention has gone into linking to its neuronal substrates the dynamic structure of non-rapid-eye-movement (NREM) sleep, defined as the pattern of time-course power in all frequency bands across an entire episode. Using the spectral power time-courses in the sleep electroencephalogram (EEG), we showed in the typical first episode, several moves towards-and-away from deep sleep, each having an identical pattern linking the major frequency bands beta, sigma and delta. The neuronal transition probability model (NTP) – in fitting the data well – successfully explained the pattern as resulting from stochastic transitions of the firing-rates of the thalamically-projecting brainstem-activating neurons, alternating between two steady dynamic-states (towards-and-away from deep sleep) each initiated by a so-far unidentified flip-flop. The aims here are to identify this flip-flop and to demonstrate that the model fits well all NREM episodes, not just the first. Using published data on suprachiasmatic nucleus (SCN) activity we show that the SCN has the information required to provide a threshold-triggered flip-flop for timing the towards-and-away alternations, information provided by sleep-relevant feedback to the SCN. NTP then determines the pattern of spectral power within each dynamic-state. NTP was fitted to individual NREM episodes 1–4, using data from 30 healthy subjects aged 20–30 years, and the quality of fit for each NREM measured. We show that the model fits well all NREM episodes and the best-fit probability-set is found to be effectively the same in fitting all subject data. The significant model-data agreement, the constant probability parameter and the proposed role of the SCN add considerable strength to the model. With it we link for the first time findings at cellular level and detailed time-course data at EEG level, to give a coherent picture of NREM dynamics over the entire night and over hierarchic brain levels all the way from the SCN to the EEG.

Abstract: CO2 capturing, transport and sequestration by pressurized water dissolution and reacting by natural alkali lime and magnesia in coal fly ash or other sources become an industrial advantageous sequestration option resulting in green waste solutions or solid fines. Mg and Ca containing minerals are reacting with CO2 to form carbonates. Various types of fly ash materials may react with CO2 to form carbonate regarding ash composition and reaction parameters. Mineral sequestration of CO2 will also allow using the products in cement industry or as cement material in constructions with low cost. This paper discussed progress on coal mining filling by carbonation method using coal fly ash of Soma, Yatagan, Afsin Elbistan Power Stations. Other filler materials containing coal mine waste shale, fly ashes and foam concrete, and additives were searched for pretreatment methods to enhance cement reactivity; and in analyzing the structural changes to identify reaction paths and potential barriers.
