A Higher Education Leadership Distance Ph.D. Program: An Assessment Using Blocher’s Ecological Learning Theory  [PDF]
Linda Kuk, James H. Banning
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.59082
Abstract:

This study utilized a case study approach to discuss the issues of distance education in the delivery of doctoral education. The case study provided abroad background to the issues of distance education graduate programs and an assessment of the case. Blocher’s (1974) Ecological Learning Theory is applied to the case to provide for analytical generalization. The results support the need for distance delivery of academic programs to consider both the content and the program’s delivery structure as important components in realizing student success.

Creative Expression: Effectiveness of a Weekly Craft Group with Women Who Have Experienced Trauma  [PDF]
Linda Garner
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.52011
Abstract: Creativity interventions have been shown to positively influence psychological and emotional health indicators. Nurses can play an important role in the development and implementation of interventions designed to counter the longer-term emotional and psychological consequences of trauma. The purpose of this study was to explore how participation in a nurse-facilitated weekly craft group may influence anxiety, depression, self-esteem, and self-confidence among women who have emotional and physical experienced trauma. A pre/post visual analog scale was used during a 7-week intervention to measure changes in anxiety, depression, stress, self-esteem and self-confidence among a convenience sample of adult female trauma survivors (n = 33). A paired sample t test was used to evaluate the intervention with significance set at p = 0.05. Participant observation and field notes were used for qualitative data generation. Significant reductions were noted in anxiety, depression, and stress along with significant increases in self-esteem and self-confidence. Cohen’s d statistic indicated a large effect size for anxiety (0.72) and stress (0.69). Moderate effect size was determined for self-confidence (0.36), depression (0.41), and self-esteem (0.52). Emergent qualitative themes included: creative expression improved confidence to sooth the self, safe spaces fostered creativity, a sense of accomplishment was stimulated through creative activities, and creative expression groups provided opportunities for positive affirmation. Offered as a complementary intervention, nurse-facilitated creative expression groups can support continued healing long after traditional support services have been exhausted. It is important for nurses to pursue a greater understanding of the art of nursing and the important contribution of creativity when used as a nursing intervention with trauma survivors.
Residual Effects from Occupational Mercury Exposure Include a Proposed Mercury Tremor Biomarker or “Fingerprint”  [PDF]
Linda Jones
Journal of Environmental Protection (JEP) , 2017, DOI: 10.4236/jep.2017.810068
Abstract: The study investigated residual effects of high levels of occupational mercury exposure, 30 years after a cohort of women worked in public service dentistry. They had all used copper amalgam in a pellet form that required heating and handling, and silver amalgam before the encapsulated form was available. Mercury handling practices changed in the mid-1970 when the workforce was urine tested and mercury poisoning became apparent. The aim was to compare control group and exposed group scores on tasks from a neurobehavioural test battery; plus survey results from a composite health, work history and environmental influences survey. The findings showed that the exposed and control groups were equivalent not only on those variables that one would want to be matched (age, alcohol consumption), but also on many of the cognitive and psychomotor test scores. The present paper focuses on psychomotor skill and tremor patterns. Tremor patterns were seen as generating new evidence of long term effects of the historic mercury insult. Data also suggest that there may be a distinctive mercury “fingerprint”, in samples of sinusoidal waveforms that may have potential as a non-invasive sub-clinical biomarker for adverse effects of mercury exposure, in screening or workplace monitoring.

BMC Public Health , 2011, DOI: 10.1186/1471-2458-11-302
Abstract: An analysis based on 6,421 Canadian women, who had a live birth between 2005 and 2006 and were part of the Maternity Experience Survey (MES), was performed. PPDS was measured based on the Edinburgh Postnatal Depression Scale. Various factors that assessed socio-economic status, demographic factors, and maternal characteristics were considered for the multinomial regression model.The national prevalence of minor/major and major PPDS was found to be 8.46% and 8.69% respectively. A mother's stress level during pregnancy, the availability of support after pregnancy, and a prior diagnosis of depression were the characteristics that had the strongest significant association with the development of PPDS.A significant number of Canadian women experience symptoms of postpartum depression. Findings from this study may be useful to increase both the attainment of treatment and the rate at which it can be obtained among new mothers. Interventions should target those with the greatest risk of experiencing PPDS, specifically immigrant and adolescent mothers.Postpartum depression (PPD) refers to a non-psychotic depressive episode that begins in or extends into the postpartum period [1,2]. PPD can evolve from a preexisting case of the baby blues, or can become apparent after the first weeks of giving birth and can last as long as 14 months [1,3-5]. Symptoms include anxiety, guilt, negative maternal attitudes, and poor parenting self-efficacy [3,6,7]. A multitude of treatment options for PPD exist, including interpersonal therapy and the most common treatment, pharmaceutical intervention [1,8].Mothers who suffer from PPD endure significant consequences, especially with their ability to cope with life events, including parenting tasks [9]. PPD elicits negative clinical implications for maternal-infant attachment; there is a withdrawn and disengaged behaviour in the mother and/or intrusive and hostile mother-infant communication [10-13]. Research has shown that experiencing symptoms o
Stool sample storage conditions for the preservation of Giardia intestinalis DNA

Memórias do Instituto Oswaldo Cruz , 2012, DOI: 10.1590/S0074-02762012000800001
Abstract: stool is chemically complex and the extraction of dna from stool samples is extremely difficult. haemoglobin breakdown products, such as bilirubin, bile acids and mineral ions, that are present in the stool samples, can inhibit dna amplification and cause molecular assays to produce false-negative results. therefore, stool storage conditions are highly important for the diagnosis of intestinal parasites and other microorganisms through molecular approaches. in the current study, stool samples that were positive for giardia intestinalis were collected from five different patients. each sample was stored using one out of six different storage conditions [room temperature (rt), +4oc, -20oc, 70% alcohol, 10% formaldehyde or 2.5% potassium dichromate] for dna extraction procedures at one, two, three and four weeks. a modified qiaamp stool mini kit procedure was used to isolate the dna from stored samples. after dna isolation, polymerase chain reaction (pcr) amplification was performed using primers that target the β-giardin gene. a g. intestinalis-specific 384 bp band was obtained from all of the cyst-containing stool samples that were stored at rt, +4oc and -20oc and in 70% alcohol and 2.5% potassium dichromate; however, this band was not produced by samples that had been stored in 10% formaldehyde. moreover, for the stool samples containing trophozoites, the same g. intestinalis-specific band was only obtained from the samples that were stored in 2.5% potassium dichromate for up to one month. as a result, it appears evident that the most suitable storage condition for stool samples to permit the isolation of g. intestinalis dna is in 2.5% potassium dichromate; under these conditions, stool samples may be stored for one month.
Weighted gradient domain image processing problems and their iterative solutions
Jung Gap Kuk and Nam Ik Cho
EURASIP Journal on Image and Video Processing , 2013, DOI: 10.1186/1687-5281-2013-7
Abstract: This article explores an energy function and its minimization for the weighted gradient domain image processing, where variable weights are applied to the data term of conventional function for attaining better results in some applications. To be specific, larger weights are given to the regions where original pixel values need to be kept unchanged, like strong edge regions in the case of image sharpening application or high contrast regions when fusing multi-exposure images. In the literatures, it is shown that the solution to a constant weight problem can be efficiently obtained in the frequency domain without iterations, whereas the function with the varying weights can be minimized by solving a large sparse linear equation or by iterative methods such as conjugate gradient or preconditioned conjugate gradient (PCG) methods. In addition to introducing weighted gradient domain image processing problems, we also proposed a new approach to finding an efficient preconditioning matrix for this problem, which greatly reduces the condition number of the system matrix and thus reduces the number of iterations for the PCG process to reach the solution. We show that the system matrix for the constant weight problem is an appropriate preconditioner, in the sense that a sub-problem in the PCG is efficiently solved by the FFT and also it ensures the convergent splitting of the system matrix. For the simulation and experiments on some applications, it is shown that the proposed method requires less iteration, memory, and CPU time.
THE STRUCTURAL FABRIC AND SEISMOTECTONIC ACTIVITY OF NORTHERN VELEBIT: SOME NEW OBSERVATIONS
Eduard Prelogovi?,Vlado Kuk,Renato Buljan
Rudarsko-Geolo?ko-Naftni Zbornik , 1998,
Abstract: A permanent seismotectonic activity is present in the region of northern Velebit. Through history a number of earthquakes magnitudes of VIII° and IX° MCS are reported. In this century the most powerful earthquake of a magnitude of 5.8 occurred in 1916. The key tectonic movements that cause these earthquakes are dislocations of the Adriatic platform towards the north and the resistance of the Dinarides towards these movements. The tectonic dynamics of a structural arrangement depend on the relationship between stress and the deformation of structural units. According to the tectonic measurements performed on outcrops of major faults the following orientation of stress was obtained: from 20/25° to 200/205° in the northern Velebit region and 340 to 160° in the hinterland. Within the structural arrangement compression of space occurs which is well pronounced in the Novi Vinodolski area. Possible deformation of structures is manifested spatial diagonal reverse displacements accompanied by rotation of the structure. In the Velebit hinterland right horizontal tectonic transport was determined. In the zone of the transcurrent faull uta Lokva-Oto ac-Buni the spatial opening leads to the formation of pull-apart structures. Seismotectonically active zones occur in the contact region between the Adriatic platform and the Dinaridcs. Spatially its position is inclined and bent.

Saddlepoint methods for conditional expectations with applications to risk management
Sojung Kim,Kyoung-kuk Kim
Statistics , 2015,
Abstract: The paper derives saddlepoint expansions for conditional expectations in the form of $\mathsf{E}[\overline{X} | \overline{\mathbf Y} = {\mathbf a}]$ and $\mathsf{E}[\overline{X} | \overline{\mathbf Y} \geq {\mathbf a}]$ for the sample mean of a continuous random vector $(X, {\mathbf Y}^\top)$ whose joint moment generating function is available. Theses conditional expectations frequently appear in various applications, particularly in quantitative finance and risk management. Using the newly developed saddlepoint expansions, we propose fast and accurate methods to compute the sensitivities of risk measures such as value-at-risk and conditional value-at-risk, and the sensitivities of financial options with respect to a market parameter. Numerical studies are provided for the accuracy verification of the new approximations.
