Forces Hampering Organizational Learning in a Military Organization: A Qualitative Case Study
No full textAbstract: A rigid, traditional, hierarchical organizational structure, typical of many military organizations is no longer seen as effective in terms of anticipating and responding to fast moving changes in the external environment in the modern era. Such structures leave decision-making and directives largely in the hands of a few individuals at the top of the organizational pyramid which is not conducive to the rapid and seamless implementation of policies and strategies in response to changing circumstances. Military organizations stand to benefit if they endorse some of the organizational learning approaches adopted by learning organizations which are better equipped to deal with change. This paper limits itself to looking at the various structural and behavioral characteristics identified in a particular military organization that are deemed to act as impediments to organizational learning and which stand in the way of its potential transition to a learning organization. An examination of these obstacles forms an important part of a wider qualitative, single-case, descriptive study which set out to determine how this particular military organization could turn itself into a learning organization. The study looked at various aspects of organizational learning within the case organization in order to determine the extent to which these corresponded to the way learning is promoted and managed within learning organizations and to identify a transformational pathway towards becoming a learning organization. Data was collected from a document review, observations blended with informal conversations and via in-depth interviews. The findings outlined in this paper highlight the ways in which the case organization was not functioning as a learning organization and identified the kind of transformational policies that need to be put in place.

Measurement of urinary kidney injury molecule-1 as a predictive biomarker of contrast-induced acute kidney injury
No full textObjective The aim of the present study is to evaluate the urinary KIM-1 level in the patients after 24 h angiography as a predictive biomarker of contrast-induced acute kidney injury.
Methods This study included 80 selective patients attending in the cardiology unit (48 males, 32 females). The study was conducted in the cardiac catheterization unit at Al- Hussein Medical City/ Kerbala. Clinical examination and laboratory investigations were made before and 24 h after angiography, these investigations include: serum creatinine, blood urea and estimated GFR. Urinary KIM-1 was measured before and after 24 h angiography.
Results There was no signifcant difference in urinary KIM-1 when compared between CIN and non CIN group P > 0.05. The level of urinary KIM-1 increased in the patients after 24 h of angiography when compared with baseline level of P < 0.001.
Conclusion Urinary KIM-1 was not useful for predicting or detecting CIN. But urinary KIM-1 level may be useful as a biomarker for tubular damage following intravascular administration of contrast media, 24 h
Eggshell membrane as a novel bio sorbent for remediation of boron from desalinated water
No full textThis study investigated the use of eggshell membrane (ESM) as a bio-sorbent and the effect of temperature, pH, and initial concentration on its efficiency. Furthermore, by altering the chemical composition, modified eggshell membrane (MESM) was prepared, and its efficiency was compared with the ESM. Results showed that the adsorption of boron preferred an acidic condition; pH 6 at 35 �C. In addition, the positive value of ?H� suggested that the reaction favored endothermic pathway, while the negative value for ?G� further suggested that the adsorption process was spontaneous. Furthermore, the ESM could adsorb 97% of boron, while MESM was able to adsorb 95%. From the Fourier transform infrared (FTIR), different functional groups were recorded on the surface of the ESM and MESM, and they played key role in the boron adsorption mechanisms. Linear Freundlich model was suggested to best describe the experimental data with 99.4% correlation coefficient. 2017 Elsevier LtdThe publication was made possible by UREP grant # [ 20-119-1-021 ] from Qatar National Research Fund (a member of Qatar foundation).

The history of Sumaniyyah (Buddhism) and its doctrine in the Arabic-Islamic discourse: an analysis
No full textThis paper reviews the history of Sumaniyyah doctrines in the Arabic-Islamic discourse. The author collates diverse materials on Sumaniyyah from various Arabic sources to analyze and characterize them. Beginning with the term's origin, Sumaniyyah's etymology, homonymy and historical background are explored to clarify similarities and differences between what was called Sumaniyyah and Buddhism. The methodology used is qualitative description and contents analysis with a focus on what early Muslim scholars wrote on Sumaniyyah until the 13th century of hijrah. The writers, highlight key doctrines including the transmigration of soul, idol worship, concepts of universe and creation, the belief in prophecy, the belief in the world's eternal nature, and limitations on certain types of knowledge
Silicate solubilizing bacteria as an option for concrete remediation.
No full textConcrete is one of the largest components in construction and development waste each year. According to the EPA (2020) concrete accounted for 67.5% of this total waste generation. Modern concrete can take up to 5 decades to decompose in a landfill. The ongoing pressure for sustainable and recyclable products has pushed for a solution that can quickly remediate this concrete waste. Modern concrete is a mixture of water, aggregate, and cement. Cement is the component in concrete that binds the rock or other aggregates together during the curing process. Portland cement, which is the binding component in this study, is composed of gypsum and calcium compounds including tricalcium trisilicate and tetracalcium aluminoferrite (Bye, 1999). Each component is found in varying ratios, but the highest percent compound is tricalcium silicate, which makes up 50% of the binding agent.
Bacteria have been identified that can solubilize silicate compounds. These silicate-solubilizing bacteria (SSB) amplify weathering for rocks in nature, and the free silicate is used as a nutrient for the plants. These bacteria have been used in agriculture as a way to supplement the nutrients to rice and wheat. Currently, SSB have been identified in the genera Bacillus, Burkholderia, Janthinobacterium, Aminobacter, and Pseudomonas (Raturi et al., 2021). These genera and other unidentified SSB could help with the issue of concrete waste as it contains high levels of silicates, and it could allow the concrete to replenish nutrients for plant growth in agricultural habitats.
The aim of this study is to identify silicate-solubilizing bacteria and determine the efficacy of the bacteria to break down the cement holding commercial concrete together. A secondary aim is to find an option that is cost effective and environmentally safe.
Using the differential medium by Bunt and Rovira I identified several bacteria from our standard lab culture collection that were capable of solubilizing silicate. The mechanism for silicate solubilization is thought to rely on acid production from the bacteria, so the identified bacteria were tested to determine the acid production in glucose-rich culture media. Serratia marcescens was selected as the best candidate from the results of this experiment. Due to the alkaline nature of concrete curing, the bacteria were then tested for survivability in media that contained concrete fragments and powdered concrete. This was completed with absorbance readings and plate counts sampled from the trial. Serratia marcescens was then added to containers with ~5-g fragments of concrete. A dry weight determination was taken before and after each trial as a measure of efficacy. The samples were incubated at room temperature (22–25ºC) and pH was monitored periodically for the two-week trial period. To ensure any change in weight was due to the bacteria and not the media, cell-free controls were run concurrently. The results showed a significantly greater change in weight in trials with bacteria. Based on these results I ran trials that contained bacterial supernatant as well as trials with commercially purchased acids to determine if the presence of the bacteria was necessary. The results showed that the supernatant had no significant change on the concrete. The pure acid had mixed results with acetic acid outperforming the bacterial trials and the others tested being ineffective. These results confirmed that the bacteria are capable of
degrading the concrete faster than in its natural state and gives support to the hypothesis that acid production is important to concrete remediation for SSB.Restricted until 06/2023. To request the author grant access, click on the PDF link to the left

The Impact of Irregular Status on Human Development Outcomes for Migrants
No full textThe purpose of this paper is to explore how irregular status impacts a range of human development outcomes for labour migrants. The analysis indicates that for poorer labour migrants, irregular (or undocumented) migration provides a positive, private return to income and livelihood improvements for themselves and their families as compared to 1) no movement at all, and at times, 2) regular (or documented) migration. However, irregular status is associated with a range of forms of disadvantage and vulnerabilities that often compromise migrants’ rights, entitlements and the rate of return they achieve from the migration process. Migrants are as rational as other members of the population and, being aware of these vulnerabilities, many still choose to migrate. The larger hypothesis of this paper is that, as long as poverty drives migration, legal status will not be a priority for migrants. Migrants will be willing to endure short to medium term hardship and the undermining of a range of capabilities and rights (such as education, social assets, rights and personal welfare) to provide economic safety nets for their families and future improvements to their (and their families) livelihoods and wellbeing. As long as migrants on average achieve a positive increase in income and assets through the migration experience (which they do) they will sacrifice a whole range of freedoms and rights. It is therefore imperative that policy makers make active steps to protect migrants with regard to basic human rights and facilitate positive outcomes from their migration experiences. In particular, we urge southern governments to advocate for all their migrants abroad, regardless of legal status. If southern country governments accept the mainstream opinion that migration is good for development, and furthermore recognise that a substantial number, if not the majority, of their migrants are irregular, and continue sending remittances and investment, then governments should seek to protect their citizens aboard, facilitate safe remittances, and begin to stand firm in the face of pressure to control national borders.Irregular status, migration, vulnerability, poverty, protection

Expression of the Frizzled Receptors and their Co-receptors in Calcified Human Aortic Valves
No full textThe cellular mechanisms that induce calcific aortic stenosis are yet to be unravelled. Wnt signaling is increasingly being considered as a major player in the disease process. However, the presence of Wnt Frizzled receptors (Fzd) and co-receptors LRP5 and 6 in normal and diseased human aortic valves remains to be elucidated. Immunohistochemistry and qPCR were used to determine Fzd receptor expression in normal and calcified human aortic valve tissue, as well as human aortic valve interstitial cells (HAVICs) isolated from calcified and normal human aortic valves. There was significantly higher mRNA expression of 4 out of the 10 Fzd receptors in calcified aortic valve tissues and 8 out of the 10 in HAVICs, and both LRP5/6 co-receptors in calcified aortic valves (PThe accepted manuscript in pdf format is listed with the files at the bottom of this page.
