    Managing action research: the PEArL framework

    The difficulty of managing and validating Action Research field studies has been widely discussed. Several different approaches to Action Research have emerged, and one of the most widely used models is Checklandā€™s FMA model, where a framework is provided to facilitate interested individuals in ā€˜recoveringā€™ the route of the inquiry. In this paper, I argue that the FMA model is a valuable tool for planning the application of theoretical ideas in a practical situation, but that, as a guide to Action Research, it still fails to provide a sense of the manner in which an inquiry is undertaken. The PEArL mnemonic has been previously offered as a guide to facilitate researchers, participants, and those interested in gaining an appreciation of the manner in which an inquiry is conducted. In this paper, it is argued that applying the PEArL elements does not provide insight into the dynamic nature of collaborative inquiry. In order to gain a sense of the manner in which an inquiry was undertaken it is necessary to apply the PEArL mnemonic alongside a framework that facilitates the flow of the action research cycle. To illustrate the framework, an Action Research field study is described that was undertaken with residents and key workers in a shelter for the homeless, where the aim was to create a shared understanding of complex needs and support requirements

    Trafficking defects and loss of ligand binding are the underlying causes of all reported DDR2 missense mutations found in SMED-SL patients

    Spondylo-meta-epiphyseal dysplasia (SMED) with short limbs and abnormal calcifications (SMED-SL) is a rare, autosomal recessive human growth disorder, characterized by disproportionate short stature, short limbs, short broad fingers, abnormal metaphyses and epiphyses, platyspondyly and premature calcifications. Recently, three missense mutations and one splice-site mutation in the DDR2 gene were identified as causative genetic defects for SMED-SL, but the underlying cellular and biochemical mechanisms were not explored. Here we report a novel DDR2 missense mutation, c.337G>A (p.E113K), that causes SMED-SL in two siblings in the United Arab Emirates. Another DDR2 missense mutation, c.2254C>T (p.R752C), matching one of the previously reported SMED-SL mutations, was found in a second affected family. DDR2 is a plasma membrane receptor tyrosine kinase that functions as a collagen receptor. We expressed DDR2 constructs with the identified point mutations in human cell lines and evaluated their localization and functional properties. We found that all SMED-SL missense mutants were defective in collagen-induced receptor activation and that the three previously reported mutants (p.T713I, p.I726R and p.R752C) were retained in the endoplasmic reticulum. The novel mutant (p.E113K), in contrast, trafficked normally, like wild-type DDR2, but failed to bind collagen. This finding is in agreement with our recent structural data identifying Glu113 as an important amino acid in the DDR2 ligand-binding site. Our data thus demonstrate that SMED-SL can result from at least two different loss-of-function mechanisms: namely defects in DDR2 targeting to the plasma membrane or the loss of its ligand-binding activity

    Extrovert Followership and its Impact on Agreeable Leadership

    This study recons the need for research on effective role of followership in mentoring a leader to set pattern or direction for leader. A reinvented concept of leader being a team man needs active participation from followers in changing business dynamics. The sample consisting of middle level management having leader (heads/ supervisors from education sector) above it has been taken and results are achieved using inferential statistics, so to verify the need of followers for result oriented leadership. The results depict that certain personality traits backed by ā€œBig Five Modelā€ are found to be important for followers to have an impact on leaderā€™s decision making. As this study analyses the mutual characteristic of leader follower relation statistically while putting follower on the fore front, the originality of study is ensured. As for limitation, this study may show different results as per variant geographical and economical regions in which followersā€™ expectations may vary accordingly

    Genetic Inactivation of Trpml3 Does Not Lead to Hearing and Vestibular Impairment in Mice

    TRPML3, a member of the transient receptor potential (TRP) family, is an inwardly rectifying, non-selective Ca2+-permeable cation channel that is regulated by extracytosolic Na+ and H+ and can be activated by a variety of small molecules. The severe auditory and vestibular phenotype of the TRPML3(A419P) varitint-waddler mutation made this protein particularly interesting for inner ear biology. To elucidate the physiological role of murine TRPML3, we conditionally inactivated Trpml3 in mice. Surprisingly, lack of functional TRPML3 did not lead to circling behavior, balance impairment or hearing loss

    A comparative clinical study of Shatavari Ghrita aschyotana and Carboxy methyl cellulose 0.5% eye drop in the management of dry eyes with special reference to smartphone users

    Advanced technologies like computers, Internet surfing, Smartphone use, T.V., use of Air conditioners, more polluted dusty hot environment etc. has completely changed the World. Due to this long-term exposure to visual display terminal a new group of eye and vision problems has emerged with dry eyes. Dry Eye disease is an inflammation of cornea and conjunctiva due to inadequate secretion of tears. No specific remedial measures have been mentioned for Dry Eye Disease in modern medicine. Considering all the lacunas of established treatment and increased prevalence rate of disease due to changing lifestyle it is necessary to look for alternative therapy which is safe, cheap, easily available, and more effective. Aim: To evaluate and compare the effect of Shatavari Ghrita Aschyotana and Carboxymethylcellulose 0.5%eye drop in patients suffering fromĀ Ā  Shushkakshipaka (Dry eye syndrome). Material and methods: A total 70 patients of the age group 20-30 years presenting with signs and symptoms of Shushkakshipaka w.s.r. to dry eye disease were selected randomly from OPD of the department of Shalakyatantra. The 35 patients of trial group were treated with Shatavari Ghrita Aschyotana and 35 patients of control group were subjected to Carboxymethylcellulose 0.5% eye drop. Results: Shatavari Ghrita Aschyotana is more effective as compared to Carboxymethylcellulose 0.5% eye drop.
