Influence of squeeze-film damping on the dynamic behavior of a curved micro-beam
Authors: Ouakad Hassen M , Al-Qahtani Hussain M , Hawwa Muhammad A
Published: June 2016

A fixed–fixed curved micro-beam resonator under the influence of harmonic electrostatic field is considered. Due to the presence of incompressible fluid between the micro-beams and the electrode, a squeeze-film damping affects the dynamic behavior of the resonator. The combined effect of curved geometry and fluid squeeze-film damping is investigated for micro-beams with concave and convex geometries. A reduced-order model is obtained through the application of Galerkin discretization on a coupled fluid–structure system composed of the nonlinear Euler–Bernoulli beam equation and Burgdorfer’s model for the neighboring fluid. The dynamic behavior is assessed by investigating the influence of squeeze-film damping on the linear and nonlinear frequency response and the maximum resonant deflection of curved up and curved down micro-beams.

Published: June 2016

Background

Alternative medicine is noted for its clinical effect and minimal invasiveness in the treatment of neuropathic pain. Go-sha-jinki-Gan, a traditional Japanese herbal medicine, has been used for meralgia and numbness in elderly patients. However, the exact mechanism of GJG is unclear. This study aimed to investigate the molecular mechanism of the analgesic effect of GJG in a chronic constriction injury model.

Results

GJG significantly reduced allodynia and hyperalgesia from the early phase (von Frey test, p < 0.0001; cold-plate test, p < 0.0001; hot-plate test p = 0.011; two-way repeated measures ANOVA). Immunohistochemistry and Western blot analysis revealed that GJG decreased the expression of Iba1 and tumor necrosis factor-α in the spinal cord. Double staining immunohistochemistry showed that most of the tumor necrosis factor-α was co-expressed in Iba1-positive cells at day 3 post-operation. GJG decreased the phosphorylation of p38 in the ipsilateral dorsal horn. Moreover, intrathecal injection of tumor necrosis factor-α opposed the anti-allodynic effect of GJG in the cold-plate test.

Conclusions

Our data suggest that GJG ameliorates allodynia in chronic constriction injury model mice via suppression of tumor necrosis factor-α expression derived from activated microglia. GJG is a promising drug for the treatment of neuropathic pain induced by neuro-inflammation.
Family presence during resuscitation: Validation of the risk–benefit and self-confidence scales for student nurses
Authors: Bray Isabelle , Kenny Gerard , Pontin David , Williams Rachel , Albarran John
Published: June 2016

Background. There is increasing debate about the advantages and disadvantages of family-witnessed resuscitation. Research about the views of healthcare providers depends upon reliable tools to measure their perceptions. Two tools have been developed for use with nurses (26-item cost-benefit tool, 17-item self-confidence tool). Objectives. Firstly, to validate these tools for use with student nurses in the UK. Secondly, to report on the perceived risks and benefits reported by student nurses, and their self-confidence in dealing with this situation. Methods. A sample of 79 student nurses were invited to complete the tools. Item-total correlations and Cronbach’s α were used to determine internal consistency. Factor analysis was computed to assess construct validity. The correlation between the two scales was explored. Results. 69 students completed a questionnaire. Very few had experience of family-witnessed resuscitation. Mean total scores were 3.16 (standard deviation 0.37; range 2.04–4.12) on the risk-benefit scale and 3.14 (standard deviation 0.66; range 1.94–4.82) on the self-confidence scale. Four of the original items were removed from the risk-benefit scale (Cronbach's α 0.86; 95% confidence interval ≥0.82). None were removed from the self-confidence scale (Cronbach's α 0.93; 95% confidence interval ≥0.91). There was a significant correlation between the two scales ( r = 0.37, p = 0.002). Conclusions. There is growing evidence that these tools are valid and reliable for measuring student nurses’ perceptions about family-witnessed resuscitation.
Impact case studies submitted to REF 2014: The hidden impact of nursing research
Authors: Kelly Daniel , Kent Bridie , McMahon Ann , Taylor Julie , Traynor Michael
Published: June 2016

The UK’s Research Excellence Framework (REF) 2014 rated the research from 154 universities, and the impact of research was evaluated in 6975 impact case studies. Nursing was returned within unit of assessment (UoA) 3, which also included Dentistry, Pharmacy and Allied Health Professions, although nursing research was also submitted within other UoAs. The study aim was to collate and categorise available REF impact case studies involving nursing researchers or on topics of relevance to nursing. Using nurs* as a search term, 469 case study entries were retrieved from the REF database and placed into three categories determined by the level of involvement of nurses. Some 80 impact case studies were submitted by nurses across 11 units of assessment, the majority being in UoA 3 ( n = 55). A further 50 revealed some relevant impact, although nurses did not have an obvious research role. A total of 248 case studies described actual or potential impact on health or social care but were not associated specifically with nursing. Nursing research has demonstrable impact; however, there is a significant body of research with relevance for nursing that has not been associated with the profession in the REF. More attention should be paid to the ‘hidden impact’ of nursing research to ensure the full impact of nursing is recognised.
Non-normality and nonlinearity in thermoacoustic instabilities
Authors: Sujith RI , Juniper MP , Schmid PJ
Published: June 2016

Analysis of thermoacoustic instabilities were dominated by modal (eigenvalue) analysis for many decades. Recent progress in nonmodal stability analysis allows us to study the problem from a different perspective, by quantitatively describing the short-term behavior of disturbances. The short-term evolution has a bearing on subcritical transition to instability, known popularly as triggering instability in thermoacoustic parlance. We provide a review of the recent developments in the context of triggering instability. A tutorial for nonmodal stability analysis is provided. The applicability of the tools from nonmodal stability analysis are demonstrated with the help of a simple model of a Rjike tube. The article closes with a brief description of how to characterize bifurcations in thermoacoustic systems.
Reducing cranial computed tomography effective radiation dose by 30% using adaptive iterative dose reduction
Authors: Yu Wai-Yung , Ho Thye Sin , Ko Henry , Chan Wai-Yee , Ong Serene , Hui Francis Kim Hoong
Published: June 2016

Introduction:

The use of computed tomography (CT) imaging as a diagnostic modality is increasing rapidly and CT is the dominant contributor to diagnostic medical radiation exposure. The aim of this project was to reduce the effective radiation dose to patients undergoing cranial CT examination, while maintaining diagnostic image quality.

Methods:

Data from a total of 1003, 132 and 27 patients were examined for three protocols: CT head, CT angiography (CTA), and CT perfusion (CTP), respectively. Following installation of adaptive iterative dose reduction (AIDR) 3D software, tube current was lowered in consecutive cycles, in a stepwise manner and effective radiation doses measured at each step.

Results:

Baseline effective radiation doses for CT head, CTA and CTP were 1.80, 3.60 and 3.96 mSv, at currents of 300, 280 and 130–150 mA, respectively. Using AIDR 3D and final reduced currents of 160, 190 and 70–100 mA for CT head, CTA and CTP gave effective doses of 1.29, 3.18 and 2.76 mSv, respectively.

Conclusion:

We demonstrated that satisfactory reductions in the effective radiation dose for CT head (28.3%), CTA (11.6%) and CTP (30.1%) can be achieved without sacrificing diagnostic image quality. We have also shown that iterative reconstruction techniques such as AIDR 3D can be effectively used to help reduce effective radiation dose. The dose reductions were performed within a short period and can be easily achievable, even in busy departments.
Meaningful work as realization and justification
Authors: Lepisto Douglas A. , Pratt Michael G.
Published: June 2016

We review and develop two alternative conceptualizations of meaningful work: a predominant perspective we label realization and an underdeveloped, yet critical, perspective we label justification. We develop each conceptualization by identifying the core problem meaningful work is thought to address and accompanying solutions. Next, we build from this distinction to propose a research agenda that advances scholarly understanding of meaningful work from a justification perspective. Through building this research agenda, we elevate scholarly understanding on meaningful work by illuminating new foci for research, highlighting the relevance of social-cultural mechanisms, and suggesting alternative outcomes.
Sinonasal aspergillosis in a British Shorthair cat in the UK
Authors: Tamborini Alice , Robertson Elise , Talbot Jessica J , Barrs Vanessa R
Published: June 2016

Case summary A 13-year-old, castrated male, British Shorthair cat presented for investigation of chronic, intermittent, bilateral epistaxis and stertor. CT revealed severe asymmetric bilateral intranasal involvement with extensive turbinate lysis, increased soft tissue attenuation and lysis of the sphenopalatine bone and cribriform plate. On retroflexed pharyngoscopy, a plaque-like mass occluded the choanae. Rostral rhinoscopic examination revealed extensive loss of nasal turbinates, necrotic tissue and mucosal fungal plaques in the left nasal cavity. The right nasal cavity was less severely affected. The nasal cavities were debrided extensively of plaques and necrotic tissue. Aspergillus fumigatus was isolated on fungal culture, and species identity was confirmed using comparative sequence analysis of the partial β-tubulin gene. On histopathology of nasal biopsies, there was ulcerative lymphoplasmacytic and neutrophilic rhinitis, and fungal hyphae were identified on nasal mucosa, consistent with a non-invasive mycosis. The cat was treated with oral itraconazole after endoscopic debridement, but signs relapsed 4.5 months from diagnosis. Residual left nasal fungal plaques were again debrided endoscopically and oral posaconazole was administered for 6 months. Fourteen months from diagnosis, the cat remains clinically well with mild intermittent left nasal discharge secondary to atrophic rhinitis.

Relevance and novel information This is the first case of rhinoscopically confirmed sinonasal aspergillosis to be diagnosed in a cat in the UK. Endoscopic confirmation of resolution of infection is useful in cases where mild nasal discharge persists after treatment.
Mechanisms of platelet-mediated liver regeneration
Authors: Lisman Ton , Porte Robert J.
Published: June 2016

Platelets have multiple functions beyond their roles in thrombosis and hemostasis. Platelets support liver regeneration, which is required after partial hepatectomy and acute or chronic liver injury. Although it is widely assumed that platelets stimulate liver regeneration by local excretion of mitogens stored within platelet granules, definitive evidence for this is lacking, and alternative mechanisms deserve consideration. In-depth knowledge of mechanisms of platelet-mediated liver regeneration may lead to new therapeutic strategies to treat patients with failing regenerative responses.

Published: June 2016

Purpose

To study the outcome of histologic transformation (HT) in a large prospective cohort of patients with follicular lymphoma (FL) who previously responded to immunochemotherapy.

Patients and Methods

After a median 6-year follow-up of 1,018 randomly assigned patients from the PRIMA trial, disease progression was observed in 463 patients, 194 of whom had histologic documentation.

Results

Forty patients had histology consistent with HT, and 154 had untransformed FL (median time to recurrence, 9.6 v 22.8 months, respectively; P = .018). Thirty-seven percent of biopsies performed during the first year of follow-up showed HT corresponding to 58% of all HTs. Altered performance status, anemia, high lactate dehydrogenase level, “B” symptoms, histologic grade 3a, and high Follicular Lymphoma International Prognostic Index scores at diagnosis were identified as HT risk factors. Response (complete v partial) to immunochemotherapy or rituximab maintenance had no impact on the risk of HT. After salvage treatment, patients with HT had less frequent complete response (50.3% v 67.4%; P = .03) and more disease progression (28.2% v 9.6%; P < .001) than patients without HT. Estimated overall survival for the patients with HT was poorer (median, 3.8 v 6.4 years; hazard ratio, 3.9; 95% CI, 2.2 to 6.9). Autologous stem cell transplantation improved the outcomes of patients with HT (median overall survival, not reached v 1.7 years) but not of patients with persistent FL histology.

Conclusion

HT in patients with FL who previously responded to immunochemotherapy is an early event associated with a poor outcome that may deserve intensive salvage with autologous stem cell transplantation. These data emphasize the necessity for biopsy at the first recurrence of FL.

Published: June 2016

Purpose

The Medical Research Council Adjuvant Gastric Infusional Chemotherapy (MAGIC) trial established perioperative epirubicin, cisplatin, and fluorouracil chemotherapy as a standard of care for patients with resectable esophagogastric cancer. However, identification of patients at risk for relapse remains challenging. We evaluated whether pathologic response and lymph node status after neoadjuvant chemotherapy are prognostic in patients treated in the MAGIC trial.

Materials and Methods

Pathologic regression was assessed in resection specimens by two independent pathologists using the Mandard tumor regression grading system (TRG). Differences in overall survival (OS) according to TRG were assessed using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate analyses using the Cox proportional hazards method established the relationships among TRG, clinical-pathologic variables, and OS.

Results

Three hundred thirty resection specimens were analyzed. In chemotherapy-treated patients with a TRG of 1 or 2, median OS was not reached, whereas for patients with a TRG of 3, 4, or 5, median OS was 20.47 months. On univariate analysis, high TRG and lymph node metastases were negatively related to survival (Mandard TRG 3, 4, or 5: hazard ratio [HR], 1.94; 95% CI, 1.11 to 3.39; P = .0209; lymph node metastases: HR, 3.63; 95% CI, 1.88 to 7.0; P < .001). On multivariate analysis, only lymph node status was independently predictive of OS (HR, 3.36; 95% CI, 1.70 to 6.63; P < .001).

Conclusion

Lymph node metastases and not pathologic response to chemotherapy was the only independent predictor of survival after chemotherapy plus resection in the MAGIC trial. Prospective evaluation of whether omitting postoperative chemotherapy and/or switching to a noncross-resistant regimen in patients with lymph node-positive disease whose tumor did not respond to preoperative epirubicin, cisplatin, and fluorouracil may be appropriate.
T-DM1 Activity in Metastatic Human Epidermal Growth Factor Receptor 2–Positive Breast Cancers That Received Prior Therapy With Trastuzumab and Pertuzumab

Published: June 2016

Purpose

Ado-trastuzumab emtansine (T-DM1) is currently approved for treatment in patients with human epidermal growth factor receptor 2 (HER2)–positive, metastatic breast cancer (MBC) who previously received trastuzumab and a taxane. However, there are no data on the activity of T-DM1 in patients who received prior pertuzumab, which is now included as standard first-line therapy. The goal of this study was to assess the efficacy of T-DM1 in routine clinical practice in a contemporary patient population that received both prior trastuzumab and pertuzumab.

Patients and Methods

We identified all patients with HER2-positive MBC who received T-DM1 after trastuzumab and pertuzumab between March 1, 2013, and July 15, 2015, via electronic pharmacy records and departmental databases at three institutions: MD Anderson Cancer Center, Smilow Cancer Hospital at Yale, and The James Cancer Hospital at the Ohio State University. We reviewed medical records of each case to confirm treatment sequencing and outcome.

Results

Of patients, 82 were identified and 78 were available for outcome analysis; 32% received T-DM1 as first- and second-line line therapy, and 48% received it as fourth-line treatment or later. Rate of prolonged duration on therapy, defined as duration on therapy ≥ 6 months, was 30.8% (95% CI, 20.6% to 41.1%), and tumor response rate was 17.9% (95% CI, 9.4% to 26.4%). Median duration on therapy was 4.0 months (95% CI, 2.7 to 5.1; range, 0 to 22.5 months). T-DM1 was discontinued for disease progression in 84% of patients and for toxicity in 10%.

Conclusion

Tumor response rates were lower than in prior reports of trastuzumab-resistant, HER2-positive MBC, but one third of patients received therapy with T-DM1 for ≥ 6 months, which suggests a clinically relevant benefit in patients who received prior pertuzumab.
Butyrylcholinesterase Deficiency Promotes Adipose Tissue Growth and Hepatic Lipid Accumulation in Male Mice on High-Fat Diet
Authors: Chen Vicky Ping , Gao Yang , Geng Liyi , Stout Michael B. , Jensen Michael D. , Brimijoin Stephen
Published: June 2016

Despite numerous reports of relationships between weight gain and butyrylcholinesterase (BChE), this enzyme's role in the genesis of obesity remains unclear, but recent research points to strong links with ghrelin, the “hunger hormone.” The availability of BChE knockout (KO) mice provides an opportunity to clarify the causal relationship between BChE and obesity onset. We now find that young KO mice have abnormally high plasma ghrelin levels that slowly decline during long-term high-fat feeding and ultimately drop below those in wild-type mice. On such a diet, the KO mice gained notably more weight, more white fat, and more hepatic fat than wild-type animals. In addition to a greater burden of hepatic triglycerides, the livers of these KO mice show distinctly higher levels of inflammatory markers. Finally, their energy expenditure proved to be lower than in wild-type mice despite similar activity levels and increased caloric intake. A gene transfer of mouse BChE with adeno-associated virus vector restored nearly all aspects of the normal phenotype. Our results indicate that BChE strongly affects fat metabolism, has an important impact on fat accumulation, and may be a promising tool for combating obesity.
Phosphoinositide signaling in plant development
Authors: Heilmann Ingo
Published: June 2016

The membranes of eukaryotic cells create hydrophobic barriers that control substance and information exchange between the inside and outside of cells and between cellular compartments. Besides their roles as membrane building blocks, some membrane lipids, such as phosphoinositides (PIs), also exert regulatory effects. Indeed, emerging evidence indicates that PIs play crucial roles in controlling polarity and growth in plants. Here, I highlight the key roles of PIs as important regulatory membrane lipids in plant development and function.
Ten years of induced pluripotency: from basic mechanisms to therapeutic applications
Authors: Karagiannis Peter , Eto Koji
Published: June 2016

Ten years ago, the discovery that mature somatic cells could be reprogrammed into induced pluripotent stem cells (iPSCs) redefined the stem cell field and brought about a wealth of opportunities for both basic research and clinical applications. To celebrate the tenth anniversary of the discovery, the International Society for Stem Cell Research (ISSCR) and Center for iPS Cell Research and Application (CiRA), Kyoto University, together held the symposium ‘Pluripotency: From Basic Science to Therapeutic Applications’ in Kyoto, Japan. The three days of lectures examined both the mechanisms and therapeutic applications of iPSC reprogramming. Here we summarize the main findings reported, which are testament to how far the field has come in only a decade, as well as the enormous potential that iPSCs hold for the future.
The closed spiracle phase of discontinuous gas exchange predicts diving duration in the grasshopper, Paracinema tricolor
Authors: Gudowska Agnieszka , Boardman Leigh , Terblanche John S.
Published: June 2016

The discontinuous gas exchange (DGE) pattern of respiration shown by many arthropods includes periods of spiracle closure (C-phase) and is largely thought to serve as a physiological adaptation to restrict water loss in terrestrial environments. One major challenge to this hypothesis is to explain the presence of DGE in insects in moist environments. Here, we show a novel ecological correlate of the C-phase, namely diving behaviour in mesic Paracinema tricolor grasshoppers. Notably, maximal dive duration is positively correlated with C-phase length, even after accounting for mass scaling and absolute metabolic rate. Here, we propose that an additional advantage of DGE may be conferred by allowing the tracheal system to act as a sealed underwater oxygen reservoir. Spiracle closure may facilitate underwater submersion, which in turn, may contribute to predator avoidance, the survival of accidental immersion or periodic flooding and aid exploiting underwater resources.
Differential sex-specific walking kinematics in leghorn chickens (Gallus gallus domesticus) selectively bred for different body size
Authors: Rose Kayleigh A. , Codd Jonathan R. , Nudds Robert L.
Published: June 2016

The differing limb dynamics and postures of small and large terrestrial animals may be mechanisms for minimising metabolic costs under scale-dependent muscle force, work and power demands; however, empirical evidence for this is lacking. Leghorn chickens (Gallus gallus domesticus) are highly dimorphic: males have greater body mass and relative muscle mass than females, which are permanently gravid and have greater relative intestinal mass. Furthermore, leghorns are selected for standard (large) and bantam (small) varieties and the former are sexually dimorphic in posture, with females having a more upright limb. Here, high-speed videography and morphological measurements were used to examine the walking gaits of leghorn chickens of the two varieties and sexes. Hind limb skeletal elements were geometrically similar among the bird groups, yet the bird groups did not move with dynamic similarity. In agreement with the interspecific scaling of relative duty factor (DF, proportion of a stride period that a foot has ground contact) with body mass, bantams walked with greater DF than standards and females with greater DF than males. Greater DF in females than in males was achieved via variety-specific kinematic mechanisms, associated with the presence/absence of postural dimorphism. Females may require greater DF in order to reduce peak muscle forces and minimize power demands associated with lower muscle to reproductive tissue mass ratios and smaller body size. Furthermore, a more upright posture observed in the standard, but not bantam, females, may relate to minimizing the work demands of being larger and having proportionally larger reproductive volume. Lower DF in males relative to females may also be a work-minimizing strategy and/or due to greater limb inertia (due to greater pelvic limb muscle mass) prolonging the swing phase.

Published: June 2016

Insoluble hierarchical polybithiophene/poly(ethylenedioxythiophene) thin films with a double-layered structure were prepared on an indium tin oxide transparent electrode by sequential electrochemical polymerization. The formation of the hierarchical structure was supported by the transmission absorption spectra and Raman scattering spectra of the double-layered polythiophene thin films. In the presence of residual oxygen as an electron acceptor, light irradiation on the polythiophene-modified electrodes generated stable cathodic photocurrents. A broad peak at approximately 440 nm corresponding to the absorption of neutral polythiophene was observed in the incident photon to current conversion efficiency profile of the polybithiophene/poly(ethylenedioxythiophene)-modified electrode. The photocurrent density of the polybithiophene/poly(ethylenedioxythiophene)-modified electrode was higher than that of the poly(ethylenedioxythiophene)-modified electrode.

Τα αποτελέσματα της έρευνας επισημαίνουν την πολλαπλότητα των πεδίων στα οποία μπορούν τα συναισθήματα να εκταθούν, καθώς και τη σπουδαιότητα των ερμηνειών που αποδίδουν οι φοιτητές σε σχέση με τη συγκεκριμένη μεθοδολογία μάθησης. Τα ζητήματα κοινωνικής και συναισθηματικής επικοινωνίας και επαφής αναδεικνύονται ως κρίσιμης σημασίας στη διερεύνηση των συναισθημάτων για την εμπειρία της εξ αποστάσεως μάθησης. Γενικά, τα ευρήματα της έρευνας αυτής υποστηρίζουν ότι η όσον το δυνατό συντομότερη εξοικείωση των σπουδαστών με την εξ αποστάσεως μεθοδολογία, η ενίσχυση της ποιοτικής επικοινωνίας με τους συμφοιτητές και τους καθηγητές και ο κατάλληλος προγραμματισμός και σωστή διαχείριση του χρόνου, είναι παράγοντες που συντελούν στη μείωση των αρνητικών συναισθημάτων.

Η παρούσα εργασία μελετά το ερώτημα εάν η τεχνολογία των Haptics (συσκευές απτικής ανάδρασης που επιτρέπουν στον χρήστη εικονικά να αγγίζει αντικείμενα και να αισθάνεται δυνάμεις) θα μπορούσε να ενσωματωθεί αποτελεσματικά στη διαδικασία διδασκαλίας στα σχολεία, καθώς επίσης και εάν αυτή η τεχνολογία θα μπορούσε να χρησιμοποιηθεί για να βελτιώσει την κατανόηση ορισμένων επιστημονικών εννοιών. Στα πλαίσια ενός IST ευρωπαϊκού προγράμματος με το ακρωνύμιο MUVII, μια νέα Haptic συσκευή σχεδιάστηκε ειδικά για εκπαιδευτικούς σκοπούς και κατασκευάσθηκε ένα πρωτότυπό της. Η συσκευή αυτή σχεδιάστηκε μετά από τη λεπτομερή μελέτη και εκτίμηση των εκπαιδευτικών αναγκών. Κατά τη διάρκεια αυτής της διαδικασίας, οι σημαντικότερες παράμετροι των απαιτήσεων των χρηστών καταγράφηκαν, και η λειτουργικότητα του τελικού προϊόντος συζητήθηκε με μια ομάδα εκπαιδευτικών εμπειρογνωμόνων, η οποία περιελάμβανε και δασκάλους. Αυτές οι απαιτήσεις μετασχηματίστηκαν σε προδιαγραφές για ένα σύστημα μεγάλης κλίμακας, αποκαλούμενο Interactive Kiosk Demonstrator (IKD), δηλαδή το «κιόσκι» επίδειξης. Ο στόχος του ΙKD ήταν να επιδειχθούν καινοτόμοι τρόποι αλληλεπίδρασης ανθρώπου-μηχανής, σε ένα ολοκληρωμένο περιβάλλον εικονικής πραγματικότητας που θα περιλάμβανε, τρισδιάστατη εικόνα, καινοτόμο τρισδιάστατο ψηφιακό ήχο και απτική ανάδραση (αίσθηση δυνάμεων, ροπών και αφής). Για το περιβάλλον του IKD σχεδιάστηκαν και υλοποιήθηκαν νέες εξειδικευμένες εκπαιδευτικές εφαρμογές, που εστιάζουν ειδικά στην εκπαίδευση θετικών επιστημών. Για τον σχεδιασμό αυτών των εφαρμογών οι εκπαιδευτικές ανάγκες των χρηστών αναλύθηκαν λεπτομερώς και αξιολογήθηκαν. Οι εφαρμογές αυτές χρησιμοποιήθηκαν και δοκιμάστηκαν από μαθητές διαφορετικών ηλικιών και τους δασκάλους τους, για μια περίοδο μεγαλύτερη των τριών μηνών, προκειμένου να διαπιστωθούν τα οφέλη και τα μειονεκτήματα της Haptic συσκευής καθώς επίσης και των εκπαιδευτικών εφαρμογών. Μερικά αξιοσημείωτα αποτελέσματα προήλθαν από τους ίδιους τους χρήστες (με την συμπλήρωση ειδικών ερωτηματολογίων), τα οποία υποστηρίζουν την άποψη ότι οι Haptic συσκευές μπορούν να είναι σημαντικά επωφελείς στην εκπαίδευση των μαθητών σε όλες τις βαθμίδες.

Η εργασία αναφέρεται στον παιδαγωγικό σχεδιασμό μίας σύνθετης διδακτικής παρέμβασης με τη δημιουργία ενός καινοτόμου, ομαδοσυνεργατικού μαθησιακού περιβάλλοντος, που περιελάμβανε τηλεδιδασκαλία, αλλά και τηλεσυνεργασία1 του οποίου τα αποτελέσματα και οι διαδικασίες διερευνήθηκαν (με τη μεθοδολογία της ποιοτικής εκπαιδευτικής έρευνας) ως προς: α) το ψυχοκοινωνικό κλίμα της τάξης, β) την επίδοση και το επίπεδο της γνωστικής ανάπτυξης των μαθητών, καθώς και γ) την ανάπτυξη της παιδαγωγικής εμπειρίας των συμμετεχόντων εκπαιδευτικών. Με βάση τη μεθοδολογία του προγράμματος «ΟΔΥΣΣΕΑΣ»2 (Anastasiades, 2003) σχεδιάστηκε και υλοποιήθηκε ένα διδακτικό πλαίσιο, το οποίο όμως εστίασε περισσότερο στο ανώτερο επίπεδο της τηλεσυνεργασίας και σε διερευνητικές στρατηγικές με υιοθέτηση της μεθοδολογίας των κοινοτήτων μάθησης3 (Dillenbourg et al., 1995), που λειτουργούσαν τόσο μέσα στην τάξη, όσο και σε συνεργασία με αδελφοποιημένες ομάδες μαθητών από απομακρυσμένα σχολεία, στο πλαίσιο της κοινωνικο-εποικοδομιστικής και κριτικής - χειραφετικής προσέγγισης και της ομαδοσυνεργατικής στρατηγικής (Ράπτης και Ράπτη, 2007).

Blended Collaborative Learning for Action Research Training
Authors: Avgerinou Maria D.
Published: June 2016

This action research study investigated the application and use of a blended collaborative learning model as a vehicle for developing in-service teachers’ action research skills in afield-based Master’s program. It also explored the roles of the instructor through the lens of the ‘four hats’ metaphor (Bonk et al., 2001). Research results endorsed the tremendous potential of both the collaborative and blended aspects of the selected instructional approach towards the creation of an interactive community of learners, as well as the development of deeply reflective thinking skills. From the course design perspective, this instructional approach facilitated the transformation of an action research training course to what Laurillard (2002) calls the “reflective practicum”. For this transition to occur, three highly significant conditions need be in place and work in parallel, namely the students’ own motivation and drive to achieve professional growth as opposed to those students that just wanted to complete the degree; as well as a positive student-instructor relationship, and the instructor’s continuous support, input and guidance.Key words: Blended Learning, Action Research, CMC, Collaborative Learning, Higher Education
Critical issues in the Supervision of Post-Graduate Dissertations in Distance Education Environments
Authors: Quan-Baffour Kofi Poku , Vambe Maurice Taonezvi
Published: June 2016

The main aim of this paper to identify, explain and advance as best practice, the principles of an alternative framework of postgraduate supervision in the context of distance education. This framework, we describe as Dynamic facilitation. Thepaper starts with a critique of the African Union Commission Plan of Action of the Second Decade for Education in Africa (2006-2015), highlighting the document’s unfortunate silence on the role of distance education in Africa’s Higher education. Wesuggest that this silence is due to African educationists’ reliance on old theories of learning and supervising dissertations whose main limitations are their narrow definition of higher education as residential university, and also the dominance ascribed to the pedagogic role of supervisors in the Behaviourist and Cognitivetheories of learning. We critique these theories for their inherent limitations and proceed to suggest that the context of distance education has its unique features and particularities that must be robustly engaged with, in the areas of learning and supervising of postgraduate dissertations. We then propose ‘dynamic facilitation’ as a type of supervision suited to distance education contexts. Our basic argument is that dynamic facilitation empowers postgraduate students because it allows for their initiative in generating new knowledge systems. We conclude by suggesting that dynamic facilitation takes into account the ‘distance-ness’ between supervisor and thesupervised; it integrates methods of assessment ranging from the main dissertation, to continual self-reflective assessment achieved through maintaining journal notes on work done and portfolio of the supervised’s experience during the process ofsupervision.Key words: Supervision, Distance Education, Post-Graduate, Critical, Dissertation, Context, Dynamic facilitation.
Επικοινωνία Καθηγητή –Συμβούλου και φοιτητών στις Σπουδές από απόσταση: Απόψεις φοιτητών στο πλαίσιο της Θ.Ε.ΕΚΠ65 του Ε.Α.Π.

Published: June 2016

Η αμφίδρομη επικοινωνία μεταξύ φοιτητή και διδάσκοντα και το  καλά σχεδιασμένο εκπαιδευτικό υλικό  αποτελούν τους σημαντικότερους παράγοντες για την επιτυχία ενός προγράμματος εξΑΕ που στοχεύει στο να οδηγήσει τον εκπαιδευόμενο σε μία ευρετική πορεία της γνώσης.Μέσω της αμφίδρομης επικοινωνίας ο διδάσκων διευκολύνει την αλληλεπίδραση και ενεργητική εμπλοκή του φοιτητή με το εκπαιδευτικό υλικό, κινητοποιεί το ενδιαφέρον του για εμβάθυνση στη μελέτη και συμβάλλει σημαντικά στη προσπάθεια του φοιτητή να διερευνήσει και να οικοδομήσει τις γνώσεις του. Επίσης, η ποιοτική επικοινωνία μεταξύ συμβούλου και φοιτητή λειτουργεί υποστηρικτικά με τη σαφή και επαρκή ανατροφοδότηση που πληροφορεί τον φοιτητή για την πρόοδό του και υπηρετεί τον εμψυχωτικό ρόλο του συμβούλου.Σε αυτήν την εργασία παρουσιάζεται η έρευνα που διεξήχθη στους φοιτητές της Θεματικής ενότητας ΕΚΠ65 (Ανοικτή και εξ Αποστάσεως Εκπαίδευση) του Ε.Α.Π.  Σκοπός της ήταν να διερευνηθούν οι απόψεις των φοιτητών σχετικά με τη συχνότητα, το αντικείμενο και τους τρόπους επικοινωνίας με τον διδάσκοντα, καθώς και οι απόψεις τους για τη συνεισφορά της επικοινωνίας αυτής στην ολοκλήρωση των σπουδών τους. Μέσα από τις απαντήσεις τους, θα προσπαθήσουμε να ορίσουμε το πλαίσιο της αποτελεσματικής επικοινωνίας μεταξύ φοιτητή και Κ.Σ. και να συνθέσουμε το προφίλ του επιτυχημένου Κ.Σ. σύμφωνα με τη γνώμη των φοιτητών.
Απόψεις των μεταπτυχιακών φοιτητών της Θεματικής Ενότητας ΕΚΠ 65 «Ανοικτή και εξ Αποστάσεως Εκπαίδευση» για το ρόλο και την αποστολή του Καθηγητή Συμβούλου στο ΕΑΠ

Published: June 2016

Οι απαιτούμενες δεξιότητες του Καθηγητή Συμβούλου (Κ.Σ) στην εξ Αποστάσεως Εκπαίδευση κατηγοριοποιούνται σε τρεις κύριες κατηγορίες: οργανωτικές, κοινωνικές και παιδαγωγικές δεξιότητες. Οι τρεις αυτές κατηγορίες δεξιοτήτων συνθέτουν το ρόλο του Κ.Σ του  ΕΑΠ, ο οποίος είναι να υποστηρίζει, να ενθαρρύνει, να αξιολογεί τους εκπαιδευόμενους σε όλη την διάρκεια των σπουδών τους. Η αξιολόγηση στην εκπαιδευτική διαδικασία και ιδιαίτερα η αξιολόγηση του Κ.Σ του ΕΑΠ ως παράγοντα της εκπαιδευτικής διαδικασίας είναι από τις πιο σημαντικές δραστηριότητες, που έχει στόχο τη βελτίωση του ίδιου του Κ.Σ και της εκπαιδευτικής διαδικασίας. Σκοπός της παρούσας εργασίας είναι να διερευνηθούν οι απόψεις των μεταπτυχιακών φοιτητών του ΕΑΠ, που παρακολουθούν την Θεματική Ενότητα ΕΚΠ 65 «Ανοικτή και εξ Αποστάσεως Εκπαίδευση», αναφορικά με τους άξονες και τα επιμέρους κριτήρια με βάση τα οποία θα μπορούσε να δομηθεί ένα πλαίσιο αποτίμησης του ρόλου και της αποστολής των Κ.Σ του ΕΑΠ.
