The article suggests approaches to improved communication when serving a child who is an immigrant to the U.S., calls for an increase in cross-disciplinary collaboration, and concludes with a suggested reading and resource list
Exploring Employee Engagement in a Global Context – The Example of Germany
This research aims to gain in-depth understanding of the views, conceptualisations, and
adaptions of Employee Engagement in Germany. While the empirical study focuses on
Germany, the literature review was based on the findings from rich Anglo-US sources and was
drawn from Human Resource Management, Human Resource Development, and Employee
Engagement literature. Here, the topic of Employee Engagement was of increasing interest in
academia, and to practitioners. Moreover, the limited literature on Employee Engagement
published in German and on Germany was also reviewed. The review considered different
perspectives on the phenomenon as well as emerging frameworks, and revealed that there
was no unified Employee Engagement definition, but rather different drivers and output factors
associated with the phenomenon. Furthermore, the author also reflected on potential German
equivalents of the untranslatable Employee Engagement term, including Mitarbeitermotivation,
for example. The social construction of the phenomenon according to literature was reviewed
and is presented along with its evolution and various measurement approaches. Finally, the
author reflected on cross-cultural and generational differences, as well as on the impact of
language on the term’s meaning as well as its role in human resources.
The empirical study itself used a multiple method approach, combining in-depth interviews and
a documentary method, to gather data on the understanding and establishment of Employee
Engagement in organisations in Germany. A pilot interview was conducted, followed by 18 indepth interviews with HR managers or equivalents from different industries, which contributed
rich detail concerning the interviewees’ understanding of the phenomenon and its adoption
and establishment by organisations. The documentary analysis supported the findings from
the primary research and provided additional insights into the organisational Employee
Engagement conceptualisation, which was primarily based on the implementation of (ad hoc)
initiatives to drive Employee Engagement. Nevertheless, the term itself was rarely used and
of less importance when it came to the phenomenon’s implementation. Instead, the interviews
showed that the organisations’ focus was on perceived drivers, such as development
possibilities, recognition, and appreciation as well as communication and transparency. This
was to ensure employees’ trust, identification, and contribution into their employer, in order to
achieve output factors including an increase in performance and loyalty as well as brand
identification and involvement. Similarities and variance between the empirical findings and
the literature review were presented and perspectives discussed. Here, definitional
inconsistencies were found both in the findings and the existing literature, still parallels were
identified with respect to an employee’s willingness to contribute cognitively, emotionally, and
physically. These findings were also underpinned and supported by the results of the author’s
documentary research. The organisations’ Employee Engagement approaches, especially
with respect to the implementation of benefits as a driver, were identified throughout the

documentary research. While the documentary analysis also revealed no consistent definition
for Employee Engagement, alternative approaches such as organisational culture and a strong
we-sentiment through associations with family and friends were shown to drive Employee
Engagement.
Finally, the contribution of the research is presented together with its implications for theory
and practice, but the study provides various insights, especially for practitioners of Employee
Engagement in large organisations in Germany. The author identified that most organisations
were using Employee Engagement in a piecemeal way and their individual reinventions of the
phenomenon to tackle individual or common challenges, such as the fight for talents and
loyalty, while only a few had established integrated Employee Engagement strategies which
relied on different components. At the same time, the study provides national and international
practitioners with insights into German-specific requirements and conditions, such as the
involvement of workers’ councils in ensuring safety and driving Employee Engagement.
Additionally, it contributes due to its use of a multiple method approach, as it enables
researchers to analyse both the espoused organisational viewpoint and the perceptions of
practitioners at the same time. The documentary analysis provides a rich set of data. Finally,
further research implications are outlined, emerging from limitations of the current study,
especially with respect to the long-term establishment of Employee Engagement in the
participating organisations, its measurability, and its adoption in German Mittelstand business

Longitudinal observation of the retinal nerve fibre layer in glaucoma patients treated with brimonidine combined with timolol or timolol alone
INTRODUCTION. The aim of the study was to evaluate the retinal nerve fibre layer (RNFL) thickness loss in primary open-angle glaucoma (POAG) patients treated topically with anti-glaucoma drops containing brimonidine and timolol combination or solely timolol.
MATERIALS AND METHODS. Retrospective case series study of patients with POAG diagnosis followed up for a five-year period. Inclusion criteria were fulfilled by a group of 98 patients consisting of 53 combination and 45 monotherapy treatments. Intraocular pressure (IOP) at the level of 21 mm Hg or below for each measurement was observed in 52 patients, while incidences of pressure above 21 mm Hg were measured in 46 patients. POAG diagnosis was based on standard optical coherence tomography, IOP, and visual field examinations.
RESULTS. Mean annual loss of RNFL thickness in the overall study group (if IOP levels are not taken into consideration) treated with timolol monotherapy was 1.8 ± 1.5 μm, while in group treated with brimonidine + timolol combination therapy it was 1.7 ± 1.5 μm (p > 0.05). In selected groups of patients with incidents of pressure rises, the mean annual loss of retinal nerve fibre layer thickness was 1.8 ± 1.6 and 1.9 ± 1.4 μm, respectively, for the monotherapy and combination therapy groups (p > 0.05). In the group of patients with no reported IOL rises, mean annual loss of RNFL thickness was 1.8 ± 0.9 and 1.1 ± 0.4 μm, respectively, for the monotherapy and combination therapy groups (p < 0.01). No significant differences were observed for the visual field mean deviation.
CONCLUSIONS. POAG patients with low values of IOP might achieve slower progression of RNFL thinning on brimonidine combined with timolol therapy.
Bootstrapping of Corneal Optical Coherence Tomography Data to Investigate Conic Fit Robustness
Background: Fitting of parametric model surfaces to corneal tomographic measurement
data is required in order to extract characteristic surface parameters. The purpose of this study was to
develop a method for evaluating the uncertainties in characteristic surface parameters using bootstrap
techniques. Methods: We included 1684 measurements from a cataractous population performed
with the tomographer Casia2. Both conoid and biconic surface models were fitted to the height
data. The normalised fit error (height—reconstruction) was bootstrapped 100 times and added to
the reconstructed height, extracting characteristic surface parameters (radii and asphericity for both
cardinal meridians and axis of the flat meridian) for each bootstrap. The width of the 90% confidence
interval of the 100 bootstraps was taken as uncertainty and quoted as a measure of the robustness
of the surface fit. Results: As derived from bootstrapping, the mean uncertainty for the radii of
curvature was 3 µm/7 µm for the conoid and 2.5 µm/3 µm for the biconic model for the corneal
front/back surface, respectively. The corresponding uncertainties for the asphericity were 0.008/0.014
for the conoid and 0.001/0.001 for the biconic. The respective mean root mean squared fit error was
systematically lower for the corneal front surface as compared to the back surface (1.4 µm/2.4 µm for
the conoid and 1.4 µm/2.6 µm for the biconic). Conclusion: Bootstrapping techniques can be applied
to extract uncertainties of characteristic model parameters and yield an estimate for robustness as an
alternative to evaluating repeat measurements. Further studies are required to investigate whether
bootstrap uncertainties accurately reproduce those from repeat measurement analysis
Quantitative measurement of pseudoexfoliation in the anterior segment of the eye performed in visible light
Introduction: Pseudoexfoliation syndrome (PEX) is a systemic disease involving the accumulation of pathological material deposits in the tissues of the anterior segment of the eye. The problem of modern ophthalmology is a quantitative assessment of the severity of PEX in the diagnosis and evaluation of the treatment progress in patients.Material and method: For the purposes of this study, 52 images of the anterior segment of the eye with the resolution of M Ă— N = 1280 Ă— 960 pixels were obtained in jpg format using the slit lamp CSO 450-SL. The patients were aged 50-80 and were recruited from Poland. All patients who participated in the study provided written informed consent after explanation of the nature and possible consequences of the study. The image analysis method proposed by the authors contains the calculation of the direction field, setting a straight perpendicular line passing through each pixel of the edge of the pupil, the calculation of the intersection of straight lines in order to determine the central point of the pupil position, the detection of the contour of PEX and the outer border of the iris with the use of the polar coordinate system. All analyzed parameters were set automatically with one exception parameter chosen manually depending on the slit lamp type.Results: A fully automatic measurement of PEX was carried out with the proposed method. Quantitative results enable to perform reproducible tests independently of the research centre. Owing to the image analysis method proposed by the authors, it is possible to obtain results in no more than 1 second on the Intel Core 2 Quad CPU 2.50 GHz with a measurement error below 3%. Other known methods of image analysis and processing that are compared in this paper give results with a greater error (4-35%) which depends on the degree of magnification (Ă—6, Ă—16, Ă—20) and are not fully automatic.Conclusions: The methods of image analysis and processing enable a quantitative, repeatable and automatic measurement of the severity and progress of PEX syndrome. They support medical diagnosis and automatic archiving of results
Comparative Study of Anterior Eye Segment Measurements with Spectral Swept-Source and Time-Domain Optical Coherence Tomography in Eyes with Corneal Dystrophies
Purpose. To compare anterior eye segment measurements and morphology obtained with two optical coherence tomography systems (TD OCT, SS OCT) in eyes with corneal dystrophies (CDs). Methods. Fifty healthy volunteers (50 eyes) and 54 patients (96 eyes) diagnosed with CD (epithelial basement membrane dystrophy, EBMD = 12 eyes; Thiel-Behnke CD = 6 eyes; lattice CD TGFBI type = 15 eyes; granular CD type 1 = 7 eyes, granular CD type 2 = 2 eyes; macular CD = 23 eyes; and Fuchs endothelial CD = 31 eyes) were recruited for the study. Automated and manual central corneal thickness (aCCT, mCCT), anterior chamber depth (ACD), and nasal and temporal trabecular iris angle (nTIA, tTIA) were measured and compared with Bland-Altman plots. Results. Good agreement between the TD and SS OCT measurements was demonstrated for mCCT and aCCT in normal individuals and for mCCT in the CDs group. The ACD, nTIA, and tTIA measurements differed significantly in both groups. TBCD, LCD, and FECD caused increased CCT. MCD caused significant corneal thinning. FECD affected all analyzed parameters. Conclusions. Better agreement between SS OCT and TD OCT measurements was demonstrated in normal individuals compared to the CDs group. OCT provides comprehensive corneal deposits analysis and demonstrates the association of CD with CCT, ACD, and TIA measurements
Anterior segment intraocular metallic foreign body causing chronic hypopyon uveitis
Intraocular foreign body (IOFB) is a common association of penetrating ocular trauma. Early diagnosis and removal of IOFBs especially if they are metallic is very important to determine further management and the final result of treatment. Missed IOFB may present in different clinical aspects that may limit its detection and symptoms may only become apparent after a prolonged period of time. We report a case of a missed metallic intraocular foreign body in the anterior chamber over a 2-year period without causing severe inflammatory reaction and presented with uveitis later. A 42-year-old man presented with a progressive blurring of vision, pain, photophobia, and redness in the left eye for 3 months. He had a history of traffic accident 2 years ago and he was accepted to intensive care unit for 3 days. Three months ago, in another center, he was admitted to hospital for 1 week and intravitreal antibiotics and medical treatment were given for pain, photophobia, and redness in his left eye. In five o’ clock meridian of the angle, there was an IOFB coated with hypopyon was observed under biomicrocopic magnification. Plain X-ray and computed tomography confirmed the foreign body in the left eye. After obtaining informed consent from the patient, the foreign body was removed under local anesthesia
