Employee stress and the implication of high-power distance culture: empirical evidence from Nigeria’s employment terrain
No full textPurpose:
This paper explores the link between employee stress and the high-power distance (HPD) culture in Nigeria. The study context is the banking and manufacturing sectors in Nigeria, which have a history of exploitation, unconducive work environments to productivity, work-life imbalance, work overload, burnout and employee stress.
Design/methodology/approach:
Using a qualitative, interpretive methodology, this article adopts a thematic analysis of data drawn from semi-structured interviews with 24 managerial and non-managerial workers to explore the process by which Nigerian manufacturing and banking sectors' work (mal)practices go unchallenged, thereby triggering and exacerbating employees' stress levels.
Findings:
The study found that the high power distance culture promotes a servant-master relationship type, making it impossible for employees to challenge employers on issues relating to stressors such as work overload, unconducive work environments, work-life imbalance and burnout, thereby exacerbating their stress levels in a country in which stress has become a way of life.
Research limitations/implications:
Research on the relationship between employee stress and HPD culture is relatively underdeveloped. This article sheds light on issues associated with stressors in Nigeria's human resource management (HRM) and employment relations practices. The link between the inability of employees to challenge these stressors (which are consequences of an HPD culture) and increased employee stress has substantial implications for employment and work-related policies and practices in general. The study is constrained by the limited sample size, which inhibits the generalisation of its findings.
Originality/value:
The article adds to the scarcity of studies underscoring the relationship between high-power distance and the inability of employees to challenge work-related stressors as a predictor of employee stress and a mediator between workplace practices and employee stress, particularly in the emerging economies
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Weathering the Storm: Talent Management in Internationally Oriented Greek Small and Medium-Sized Enterprises
No full textThe file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Purpose – Based on a study of internationally oriented Greek small and medium-sized enterprises (SMEs), and using the lens of institutional theory, this article extends our understanding of the extent to which Greece’s institutional context influences talent management (TM). In so doing, we focused on key TM practices employed by SMEs to enhance and sustain TM: talent acquisition, development and retention. We also explore how these practices are shaped by the Greek institutional context.
Design/methodology/approach - Employing a multiple case-study approach, we conducted 18 interviews in six distinctive SMEs operating in north, central and southern Greece. The data was thematically analysed to identify patterns across all SMEs.
Findings - We found that unlike multinational corporations (MNCs), internationally oriented Greek SMEs adopt a more inclusive approach to TM practices as well as that the country’s institutional context presented important yet not deterministic hurdles. We also found that SMEs adopt an opportunistic approach to talent acquisition by utilising appropriate available sources to reach out for available talent. We provided evidence that SMEs adopt a hybrid approach to talent development in addressing talent scarcity. Finally, we reported that talent retention is significantly appreciated by SMEs, who offer a range of intrinsic and extrinsic incentives to retain their talented workforce.
Originality - In a context of reforms, we report on TM practice in internationally oriented Greek SMEs. We also add to the literature on TM in SMEs by providing evidence on the conceptualisation and management of global talent in this context

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.

A ±25A Versatile Shunt-Based Current Sensor with 10kHz Bandwidth and ±0.25% Gain Error from -40°C to 85°C Using 2-Current Calibration
No full textAccurate current sensing is critical in many industrial applications, such as battery management and motor control. Precise shunt-based current sensors have been reported with gain errors of less than 1% over the industrial temperature range (-40°C to 85°C) [1]–[4]. However, since they are intended for coulomb counting, their bandwidth is limited to a few tens of Hz, making them unsuitable for battery impedance or motor-current sensing. This paper presents a current sensor with a wide (10kHz) bandwidth and a tunable temperature compensation scheme (TCS), which allows it to be flexibly used with different types of shunts while maintaining high accuracy. A low-cost room-temperature calibration scheme is proposed to optimize gain flatness over temperature by exploiting the shunt's self-heating at large currents. Over the industrial temperature range and a ±25A current range, it achieves state-of-the-art gain error (±0.25%) with both low-cost PCB and stable metal-alloy shunts.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic InstrumentationMicroelectronic

Archivist, Archaeologist, Author and the Tactile Window
No full textThe idea that the predominant way of engaging with architecture is through vision is not uncommon but also not always the most appropriate given that buildings are also experienced through tactile interventions. This consequence that emphasises visual aesthetics in order to appreciate and understand architecture probably has much to do with the assumed but rather vaguely defined role of the architect as designer in the practice of architectural design. A resulting misapprehension is that architects designing for visual appreciation think that they are actually designing physical space for embodied tactile engagement.
This prioritisation of vision in the way architects think about and approach design is questioned through the design project of the Tactile Window in which the position of the architect is redefined through inhabiting the roles of archivist, archaeologist and author during the design process.
A 16th century portrait of Queen Elizabeth I known as the Ditchley portrait, currently on display at the National Portrait Gallery is used as the source from which the design of the Tactile Window is derived from and refers back to. Questioning the validity of vision as the sole means of engaging with the work, information about the portrait and working methods gathered from the three carefully chosen positions mentioned above are drawn on and applied to the making of this Tactile Window that becomes an alternative Ditchley portrait. Through exploring the hidden historical and current narratives of and in the existing portrait, the presence of the portrait is alluded to on an alternative physical site. Key to this are the working methods of an invented archival system of design reasoning, the unearthing of archaeological texts and assuming of authorship within the individual frameworks of the roles of archivist, archaeologist and author.
The redefined role of the architect as archaeologist takes onboard the unearthing of associated drawings and writings as well as the methods of organising and applying the recovered information to the system set up by the archivist. This analysis of the graphic and text based information is used to formulate historical narratives that are woven into the design project. Whereas traditional archaeology stresses on the study of a site from a site with quantifiable limits to the physical context, the notion of archaeological sites in this instance refers to the places where the stored information is unearthed. Through the careful process of archiving and analysing this information, a new site that is located within both the physical and historical contexts of interest is discovered. The author then draws upon the elements in the archival system that includes the findings of the archaeologist to construct the alternative Ditchley portrait in this new site of the Echoing Cedar, the result of which bears no visual resemblance to the existing work.
The Tactile Window is a reading of the Ditchley portrait in which information about and in the painting is transformed into a design proposal for an inhabited structure. The intended method of interaction with this alternative portrait is not merely restricted to vision but relies on engagement with the other senses. This experience is enhanced by the interplay with certain site conditions such as wind and rain in order to allude to specific aspects of the Ditchley portrait that are not visually apparent in the existing work.
In the processes of excavating, finding and revealing the hidden information to create this alternative portrait, the effects of the visuals afforded by the existing portrait inadvertently begin to fade as the validity of a single means of visual expression is questioned
