According to the Collingridge dilemma, technology is easy to control when its consequences are not yet manifest; once they appear, the technology is difficult to control. This article examines the development of keyboard layout design from the perspective of the Collingridge dilemma. For this purpose, unlike related studies that focus on a limited period of time, the history of keyboard development is explored from the invention of the typewriter and the QWERTY to brain–computer interfaces. Today, there is no mechanical problem (...) of the typewriter for which the QWERTY was designed. On the other hand, better layouts have been designed for various situations so far, that can be easily implemented especially on virtual keyboards, but QWERTY has not been replaced. The present study shows how various factors as heterogeneous engineering have shaped QWERTY, prevented the prevalence of superior layouts, and led to Lock-in. Then, unlike other studies related to the Collingridge dilemma, which provide a qualitative description of it, a quantitative description is proposed that helps to better understand the Collingridge dilemma and Lock-in. Finally, the case study of the QWERTY keyboard illustrates that the theory of human-technology co-construction can provide a more comprehensive explanation of technology development, while the Collingridge dilemma can better provide some details of technology development.

This study examined the interrelationships among selected cognitive characteristics of Iranian EFL learners including English self-efficacy, metacognitive awareness, and their test performance. For this purpose, a model was proposed based on empirical studies and was tested using structural equation modeling. Following this, two questionnaires were administrated to 200 Iranian EFL learners of two language institutes in Mashhad, Iran. Results of this study indicated that Iranian EFL learners perceived themselves self-efficacious. They were also metacognitively aware of their learning process. Correlation analysis (...) results showed that metacognitive awareness statistically correlated with English self-efficacy and foreign language test performance. It was found that English self-efficacy significantly correlated with foreign language test performance as well. The proposed SEM model adequately fitted the data. Results of the SEM indicated that self-efficacy was the strongest direct predictor of learners’ test performance. Metacognitive awareness directly affected learners’ English self-efficacy. It also indirectly affected test performance through affecting English self-efficacy. (shrink)

Ethical leadership can lead to preparing the ground for employee voice, highlighting employees’ creativity, and encouraging knowledge-sharing behavior in the organization. Thus, this study examines the impact of ethical leadership on organizational identity with the mediating role of employee voice in digital startups. However, previous studies investigating the relationship between ethical leadership and organizational identity disregarded the intervening role of employee voice in this relationship. A cross-sectional design using a sample of 137 managers of digital startups in science parks. Through (...) the PLS3 software, the results show that employees tend to discuss their work-related opinions and concerns more often if they consider their leaders trustworthy, and this can lead to competitive advantage and quick responses to environmental crises. According to the findings of this study, ethical leadership can prepare the ground for employee voice, highlight employees’ creativity, and encourage knowledge-sharing behavior in the organization. Hence, we suggest that leaders demonstrate personal integrity, openly receive employees’ ideas and recommendations, treat employees impartially, and attempt to maximize the benefits to their employees.

Background Moral distress is a common challenge among professional nurses when caring for their patients, especially when they need to make rapid decisions. Therefore, leaving moral distress unconsidered may jeopardize patient quality of care, safety, and satisfaction. Aim To estimate moral distress among nurses. Methods This systematic review and meta-analysis conducted systematic search in Scopus, PubMed, ProQuest, ISI Web of Knowledge, and PsycInfo up to end of February 2022. Methodological quality of included studies was assessed using the Newcastle Ottawa checklist. (...) Data from included studies were pooled by meta-analysis with random effect model in STATA software version 14. The selected key measure was mean score of moral distress total score with its’ 95% Confidence Interval was reported. Subgroup analyses and meta-regressions were conducted to identify possible sources of heterogeneity and potentially influencing variables on moral distress. Funnel plots and Begg’s Tests were used to assess publication bias. The Jackknife method was used for sensitivity analysis. Ethical consideration The protocol of this project was registered in the PROSPERO database under decree code of CRD42021267773. Results Eighty-six manuscripts with 19,537 participants from 21 countries were included. The pooled estimated mean score of moral distress was 2.55 on a 0–10 scale [95% Confidence Interval: 2.27–2.84, I2: 98.4%, Tau2:0.94]. Publication bias and small study effect was ruled out. Moral distress significantly decreased in the COVID-19 pandemic versus before. Nurses working in developing countries experienced higher level of moral distress compared to their counterparts in developed countries. Nurses' workplace (e.g., hospital ward) was not linked to severity of moral disturbance. Conclusion The results of the study showed a low level of pooled estimated score for moral distress. Although the score of moral distress was not high, nurses working in developing countries reported higher levels of moral distress than those working in developed countries. Therefore, it is necessary that future studies focus on creating a supportive environment in hospitals and medical centers for nurses to reduce moral distress and improve healthcare. (shrink)

In this study, the speed control of a DC motor with input delay and external disturbance is investigated. A delay-dependent memory state feedback robust predictor-based H ∞ controller that formerly has presented is utilized. Sufficient LMIs conditions provide the stabilizing gain of the predictor-based controller. The first-order model of a DC motor has been studied previously using PID and STA methods. However, in this paper, the delay-dependent robust H ∞ controller is used on both the first and second orders of (...) the DC motor. Finally, the predictor-based H ∞ controller is compared to the PID controller and the common H ∞ controller as well. The simulation results show that the proposed method has been more useful and efficient. (shrink)

A key factor for the acceptance of robots as regular partners in human-centered environments is the appropriateness and predictability of their behaviors, which depend partially on the robot behavior’s conformity to social norms. Previous experimental studies have shown that robots that follow social norms and the corresponding interactions are perceived more positively by humans than robots or interactions that do not adhere to social norms. However, the conducted studies only focused on the effects of social norm compliance in specific scenarios. (...) Therefore, this paper aims to guide further research studies by compiling how researchers in relevant research fields think the perception of robots and the corresponding interactions are influenced independently of a specific scenario if a robot’s behavior conforms to social norms. Additionally, this study investigates what characteristics and metrics constitute a good general benchmark to objectively evaluate the behavior of social robots regarding its conformity to social norms according to researchers in relevant research communities. Finally, the paper summarizes how the obtained results can guide future research toward socially aware robot behavior. (shrink)

Speaking about the state of the Hollywood film industry at the 2008 Academy Awards, the Oscars’ host – comedian Jon Stewart – made the following wry assessment: ‘Not all films did as well as Juno obviously. The films that were made about the Iraq War, let’s face it, did not do as well. But I’m telling you, if we stay the course and keep these movies in the theatres we can turn this around. I don’t care if it takes 100 (...) years. Withdrawing the Iraq movies would only embolden the audience. We cannot let the audience win.’ The films he is referring to include Home of the Brave (2006), In the Valley of Elah (2007) and Stop-Loss (2008) – all of which focus on the personal cost to American soldiers on their return to civilian life, as well as exposing the failure of the US invasion of Iraq at home and abroad. Despite their topical subject matter, these movies were, for the most part, commercial failures. This article seeks to investigate audience indifference (Jean Baudrillard claims a certain indifference is a fundamental consequence of the Western globalising ideology) to mainstream cinematic depictions of the post September 11 invasion of Iraq, via a consideration of the trauma and abjection depicted in these films. Baudrillard’s hypotheses on terrorism – as a symbolic challenge put forth by terrorism (embodied by the attack on the Twin Towers) – and the West’s incapacity to respond to it, forms the basis for our investigation of the limits of these films to incite and engage viewers. His writings offer a lens through which to consider how ‘terrorism’ operates symbolically, and fundamentally, the dilemmas this raises for a Western psyche grappling with how the ‘terrorist threat’ might be answered, engaged with, responded to.
