Recently, there has been growing interest in the use of ontology as a fundamental tool for representing domain-specific conceptual models to improve the semantics, accuracy, and relevance of domain users’ query results. Although the amount of data has grown steadily over the past decade, much data shares similar characteristics that can be captured by a foundational ontology. In this paper, we show how queries based on a foundational ontology can be evaluated and their performance measured. We also present a Foundational (...) Patterns benchmark to help select the most efficient triple memory and its layout. We evaluate the foundational benchmark with both generated and real datasets for state-of-the-art triple stores.

Magnetic resonance imaging is precise and efficient for interpreting the soft and hard tissues. Moreover, for the detailed diagnosis of varied diseases such as knee rheumatoid arthritis, segmentation of the knee magnetic resonance image is a challenging and complex task that has been explored broadly. However, the accuracy and reproducibility of segmentation approaches may require prior extraction of tissues from MR images. The advances in computational methods for segmentation are reliant on several parameters such as the complexity of the tissue, (...) quality, and acquisition process involved. This review paper focuses and briefly describes the challenges faced by segmentation techniques from magnetic resonance images followed by an overview of diverse categories of segmentation approaches. The review paper also focuses on automatic approaches and semiautomatic approaches which are extensively used with performance metrics and sufficient achievement for clinical trial assistance. Furthermore, the results of different approaches related to MR sequences used to image the knee tissues and future aspects of the segmentation are discussed. (shrink)

Trait emotional intelligence concerns people’s perceptions of their emotional functioning. Two studies investigated this construct in surgeons and comparison occupations. We hypothesized that trait EI profiles would differ both within surgical specialties as well as between them and other professions. Study 1 compared the trait EI profiles of four different surgical specialties. There were no significant differences amongst these specialties or between consultant surgeons and trainees in these specialties. Accordingly, the surgical data were combined into a single target sample that (...) was compared against samples of engineers, executives and senior managers, lawyers, junior military managers, nurses, and salespeople. Surgeons scored significantly higher on global trait EI than junior military managers, but lower than executives and senior managers, salespeople, and nurses. There were no significant differences vis-à-vis engineers or lawyers. A MANOVA confirmed a similar pattern of differences in the four trait EI factors. Global trait EI scores correlated strongly with single-question measures of job satisfaction and job performance in the surgical sample. These findings suggest that interventions to optimize the trait EI profiles of surgeons can be helpful in relation to job satisfaction, job performance, and overall psychological wellbeing. (shrink)

The rapid growth of covert activities via communications network brought about an increasing need to provide an efficient method for data hiding to protect secret information from malicious attacks. One of the options is to combine two approaches, namely steganography and compression. However, its performance heavily relies on three major factors, payload, imperceptibility, and robustness, which are always in trade-offs. Thus, this study aims to hide a large amount of secret message inside a grayscale host image without sacrificing its quality (...) and robustness. To realize the goal, a new two-tier data hiding technique is proposed that integrates an improved exploiting modification direction method and Huffman coding. First, a secret message of an arbitrary plain text of characters is compressed and transformed into streams of bits; each character is compressed into a maximum of 5 bits per stream. The stream is then divided into two parts of different sizes of 3 and 2 bits. Subsequently, each part is transformed into its decimal value, which serves as a secret code. Second, a cover image is partitioned into groups of 5 pixels based on the original EMD method. Then, an enhancement is introduced by dividing the group into two parts, namely k1 and k2, which consist of 3 and 2 pixels, respectively. Furthermore, several groups are randomly selected for embedding purposes to increase the security. Then, for each selected group, each part is embedded with its corresponding secret code by modifying one grayscale value at most to hide the code in a -ary notational system. The process is repeated until a stego-image is eventually produced. Finally, the χ2 test, which is considered one of the most severe attacks, is applied against the stego-image to evaluate the performance of the proposed method in terms of its robustness. The test revealed that the proposed method is more robust than both least significant bit embedding and the original EMD. Additionally, in terms of imperceptibility and capacity, the experimental results have also shown that the proposed method outperformed both the well-known methods, namely original EMD and optimized EMD, with a peak signal-to-noise ratio of 55.92 dB and payload of 52,428 bytes.

BackgroundEmergency separation of conjoined twins is performed when one twin is already dead or dying and threatens the survival of the other. The particular decision to perform an emergency separation of conjoined twins provides an ethical dilemma that needs special attention. Adding to the complexity of surgical and postsurgical management in emergency separation, ethical and sociocultural aspects further complicate decision-making.Case presentationFrom 1987 to 2022, 18 conjoined twin separations were performed in our centre. This paper describes three conjoined twin emergency separations. (...) In the first case of thoracoomphalopagus babies at nine days of age, one baby was diagnosed with necrotizing enterocolitis with frequent desaturation and seizures, and the other baby was healthy. Emergency separation was performed on the twelfth day of age; unfortunately, neither baby survived the surgery. In the second case, emergency separation was performed on the 110th day of life due to sepsis in one baby. The nonseptic twin passed away six hours after surgery, while the septic twin died 12 days after surgery due to wound dehiscence and abdominal sepsis. The third case was of an omphalopagus conjoined twin with a parasitic twin. The healthy baby was deemed nonviable but found to be healthy upon birth. Immediate emergency separation was performed at 2 h of age. The living baby survived the surgery but passed away two months later.ConclusionsWhen separation is deemed necessary to save one twin, it becomes difficult to apply standard ethical medical reasoning. The decision to separate results in most cases in very high-risk surgeries with poor outcomes during surgery and postsurgery. Compounded by the complexity of the case, sociocultural and religious aspects further add to the dynamics of decision-making. A multidisciplinary team must work together with a health ethics committee and navigate through this ethical conundrum with the patient and family at its decision-making centre to decide on the best plan of care.

Unlimited paid time off policies are currently fashionable and widely discussed by HR professionals around the globe. While on the one hand, paid time off is considered a key benefit by employees and unlimited paid time off policies are seen as a major perk which may help in recruiting and retaining talented employees, on the other hand, early adopters reported that employees took less time off than previously, presumably leading to higher burnout rates. In this conceptual review, we discuss the (...) theoretical and empirical evidence regarding the potential effects of UPTO on leave utilization, well-being and performance outcomes. We start out by defining UPTO and placing it in a historical and international perspective. Next, we discuss the key role of leave utilization in translating UPTO into concrete actions. The core of our article constitutes the description of the effects of UPTO and the two pathways through which these effects are assumed to unfold: autonomy need satisfaction and detrimental social processes. We moreover discuss the boundary conditions which facilitate or inhibit the successful utilization of UPTO on individual, team, and organizational level. In reviewing the literature from different fields and integrating existing theories, we arrive at a conceptual model and five propositions, which can guide future research on UPTO. We conclude with a discussion of the theoretical and societal implications of UPTO. (shrink)

Sport is viewed as a multidimensional phenomenon. Most countries,including Muslim nations, invest heavily in sports to ensure the participationof their citizens both for recreational and competitive purposes. Indeed, theinvolvement of Muslim countries in significant multi-sport events such as theCommonwealth, the Asian, and the Olympic Games are inevitable. Therefore,a proper projection should be given to Muslim athletes as their participationreflects the identity and culture of Muslim civilizations. To date, the issue ofMuslim athlete’s involvement in sports from the notion of Islamization hasyet (...) to be elucidated by any scholar. This paper aims to scrutinize the sportssociology as an academic discipline in the Muslim majority society context.It also views the philosophy of sports participation and the dilemma facedby Muslims in sports under the light of al- Qur’ān, and Hadith. In obtainingrelevant information for this paper, we employed qualitative content analysisfrom various literature. In conclusion, this discourse of sport, Islam, and society has potentially triggered the new social movement that accommodated the needs of the Muslim community towards sports participation and physical activity.

The current paper addresses two methodological problems pertinent to the analysis of observer studies in nonverbal rapport and beyond. These problems concern: the production of standardized stimulus materials that allow for unbiased observer ratings and the objective measurement of nonverbal behaviors to identify the dyadic patterns underlying the observer impressions. We suggest motion capture and character animation as possible solutions to these problems and exemplarily apply the novel methodology to the study of gender and cultural differences in nonverbal rapport. We (...) compared a Western, individualistic culture with an egalitarian gender-role conception and a collectivistic culture with a more traditional gender role conceptions. Motion capture data were collected for five male and five female dyadic interactions in each culture. Character animations based on the motion capture data served as stimuli in the observation study. Female and male observers from both cultures rated the perceived rapport continuously while watching the 1 min sequences and guessed gender and cultural background of the dyads after each clip. Results show that masking of gender and culture in the stimuli was successful, as hit rates for both aspects remained at chance level. Further the results revealed high levels of agreement in the rapport ratings across gender and culture, pointing to universal judgment policies. A 2 × 2 × 2 × 2 ANOVA for gender and culture of stimuli and observers showed that female dyads were rated significantly higher on rapport across the board and that the contrast between female and male dyads was more pronounced in the Arab sample as compared to the German sample. nonverbal parameters extracted from the motion capture protocols were submitted to a series of algorithms to identify dyadic activity levels and coordination patterns relevant to the perception of rapport. The results are critically discussed with regard to the role of nonverbal coordination as a constituent of rapport. (shrink)

Virtual reality enables individuals to be exposed to naturalistic environments in laboratory settings, offering new possibilities for research in human neuroscience and treatment of mental disorders. We used VR to study psychological, autonomic and postural reactions to heights in individuals with varying intensity of fear of heights. Study participants were immersed in a VR of an unprotected open-air elevator platform in an urban area, while standing on an unstable ground. Virtual elevation of the platform elicited robust and reliable psychophysiological activation (...) including increased distress, heart rate, and electrodermal activity, which was higher in individuals suffering from fear of heights. In these individuals, compared with individuals with low fear of heights, the VR height exposure resulted in higher velocity of postural movements as well as decreased low-frequency body sway oscillations. This indicates that individuals with strong fear of heights react to heights with maladaptive rigidity of posture due to increased weight of visual input for balance control, while the visual information is less reliable at heights. Our findings show that exposure to height in a naturalistic VR environment elicits a complex reaction involving correlated changes of the emotional state, autonomic activity, and postural balance, which are exaggerated in individuals with fear of heights.

The selection of ‘good’ pictures has increasingly become a crucial factor when transmitting news to the recipients. Every day thousands of events are happening and millions of pictures are taken. By choosing photographs for newspapers and magazines, photographic editorial departments want to attract the recipients' attention, evoke emotions and get them to read their stories. But what exactly is a good picture that meets these expectations? Which criteria are decisive for selecting pictures and what effects of this selection can be (...) measured on the recipients' side? This article presents the results of a research project carried out at the University of Erfurt in 2008 and conducted in collaboration with the German weekly magazine stern. It deals with the selection and impact of press photography by introducing the concept ‘photo news factors’. Applying the traditional news value theory to pictures, photo news factors are defined as selection criteria that, on the part of the communicator, decide whether the press photos are worth publishing. Furthermore, they are assumed to exert an influence on the intensity of attention that a picture arouses. (shrink)

Very little attention has been given to understanding the commitment to service quality and desirable outcomes in the hotel industry. This study investigates the impact of directive and participative leadership on the frontline commitment to service quality through the mediation of knowledge sharing. This will eventually help us to generate the employees' commitment to service quality desirable behavior. The survey was distributed to 37 hotels. A total of 235 frontline employees participated in the survey. The study findings show that directive (...) leadership has a negative relationship with CSQ. On the other hand, participative leadership positively influences CSQ. Notably, knowledge sharing mediates between directive leadership, participative leadership, and commitment to service quality. There were positive linkages between commitment to service quality and desirable outcomes, job performance, and organizational citizenship behavior and negative relation to turnover intention.

Introduction Respecting the Patients’ Rights Charter leads to the demands of patients for their rights and the response of rehabilitation therapists by increasing their compliance. The present study aimed to compare the views of patients and rehabilitation therapists about the importance and extent of compliance with the Patients’ Rights Charter. Methods This cross-sectional study was conducted for 3 months on 114 patients and 55 therapists who were selected using the convenience sampling method. The data collection tools included a demographic information (...) form and the Justification and Practice of Patient Rights Questionnaire. The collected data were analyzed using descriptive statistics, independent t-test, paired t-test, and Pearson correlation coefficient. Results Mean scores of the importance of compliance with the Patients’ Rights Charter were 2.21 ± 0.40 and 2.31 ± 0.43 in the group of patients and therapists, respectively. Moreover, the mean scores of compliance with the Patients’ Rights Charter were 1.45 ± 0.48 and 1.53 ± 0.61 from the perspective of patients and therapists, respectively. There was no statistically significant difference between the views of patients and therapists on the importance and extent of compliance with the Patients’ Rights Charter. Discussion and Conclusion The importance of respecting the Patients’ Rights Charter from the perspective of patients and therapists was at a desirable level while the level of compliance with it from the perspective of both groups was moderate. It seems that more research is needed to explain the causes of this discrepancy and increase compliance with the Patients’ Rights Charter in rehabilitation clinics. (shrink)

Good agricultural practices certification schemes have been promoted to enhance agricultural sustainability. This study seeks to explain the adoption of GAP certification schemes through an analysis of the role of personal values in guiding such choice. It is a departure from approaches taken in previous studies in the area. Through the laddering interview technique of means-end chain analysis, a hierarchical value map was systematically schematized to illustrate the relationship between adoption of GAP, outcomes, and personal values driving the choice. The (...) personal values identified in this study cluster under the headings of “better life”, “religious responsibility”, “healthy life”, and “responsible farmer”. Amongst these, the main evidence pointed to the desire to have “better life” through the enhanced financial position that is perceived to arise as a consequence of GAP adoption as being of primary importance. These findings suggest that, while profit is not the sole end driver of adoptive behavior, GAP certification schemes have to be seen as lucrative and to enhance the goals of achieving core personal values. Other empirical information in this study also has significant policy implications. It is a key finding of this paper that effective promotions of GAP should be tailored and targeted at specific segments of the farmer population. (shrink)

The possibility of accomplishing sustainable objectives is largely connected to the management and flourishing of an organizational system which keeps human capital engaged and committed. Our study investigated the association of inspirational leadership and innovative communication with employee engagement and commitment under the lens of leader member exchange theory. Specifically, we emphasized the mediating role of mutual trust in connection to social sustainability facets. A survey of data from employees in the manufacturing sector of Yunnan, China was utilized to test (...) the hypothesized model. The study findings reported a significant association and came to the conclusion that a leader’s inspirational behavior coupled with innovative communication is a significant predictor of engagement and commitment in socially sustainable organizations. Moreover, mutual trust significantly mediated the relationship of innovative communication and inspirational leadership with employee engagement and commitment reaching the social perspective of sustainability. The current study added to the literature of sustainable organization by pointing out the social dimensions of sustainability. (shrink)

Fair trade has been researched extensively. However, our understanding of why consumers might be reluctant to purchase fair trade goods, and the associated potential barriers to the wider adoption of fair trade products, is incomplete. Based on data from 409 USA participants, our study demonstrates some of the psychological processes that underlie the rejection of fair trade products by conservatives. Our findings show that political conservatism affects fair trade perspective-taking and fair trade identity, and these latter two subsequently affect fair (...) trade purchase intention. The decrease in fair trade perspective-taking and fair trade identity are two psychological features that potentially shield conservatives from the appeals of fair trade products. We extend prior research on the effects of political ideology on consumption not only by demonstrating the predisposition of highly conservative consumers towards prosocial consumption, but also by showing the internal functioning of the conservative decision-making process. We further demonstrate that the effect of conservatism on fair trade purchase deliberation is moderated by age and income. Age reduces the negative effect of conservatism on fair trade perspective-taking, whereas income heightens the negative effect of conservatism on fair trade perspective-taking. Our results suggest that fair trade initiatives can target the conservative consumer segment in high-income countries with a greater chance of success when applying marketing strategies that make perspective-taking redundant and that aim at younger consumers with lower incomes.

Teacher competencies can be researched in many different ways. In the present article they are studied from the learner’s viewpoint. The article presents results of the extensive project “Teacher Education for New Competencies for the Knowledge Society and the Role of these Competencies in Educational Goal Attainment at School”, carried out at the Faculty of Arts of the University of Ljubljana, with the financial support of the Slovenian Ministry of Education and Sport. We present the results of the learner’s judgement (...) of the teacher’s didactic competencies. We formed a questionnaire with which we operationalised teacher competencies with the purpose of measuring the teacher’s efficiency of instruction. In order to achieve the goals of modern instruction it is important to engage both models: learner‐centred and teacher‐centred education. The research showed that elements of the traditional instruction model are more frequently used than the model that demands a changed learner role. (shrink)

This paper aims to examine the direct and indirect impact of ambient air pollution on employees’ performance. This study has used cross sectional survey design to collect the data from the outdoor employees of the pharmaceutical industry of Pakistan. The data were collected in time lags from 299. Partial least squares- structural equation modeling approach was applied to analyze the data. The results show that AAP has a significant negative impact on the employees’ performance, and anxiety partially mediates the association (...) between AAP and employees’ performance. This study reveals that AAP brings anxiety among outdoor employees, which in turn decreases their working performance. The implications, limitations, and future research directions are presented in the last section of this study. (shrink)

The influential stage of Internet of Things has reformed all fields of life in general but specifically with the emergence of artificial intelligence has drawn the attention of researchers into a new paradigm of life standard. This revolution has been accepted around the globe for making life easier with the use of intelligent devices such as smart sensors, actuators, and many other devices. AI-enabled devices are more intelligent and capable of doing a specific task which saves a lot of resources (...) and time. Different approaches are available in the existing literature to tackle diverse issues of real life based on AI and IoT systems. The role of decision-making has its own importance in the AI-enabled and IoT systems. In-depth knowledge of the existing literature is dire need of the research community to summarize the literature in effective way by which practitioners and researchers can benefit from the prevailing proofs and suggest new solutions for solving a particular problem of AI-enabled sensing and decision-making for the IoT system. To facilitate research community, the proposed study presents a systematic literature review of the existing literature, organizes the evidences in a systematic way, and then analyzes it for future research. The study reported the literature of the last 5 years based on the research questions, inclusion and exclusion criteria, and quality assessment of the selected study. Finally, derivations are drawn from the included paper for future research. (shrink)

This article proposes an analysis of changes implemented during Malaysia's Prime Minister Abdullah Ahmad Badawi's administration (20032003), which displayed bias against changes and introduced schemes to justify the systems it upheld. Transmutations wrought during Abdullah's tenure may have been neither substantial nor totalizing, but within the conservative paradigm which had long gripped national politics, Abdullah's deviations were significant nevertheless.

The aim of present paper is to introduce the concept of ‘expressive perception’ in Ernst Cassirer’s philosophical mythology. Having Cited Dorothy Emmet’s methodological objection, the author, by recalling Kantian aspect of Cassirer’s thought and referring to the concept of ‘expressive perception’, would make an attempt to reply on his part: according to Cassirer, this level of perceptive experience is the origin of the mythical form of thinking as a whole and, at the same time, is the original and irreducible altogether. (...) Thus, taking ‘mythical thought’ as an independent form of thinking, beside the ‘critical-empirical’ form of thinking, is, for one thing, completely cogent; for another, due to its dependency upon expressive form of perception, mythical thought would never be quite omitted, rather, keep living latently beneath the skin of mental life. In addition, author explains how much Cassirer owes, regarding to the concept of ‘expressive form of perception’, to Max Scheler. Avoiding to elaborate on Scheler’s detailed argument, Cassirer relies strongly on the consequences Scheler draws from his considerations in his work ‘Wesen und Formen der Sympathie’. Restating Scheler’s argument briefly should help in understanding Cassirer’s idea. (shrink)

This review summarizes the research on ethical decision-making from 2004 to 2011. Eighty-four articles were published during this period, resulting in 357 findings. Individual findings are categorized by their application to individual variables, organizational variables, or the concept of moral intensity as developed by Jones :366–395, 1991). Rest’s four-step model for ethical decision-making is used to summarize findings by dependent variable—awareness, intent, judgment, and behavior. A discussion of findings in each category is provided in order to uncover trends in the (...) ethical decision-making literature. A summary of areas of suggested future research is provided.

Conversational artificial intelligence (CAI) presents many opportunities in the psychotherapeutic landscape—such as therapeutic support for people with mental health problems and without access to care. The adoption of CAI poses many risks that need in-depth ethical scrutiny. The objective of this paper is to complement current research on the ethics of AI for mental health by proposing a holistic, ethical, and epistemic analysis of CAI adoption. First, we focus on the question of whether CAI is rather a tool or an (...) agent. This question serves as a framework for the subsequent ethical analysis of CAI focusing on topics of (self-) knowledge, (self-)understanding, and relationships. Second, we propose further conceptual and ethical analysis regarding human-AI interaction and argue that CAI cannot be considered as an equal partner in a conversation as is the case with a human therapist. Instead, CAI’s role in a conversation should be restricted to specific functions. (shrink)

Although much has been written about the nature of philosophy and how the discipline can be defined, little attention has been paid to the ways we develop the facility to reflect philosophically or why cultivating this ability is valuable. This article develops a conception of “philosophical sensitivity,” a perceptual capacity that facilitates our awareness of the philosophical dimension of experience. Based in part on Aristotle's notion of a moral perceptual capacity, philosophical sensitivity starts with most people's natural inclinations as children (...) to reflect about life's fundamental mysteries; when this capacity is cultivated with training over time, our attentiveness to the philosophical features of ordinary life becomes almost second nature. In much the same way an aesthetically sensitive person notices certain qualities of experience not readily perceptible by others, philosophical sensitivity involves the development of a particular way of seeing the world.

Critics of Aristotelian accounts of practical reasoning, in teaching and in other contexts, criticise phronesis for its rigidity and lack of imagination. This paper argues that phantasia, or imagination, helps us to develop a richer account of Aristotle’s phronesis. Two senses of phantasia, as producing images and as an interpretive faculty, are proposed here to be importantly involved in phronesis. By producing images that help in the selection of an end goal, and by having an interpretive faculty that helps to (...) compare competing possibilities, phantasia plays a crucial role in the practical reasoning process of phronesis.

The vast majority of studies on affective processes in reading focus on single words. The most robust finding is a processing advantage for positively valenced words, which has been replicated in the rare studies investigating effects of affective features of words during sentence or story comprehension. Here we were interested in how the different valences of words in a sentence influence its processing and supralexical affective evaluation. Using a sentence verification task we investigated how comprehension of simple declarative sentences containing (...) a noun and an adjective depends on the valences of both words. The results are in line with the assumed general processing advantage for positive words. We also observed a clear interaction effect, as can be expected from the affective priming literature: sentences with emotionally congruent words (e.g., The grandpa is clever) were verified faster than sentences containing emotionally incongruent words (e.g., The grandpa is lonely). The priming effect was most prominent for sentences with positive words suggesting that both, early processing as well as later meaning integration and situation model construction, is modulated by affective processing. In a second rating task we investigated how the emotion potential of supralexical units depends on word valence. The simplest hypothesis predicts that the supralexical affective structure is a linear combination of the valences of the nouns and adjectives (Bestgen, 1994 ). Overall, our results do not support this: The observed clear interaction effect on ratings indicate that especially negative adjectives dominated supralexical evaluation, i.e., a sort of negativity bias in sentence evaluation. Future models of sentence processing thus should take interactive affective effects into account. (shrink)
