The Influence of Rewards for Creativity on Employee Creativity Performance

Abstract: Many scholars and practitioners are concerned with understanding how and when to motivate individuals to be more creative. We argue that the conflicting ideas may be due to differences between findings towards reward conditions and the situation in which rewards has to be offered. Hence, it is vital to portray in this study that motivating employees to be creative is important for many firms. Amount of literature shows that employee performance can be encouraged by extrinsic and intrinsic rewards in their everyday tasks. This paper, therefore, investigates these kinds of rewards and shows its effectiveness in attracting creative performance. It concluded by arguing that, human behaviors are stimulated by extrinsic motivations attained from works, which are capable to fulfill innate parts of individuals. Similarly, a person is intrinsically motivated when he or she found that the work is able to fulfill his or her psychological needs for the significant experience

Integrating Artificial Intelligence in a Morphology Course - An Analytical Study from University Students’ Perspectives

This paper attempts to scrutinize the attitudes and opinions of English as a Foreign Language (EFL) learners on the integration of artificial intelligence (AI) in a morphology course in higher education in Lebanon as a pedagogical tool in classroom contexts in providing learners with personalized learning paths centered on their needs and strengths, offering automated feedback on activities and assignments, supplying study resources and extra material, furnishing adaptive assessments, and most importantly, identifying common errors in students’ responses that allow instructors to acknowledge the learning gaps and tailor their teaching strategies accordingly. It also aims to determine the students’ perspectives on AI’s potent role in learning. In this exploratory study, a mixed-method design and a convenient sampling of participants were utilized. A total of 62 EFL students at the public university in Lebanon participated in the study. To describe and quantify their perceptions on integrating AI in a morphology course, an online survey including closed-ended and open-ended questions, and two focus group discussions were administered. The overall qualitative and quantitative analyses of the data indicated that Lebanese EFL students have positive attitudes towards integrating AI in a morphology course as a pedagogical tool and as a fundamental part of the teaching strategies in EFL higher education classes since it provides a good source of information and aids in the teaching and learning process; however, the findings also revealed the need to train teachers and students to use AI technologies keeping in mind the potent role of the instructor in class

Role of optical coherence tomography angiography to differentiate intraretinal microvascular abnormalities and retinal neovascularization in diabetic retinopathy

Objective: To assess proliferative diabetic retinopathy (PDR) and to describe the difference in angiographic representation of new vessels (NVs) and Intra retinal microvascular abnormalities (IRMA) on optical coherence tomography angiography (OCTA). Methods: A cross-sectional observational study was performed at ISRA Postgraduate Institute of Ophthalmology, Karachi, from March 2018 to September 2018. Forty-two eyes of 21 patients with history of diabetes mellitus (DM) were examined. Twenty-eight eyes with a clinical diagnosis of severe non proliferative diabetic retinopathy (NPDR) or proliferative diabetic retinopathy (PDR) according to early treatment diabetic retinopathy study (ETDRS) were included and evaluated using Swept source optical coherence tomography angiography (SS-OCTA). Then face wide field SS-OCTA images and co registered structural optical coherence tomography (OCT) with flow overlay were used to distinguish the features of IRMA and retinal NVs. Results: Forty-two eyes (21 patients) were examined clinically. Fourteen eyes had moderate NPDR, 15 had severe NPDR and 13 eyes had changes consistent with PDR. After clinical diagnosis, we included 28 eyes in our study based on inclusion criteria. These 28 eyes went through SS-OCTA evaluation and we observed 15 cases with PDR and 13 with severe NPDR changes. The OCTA and clinical diagnosis were similar except in 2 eyes, which is critical but not statically significant showing the importance of this noninvasive technology. Conclusions: Widefield OCTA can work as an alternative to fundus fluorescein angiography (FFA) in the diagnosis of diabetic retinopathy (DR). As it is a non-invasive and depth encoded technique so can be used frequently to monitor the retinal changes and their progression

On-Demand Routing for Urban VANETs using Cooperating UAVs

Vehicular ad hoc networks (VANETs) are characterized by frequent routing path failures due to the high mobility caused by the sudden changes of the direction of vehicles. The routing paths between two different vehicles should be established with this challenge in mind. Stability and connectedness are a mandatory condition to ensure a robust and reliable data delivery. The idea behind this work is to exploit a new reactive routing technique to provide regulated and well-connected routing paths. Unmanned Aerial Vehicles (UAVs) or what are referred to as drones can be both involved in the discovery process and be full members in these discovered paths in order to avoid possible disconnections on the ground when the network is sparsely connected. The different tests of this technique are performed based on NS-2 simulator and the outcomes are compared with those of related on-demand routing protocols dedicated for VANETs. Interesting results are distinguished showing a reduced end-to-end delay and a high delivery ratio, which proving that this heterogeneous communication between vehicles and UAVs is able to extend the network connectivity.Comment: 6 pages, 7 figures, conferenc

Smoking practices and nicotine dependence among adolescents in Pakistan

Objective: To find out the smoking prevalence and associated factors among in-school and out-of-school adolescents and their nicotine dependence.METHOD: The cross-sectional study was conducted from April to June 2008 comprising 1014 adolescents aged 12-18 years residing in two rural districts of Sindh and Punjab. Trained interviewers collected information from the adolescents regarding age, ethnicity, religion, occupation and education of parents, smoking behaviour, smoking history of family/friend, type of family system, number of siblings and place of residence. Statistical package Epi-Info version 6 was used to enter the data and analysis was performed by using SPSS version 12.Results: Overall smoking prevalence among the 1014 adolescents was 15.2%, with significant gender stratification (7.9% among girls versus 20.2% among boys). Of these, 50% were moderately nicotine dependent. However, the prevalence among in-school adolescents (14.6%) was not significantly different from out-of-school adolescents (16.1%). The factors associated with adolescents\u27 smoking were father\u27s illiteracy (adjusted odds ratio [OR] = 8.2), friend\u27s smoking (adjusted OR = 6.8), father\u27s smoking (adjusted OR = 5.4) and nuclear family setup (adjusted OR = 3.6). When explored for the first place of smoking, friends\u27 home was mentioned by majority of adolescents boys and girls.CONCLUSION: Although there was a significant difference found between the prevalence of smoking among adolescent males and females, but any difference among in-school and out-of-school adolescents smoking prevalence could not be established

U2RV: UAV-assisted reactive routing protocol for VANETs

When it comes to keeping the data routing robust and effective in Vehicular Ad hoc Networks (VANETs), stable and durable connectivity constitutes the keystone to ensure successful point-to-point communication. Since VANETs can comprise all kinds of mobile vehicles moving and changing direction frequently, this may result in frequent link failures and network partitions. Moreover, when VANETs are deployed in a city environment, another problem arises, that is, the existing obstructions (e.g., buildings, trees, hoppers, etc.) preventing the line-of-sight between vehicles, thus degrading wireless transmissions. Therefore, it is more complicated to design a routing technique that adapts to frequent changes in the topology. In order to settle all these problems, in this work, we design a flooding scheme that automatically reacts at each topology variation while overcoming the present obstacles while exchanging data in ad hoc mode with drones that are commonly called Unmanned Aerial Vehicles (UAVs). Also, the aim of this work is to explore well-regulated routing paths providing a long lifetime connectivity based on the amount of traffic and the expiration time of each discovered path, respectively. A set of experiments is carried out using simulation, and the outcomes are confronted with similar protocols based on a couple of metrics. The results clearly show that the assistance of UAVs to vehicles is capable to provide high delivery ratios and low delivery delays while efficiently extending the network connectivity

Surgical training in ophthalmology: Role of EyeSi in the era of simulation-based learning

Recent advancements in surgical training methods have escalated the need for simulators. The EyeSi simulation has played a major role in Ophthalmology training by providing opportunity to the novice residents to grasp the surgical steps of the procedure and master the skill by repeated attempts. Participants were assessed on single level of cataract module and their consecutive scores were assessed with each attempt. It was found that repetitive practice on simulator can help develop proficiency in the desired steps that can ultimately prepare the surgical trainees for real life surgery

High-energy ball milling technique for ZnO nanoparticles as antibacterial material

Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications. In this study, the high-energy ball milling (HEBM) technique was used to produce nanoparticles of ZnO from its microcrystalline powder. Four samples were ball milled for 2, 10, 20, and 50 hours, respectively. The structural and optical modifications induced in the ‘as synthesized’ nanomaterials were determined by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM), and photoluminescence emission spectra (PL). SEM and TEM results show a gradual decrease in particle size from around 600 to ∼30 nm, with increased milling time. The initial microstructures had random shapes, while the final shape became quite spherical. XRD analysis showed ZnO in a hexagonal structure, broadening in the diffracted peaks and going from larger to smaller particles along with a relaxation in the lattice constant c. The value of c was found to increase from 5.204 to 5.217 Å with a decrease in particle size (600 to ∼30 nm). PL result showed a new band at around 365 nm, whose intensity is found to increase as the particles size decreases. These remarkable structural and optical modifications induced in ZnO nanoparticles might prove useful for various applications. The increase in c value is an important factor for increasing the antibacterial effects of ZnO, suggesting that the HEBM technique is quite suitable for producing these nanoparticles for this purpose

Polatuzumab vedotin, rituximab, and bendamustine combination in relapsed or refractory diffuse large B-cell lymphoma: A real-world data from Turkey

Polatuzumab vedotin (Pola) with bendamustine and rituximab (BR) is a promising option for patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). We analyzed the data of 71 R/R DLBCL patients who had been treated with Pola-BR in the named patient program from March 2018 to April 2021 from 32 centers in Turkey. All patients received up to six cycles of Pola 1.8 mg/kg, rituximab 375 mg/m2 on day 1, and bendamustine 90 mg/m2 on days 1–2 of each cycle. Median age at Pola-BR initiation was 55 (19–84). The overall response rate was 47.9%, including 32.4% CR rate when a median of 3 cycles was applied. With a median follow-up of 5 months, the median OS was 5 months. Grade 3–4 neutropenia and thrombocytopenia were the most common hematological toxicities. The real-world data from our cohort showed the Pola-BR is an effective option with a manageable toxicity profile
