Adoption Model of Social Customer Relationship Management in the Palestinian Banking Sector

Social CRM is a new technology that integrates social networking activities within traditional CRM itself. Social media might be the most effective strategy in the context of CRM technology concerning the availability of efforts and time by owners. Therefore, it’s important for financial institutions to take advantage of it upon this opportunity by considering social CRM as part of development and enhancing relationship with their customers. Nevertheless, little empirical studies have focused on adoption of social CRM in banking sector. This research paper aims to investigate the factors that impact banks’ intention to adopt social CRM, based on combining the Technology-Organization-Environment (TOE) with Technology Acceptance Model (TAM) as the theoretical framework. TOE variables such as top management support and relative advantages found to have a direct impact on the two TAM mediating variables (perceived usefulness and perceived ease of use), and an indirect impact on social CRM adoption. Further, results suggested that consumer pressure and competitive pressure have a direct impact on social CRM adoption. The researcher tested the hypothesis using structural equation modeling (SEM). The findings from a survey of 220 employees in banks in Palestine showed that all eight hypotheses were supported as both consumer pressure and competitive pressure in the environmental context have a significant direct impact on social CRM adoption intention, followed by top management support in organizational and technological contexts; relative advantages have the most significant impact on perceived ease of use and perceived usefulness which in turn, have a direct and significant impact on social CRM adoption intention. The contribution of the study, limitations, future studies and conclusion are presented.
Pending Issues on Professionals’ Well-Being: The Living and Working Together in Organization Perspective

Evolving research has increasingly recognized the crucial role of workers’ well-being in contributing to organizational effectiveness and survival, also studying the different factors that can influence it. This paper explores how the construct of living and working together in organizations (LWTO) can face two current organizational challenges in terms of well-being: 1. keeping a balance between performance and organizational quality of life; 2. managing the relationship with others’ differences. Thus, LTWO is understood as the possibility (or absence) of a good exchange between workers (identity and otherness), related to a clear and shared work purpose within a specific organizational culture of difference that allows diversity of expression through generative conflict. We tested our model using the exploratory structural equation modeling methodology with EQS-6.3. Our results show how well-being is in fact influenced by LWTO and highlights in particular the central role played by work purpose.
Student satisfaction with use of an online peer feedback system

Abstract We contribute to the growing evidence of the positive effect of use of online peer feedback tools on students’ teamwork skills development. We do so by exploring individual and contextual factors underlying satisfaction with using a peer feedback system alongside team projects. Employing path analytical framework and bootstrap methods, we analysed data from an international sample of 100 project teams in management studies. Drawing on procedural justice theory, we theorised and found support that students’ uncertainty avoidance orientation and virtuality in collaboration were positively related to their satisfaction with use of a peer feedback system. Such satisfaction in turn allowed them to be more effective team members. Our findings provide evidence for higher education institutions and instructors considering the adoption of online peer feedback systems alongside teamwork in their curricula. Specifically, peer feedback appears to be effective in the development of teamwork skills and students appreciate the opportunity to provide feedback to their peers in a structured and dedicated environment. Our findings are timely and of important practical significance as educational institutions increasingly rely on the use of computer-mediated technology during the COVID-19 pandemic.
Ecological notes on the filter-feeding water scavenger beetle, Spercheus stangli Schwarz and Barber, 1917 (Coleoptera: Spercheidae), on the Iriomote Island, Japan

Abstract Spercheus stangli Schwarz and Barber, 1917 (Coleoptera: Spercheidae) is distributed in South Asia and Southeast Asia. Its Japanese population is known only in one pond on the Iriomote Island. To better understand the ecology of this family and develop conservation strategies for S. stangli, we conducted field surveys and rearing experiments. Our results suggest that S. stangli is bivoltine or multivoltine. We concluded that ponds with substrates, such as wood fragments floating on the water surface, are important habitats for the conservation of these beetles.
Performance Assessment of Optical Satellite-Based Operational Snow Cover Monitoring Algorithms in Forested Landscapes

Forest cover is a crucial factor that influences the performance of optical satellite-based snow cover monitoring algorithms. However, evaluation of such algorithms in forested landscapes is rare due to lack of reliable in situ data in such regions. In this investigation, we assessed the performance of the operational snow detection (SCA) and fractional snow cover estimation (FSC) algorithms employed by the Copernicus Land Monitoring Service for High-Resolution Snow & Ice Monitoring (HRSI) with a combination of Sentinel-2 and Landsat-7/8 satellite scenes, lidar-based, and in situ datasets. These algorithms were evaluated over test sites located in the forested mountainous landscape of the Pyrenees in Spain and the Sierra Nevada in the USA. Over the Pyrenees site, the effectiveness of snow cover detection was evaluated with respect to a time-series of in situ snow depth measurements logged over test plots with different aspects, canopy cover, and solar irradiance. Over the Sierra Nevada site, the impact of ground vegetation was assessed over the under canopy fractional snow cover retrievals using airborne lidar-derived fractional vegetation cover information. The analyses over the Pyrenees indicated a good accuracy of snow detection with the exception of plots with either dense canopy cover or insufficient solar exposure (shaded forested slope), or both. The operational HRSI algorithm yielded similar performances (25–30% RMSE) as the computationally intensive spectral unmixing approach while retrieving the subcanopy ground FSC over the Sierra Nevada site. It was observed that a more accurate lidar-derived tree cover density map did not improve the subcanopy FSC retrievals.
The Prevalence of Cyberbullying among Adolescents: A Case Study of Middle Schools in Vietnam

This paper aims to investigate the prevalence of cyberbullying among Vietnamese adolescents. Special emphasis was placed on gender differences regarding different forms of cyberbullying and victimization. In this study, 200 middle school students from four state schools in Vietnam were online surveyed to obtain information about the prevalence of cyberbullying and victimization. The results show that most of the students used the Internet daily and that almost all of them possess mobile telephones. On average, 7% of students reported that they have cyberbullied others online, whilst 14% of them were victims of cyberbullying. The most common types of victimization reported by students were harassment including “prank or silent phone calls” or “Insults on instant messaging and website”. There were not any significant gender differences in cyberbullying and being victimized by cyberbullies than females.
A GRASP-ALNS combination for robust pickup and delivery problem

One of the well-studied routing issues is the Pickup and Delivery Problem (PDP). It aims to route a fleet of vehicles based on a depot to satisfy a set of transport requests subject to numerous constraints. In real-life cases, the satisfaction of those requests over a given time slot (1 day for example) may become impossible while respecting all problem constraints. Therefore, the studied variant is characterised by the selective aspect which consists of choosing a subset of demands to be honoured. In addition, travel times between sites may be uncertain and may vary according to several scenarios. The robustness consists then at finding a solution which remains feasible over all scenarios. Therefore, the goal of this study is to introduce lexicographic and metaheuristic approaches to solve the Robust Selective PDP (RSPDP). Numerous tests have been done on new instances for the considered variant, in order to show the efficiency of proposed approaches.
LEXICAL COMPETENCE UNDERLYING SECOND LANGUAGE WORD ASSOCIATION TASKS

Abstract This study investigated the constructs underlying second language (L2) word association (WA) with regard to three dimensions of lexical competence—size, organization, and accessibility—and the lexical performance of speech. One-hundred and thirteen Japanese learners of English completed a computer-delivered oral WA task along with three vocabulary tasks: a form-recall gap-filling task (size), a primed lexical decision task (organization and accessibility), and an oral cartoon narrative (lexical richness). Regression analyses explored how well these lexical competence and performance scores predicted two WA outcome variables: response profiles and response times. Form-recall vocabulary knowledge, (collocational) priming, and lexical richness explained a large amount of variance in WA response type profiles (Nagelkerke’s pseudo R2 = .901). Form-recall vocabulary knowledge and lexical decision time explained 28.5% of the variance of WA response times. A three-stage model of L2 WA task performance is proposed to account for the constructs underlying WA performance.
Urethral configuration and mobility during urine leaking described using real-time transperineal ultrasonography

Purpose The aim of this study was to explore differences in the bladder neck configuration and segmental urethral mobility during the cough stress test (CST) in the supine and standing positions between women with and without stress urinary incontinence (SUI). Methods This prospective study included 100 control women and 100 incontinent women who had a CST with transperineal ultrasonography. The bladder neck configuration and urethral mobility were described in terms of urethral funneling, bladder neck descent (BND), retrovesical angle (RVA), urethral rotation angle, and urethral mobility at six points along the urethra (vectors 1 to 6). The two groups’ ultrasound findings in the two positions were compared. Results Valid data were collected from 78 control women and 90 women with SUI. Significant differences were found in age and body mass index between the two groups (P<0.01). Urethral funneling was found in 33 women (36.7%) with SUI and five continent women (6.4%) and altered little in the standing position. In the standing position, the mean RVA significantly increased (160° to 179°, P<0.001) in the SUI group; The mean vector of points 1 to 6 significantly increased in the control group (all P<0.001). The RVA, BND, and vectors 1 to 4 were significantly greater (all P≤0.01) in women with SUI than without, in both positions. Conclusion Urethral funneling was an intrinsic anatomical characteristic relative to SUI. Weak upper- and mid-urethral support and an unstable connection between the trigone and proximal urethra were the anatomical signs of SUI.
Stable oxygen and hydrogen isotope compositions of the Messoyakha and Pestsovoe pingos in northwest Siberia as markers of ice core formation

Pingos are indicators of modern and past conditions of permafrost. In total, 1,620 pingos have been identified on the Yamal and Gydan peninsulas in western Siberia. The main purpose of this study is to consider the distribution of stable isotopes in pingo ice cores formed under conditions of open and closed systems. Two pingos from ice cores of different origin in the continuous permafrost zone of northwest Siberia have been considered: the Messoyaha‐1 pingo (10.5 m in height) and the Pestsovoe pingo (17 m in height). Drilling of the ice core was performed with continuous sampling of an undisturbed frozen core. Ice formation was estimated according to the Rayleigh fractionation in a closed‐system versus an open‐system framework. For the Pestsovoe pingo, a pronounced decrease in δ18O values with corresponding increase in dexc with depth indicates a closed system upon freezing of the lake talik from the top down. For the Messoyakha‐1 pingo, the values of δ18O and δ2Н showed a weak tendency to decrease with depth, with values of dexc varying randomly. Ice that was segregated in the overlying and underlying sediments had similar values of δ18O and δ2Н and a low slope. Isotopically nonequilibrium ice formation was established for ice which had been segregated in a closed system and for ice cores formed in an open to semiclosed system. The vacuum mechanism of water suction from the surrounding lake or lake talik may have played a significant role during the formation of the upper ice core of the Messoyakha‐1 pingo and its additional growth.
The Enhanced Beneficial Effect of Extra Virgin Olive Oil Over Evening Primrose Oil on Oxidative Stress, and Liver Function in Male Arthritic Rats

Aims: Rheumatoid arthritis (RA) is characterized by the onset of oxidative stress. This study aimed to evaluate the enhancing of extra virgin olive (EVOO) and Evening primrose oil (EPO) on oxidative stress and liver enzymes in male Wistar rats and compare between them. Place and Duration: Faculty of Science biochemistry department, Between July 2018 and August 2018. Methodology: A Subcutaneous injection of 200 μl of Freund's complete adjuvant into a footpad of the right hind leg of Wistar male rats at two consecutive days induced RA. Rats received EVOO and EPO daily by oral gavage needle with gauge 18 at doses of 5 mg/kg b.wt. /day. for 10 and 21 days. No loss was recorded in the experimental rats. Results: A significant depletion in serum Reduced glutathione content (GSH), glutathione Original Research Article Kandeil et al.; JPRI, 33(32A): 14-26, 2021; Article no.JPRI. 69730 15 peroxidase (GPX), and glutathione s transferase activities (GST) in arthritic rats compared to normal rats after 10 and 21 days of induction which improved significantly after 10 and 21 days of EPO and EVOO treatments. EPO and EVOO treatments for 21 days increased the GSH and GPX compared to 10 days treatments while no difference in GST activity. EVOO treatment improved GSH and GPX after 10 and 21 days than EPO treatment. The elevated uric acid levels in arthritic rats were markedly ameliorated as a result of EVOO and EPO treatment administration. Increased lipid peroxidation products (MDA), rheumatoid factor, and liver enzyme (Alanine transaminase ALT and Aspartate transaminase AST) were recorded in arthritic rats and they significantly progressed after EPO and EVOO treatments for 10 and 21 days but EVOO had the best effect at 21 days. Conclusion: EVOO and EPO showed significant antioxidant efficacies and improved affected liver enzymes due to rheumatoid arthritis onset. When comparing olive oil has more antioxidant properties than evening primrose oil, so we recommend more studies on olive oil combination with anti-arthritic medications to improve their efficacies with less toxicity.
Participation in a randomised controlled trial (RCT) of metformin in gestational diabetes mellitus (GDM): pregnant women’s perceptions and experiences of the decision-making process

Background: Research in pregnancy and childbirth is required to advance healthcare needs for this population. Fears around potential fetal risk and the history of drug scandals renders it an area of research that is somewhat neglected. Due to the growing medical complexities facing pregnant women, efforts have been made in recent times to recognise the ethical importance of including this population in clinical research. Although clinical trials are becoming more common in pregnancy, recruitment of this population remains difficult with a common assumption that pregnant women would be reluctant to participate in clinical trials. This study set out to explore pregnant women’s perspectives and experiences of the decision-making process to participate in a randomised controlled trial of metformin in gestational diabetes mellitus (the EMERGE clinical trial). Methods: This study employed a qualitative descriptive design with thematic analysis. Data were collected by conducting individual semi-structured interviews (n=11) with participants (n=9) and decliners (n=2) of the EMERGE clinical trial. Results: The main findings reveal that a significant perception of personal benefit from participation was the biggest influence on women’s decisions to participate. Concerns about the impact of gestational diabetes on their pregnancies, the option of a favourable intervention treatment, a low perception of risk associated with the trial and the opportunity to help medical research appeared to have significantly influenced their decision. Receiving detailed information, personal interactions with the study team, a perception of voluntariness in participation and accessibility of the trial positively impacted on women’s decisions to participate. Conclusions: Personal contact during recruitment, presenting clear and thorough trial information, providing previous participant testimonials, and facilitating women to participate in clinical trials are all important strategies when trying to enhance recruitment in pregnancy trials. Further research on pregnant women declining participation in clinical trials is needed.
Dynamic Loads and Response of a Spar Buoy Wind Turbine with Pitch-Controlled Rotating Blades: An Experimental Study

New large-scale laboratory data are presented on a physical model of a spar buoy wind turbine with angular motion of control surfaces implemented (pitch control). The peculiarity of this type of rotating blade represents an essential aspect when studying floating offshore wind structures. Experiments were designed specifically to compare different operational environmental conditions in terms of wave steepness and wind speed. Results discussed here were derived from an analysis of only a part of the whole dataset. Consistent with recent small-scale experiments, data clearly show that the waves contributed to most of the model motions and mooring loads. A significant nonlinear behavior for sway, roll and yaw has been detected, whereas an increase in the wave period makes the wind speed less influential for surge, heave and pitch. In general, as the steepness increases, the oscillations decrease. However, higher wind speed does not mean greater platform motions. Data also indicate a significant role of the blade rotation in the turbine thrust, nacelle dynamic forces and power in six degrees of freedom. Certain pairs of wind speed-wave steepness are particularly unfavorable, since the first harmonic of the rotor (coupled to the first wave harmonic) causes the thrust force to be larger than that in more energetic sea states. The experiments suggest that the inclusion of pitch-controlled, variable-speed blades in physical (and numerical) tests on such types of structures is crucial, highlighting the importance of pitch motion as an important design factor.
Monolayer Molybdenum Disulfide Nanoribbons with High Optical Anisotropy

2D molybdenum disulfide (MoS2) has shown promising prospects for the next generation electronics and optoelectronics devices. The monolayer MoS2 can be patterned into quasi‐1D anisotropic MoS2 nanoribbons (MNRs), in which theoretical calculations have predicted novel properties. However, little work has been carried out in the experimental exploration of MNRs with a width of less than 20 nm where the geometrical confinement can lead to interesting phenomenons. Here, MNRs are prepared with width between 5 and 15 nm by direct helium ion beam milling. High optical anisotropy of these MNRs is revealed by the systematic study of optical contrast and Raman spectroscopy. The Raman modes in MNRs show strong polarization dependence. Besides that the E′ and A′1 peaks are broadened by the phonon‐confinement effect, the modes corresponding to singularities of vibrational density of states are activated by edges. The peculiar polarization behavior of Raman modes can be explained by the anisotropy of light absorption in MNRs, which is evidenced by the polarized optical contrast. The study opens the possibility to explore quasi‐1D materials with high optical anisotropy from isotropic 2D family of transition metal dichalcogenides.
How Do Subway Signs Affect Pedestrians’ Wayfinding Behavior through Visual Short-Term Memory?

Recently, subways have become an important part of public transportation and have developed rapidly in China. In the subway station setting, pedestrians mainly rely on visual short-term memory to obtain information on how to travel. This research aimed to explore the short-term memory capacities and the difference in short-term memory for different information for Chinese passengers regarding subway signs. Previous research has shown that people’s general short-term memory capacity is approximately four objects and that, the more complex the information, the lower people’s memory capacity. However, research on the short-term memory characteristics of pedestrians for subway signs is scarce. Hence, based on the STM theory and using 32 subway signs as stimuli, we recruited 120 subjects to conduct a cognitive test. The results showed that passengers had a different memory accuracy for different types of information in the signs. They were more accurate regarding line number and arrow, followed by location/text information, logos, and orientation. Meanwhile, information type, quantity, and complexity had significant effects on pedestrians’ short-term memory capacity. Finally, according to our results that outline the characteristics of short-term memory for subway signs, we put forward some suggestions for subway signs. The findings will be effective in helping designers and managers improve the quality of subway station services as well as promoting the development of pedestrian traffic in such a setting.
Steam Reforming of Ethylene Glycol over MgAl2O4 Supported Rh, Ni, and Co Catalysts

Steam reforming of ethylene glycol (EG) over MgAl2O4 supported metal (15 wt % Ni, 5 wt % Rh, and 15 wt % Co) catalysts was investigated using combined experimental and theoretical methods. Compared to highly active Rh and Ni catalysts with 100% conversion, the steam reforming activity of EG over the Co catalyst is comparatively lower with only 42% conversion under the same reaction conditions (500 °C, 1 atm, 119 000 h–1, S/C = 3.3 mol). However, CH4 selectivity over the Co catalyst is remarkably lower. For example, by varying the gas hour space velocity (GHSV) such that complete conversion is achieved for all the catalysts, CH4 selectivity for the Co catalyst is only 8%, which is much lower than the equilibrium CH4 selectivity of ∼24% obtained for both the Rh and Ni catalysts. Further studies show that varying H2O concentration over the Co catalyst has a negligible effect on activity, thus indicating zero-order dependence on H2O. These experimental results suggest that the supported Co catalyst is a promi.
