Optimizing the Deposition of Thin Layers of Organic-Inorganic Hybrid Perovskite Methylammonium Lead Iodide (CH3NH3PbI3) on Large Surfaces through Their Optical Properties

Nowadays, most of the Research and Development (R&D) efforts devoted to perovskite solar cells have been focused on achieving higher power conversion efficiencies, by using small sized substrates with even smaller active areas. The present paper proposes a method for optimizing the deposition of thin layers of organicinorganic hybrid perovskite methylammonium lead iodide (CH3NH3PbI3) on large surfaces (up to 75 mm x 75 mm) via spin coating procedures, performed in a clean room environment at room temperature and by considering their optical properties to assess their quality. Thus, in order to map the deposited area and realize studies about their optical properties, the absorption coefficient, the refractive index and layers thicknesses were determined by using a high accuracy spectroscopic ellipsometer system based on rotating compensator ellipsometer (RCE) technology from the J.A. Woolam Co. as functions of the wavelength, within a spectral range from 250 to 800 nm. Also, the samples were studied with a fluorescence spectroscopic system, in order to evaluate their photoluminescence properties and, in order to validate the chosen methodology; an Atomic Force Microscopy was used to verify the layers uniformity and thicknesses.
Banking

In his opening remarks, Mr. Lowrie said that bankers are considered by some to be staid and conventional, whereas in terms of computer usage the bankers have been far from conventional. From a position in 1960 of perhaps the least significant user of all the Sectors represented at the Conference, banking has become the largest. Excepting the Government Sector, almost 20% of all systems and programming talent works within the Finance Sector.
Two Faces of Water in the Formation and Stabilization of Multicomponent Crystals of Zwitterionic Drug-Like Compounds

Two new hydrated multicomponent crystals of zwitterionic 2-aminonicotinic acid with maleic and fumaric acids have been obtained and thoroughly characterized by a variety of experimental (X-ray analysis and terahertz Raman spectroscopy) and theoretical periodic density functional theory calculations, followed by Bader analysis of the crystalline electron density) techniques. It has been found that the Raman-active band in the region of 300 cm−1 is due to the vibrations of the intramolecular O-H.O bond in the maleate anion. The energy/enthalpy of the intermolecular hydrogen bonds was estimated by several empirical approaches. An analysis of the interaction networks reflects the structure-directing role of the water molecule in the examined multicomponent crystals. A general scheme has been proposed to explain the proton transfer between the components during the formation of multicomponent crystals in water. Water molecules were found to play the key role in this process, forming a “water wire” between the COOH group of the dicarboxylic acid and the COO– group of the zwitterion and the rendering crystal lattice of the considered multicomponent crystals.
What Do I Do in a World of Artificial Intelligence? Investigating the Impact of Substitutive Decision-Making AI Systems on Employees' Professional Role Identity

Artificial intelligence (AI) systems in the workplace increasingly substitute for employees’ tasks, responsibilities, and decision-making. Consequently, employees must relinquish core activities of their work processes without the ability to interact with the AI system (e.g., to influence decision-making processes or adapt or overrule decision-making outcomes). To deepen our understanding of how substitutive decision-making AI systems affect employees’ professional role identity and how employees adapt their identity in response to the system, we conducted an in-depth case study of a company in the area of loan consulting. We qualitatively analyzed more than 60 interviews with employees and managers. Our research contributes to the literature on IS and identity by disclosing mechanisms through which employees strengthen and protect their professional role identity despite being unable to directly interact with the AI system. Further, we highlight the boundary conditions for introducing an AI system and contribute to the body of empirical research on the potential downsides of AI.
Existence and Approximation of Fixed Points of Enriched Contractions and Enriched φ-Contractions

We obtain existence and uniqueness fixed point theorems as well as approximation results for some classes of mappings defined by symmetric contractive type conditions in a convex metric space in the sense of Takahashi. By using a new approach, i.e., the technique of enrichment of contractive type mappings, we obtain general results which extend the well known Banach contraction mapping principle from metric spaces as well as other corresponding results for enriched mappings defined on Banach spaces. To indicate the relevance of our new results, we present some important particular cases and future directions of research.
Warm-Glow Giving, Hedonism, and Their Influence on Muslim User Engagement on Loan-Based Crowdfunding Platforms

This paper investigates how platform design features affect the funding motivation of Muslim users on loan-based crowdfunding platforms. Theoretically grounded in Andreoni’s warm-glow giving theory and Sober and Wilson’s model of evolutionary and psychological giving, this work has high practical relevance, given the increasing demand for Islamic financial products. Loan-based crowdfunding platforms are important to the unique context of this research since Islamic religious constraints regulate monetary transactions involving lending. We used a scenario-based survey developed on the basis of a pilot study and confirmed by our manipulation check. The results show that “hedonism” represented by monetary interest negatively affected Muslim users’ willingness to engage in a loan-based crowdfunding project. This finding challenges the commonly agreed-upon egoistic motivator for loan-based crowdfunding platforms (i.e., monetary interest), which is based on Western Christian and Chinese Confucian capitalist economic and financial paradigms. Remarkably, we also found that Muslim funders’ level of willingness to engage on the hedonistic platform had an exponentially positive effect on the amount of money that funders were willing to lend. By contrast, “warm-glow giving,” manifested as belonging to a community, had no effect on users’ engagement. Implications of these findings for theory and practice are discussed.
Imaging the effect of aeration on particle fouling mitigation in a submerged membrane filtration using a photointerrupt sensor array

ABSTRACT A non-destructive in-situ optical method using a photointerrupt sensor array was adopted to determine the variation of cake layer thickness in a membrane filtration process with aeration. The effect of air sparging on fouling mitigation was evaluated at different aeration conditions. Results from three-dimensional fouling contour studies showed that the average cake layer thickness increased proportionally with time during the initial period due to quick deposition of particles on the membrane surface and then growth rate of cake layer slowed down. The semi-continuous aeration could also suppress the membrane fouling at the same level as observed at continuous aeration.
Evaluating the effectiveness of live animal shows at delivering information to zoo audiences

ABSTRACT Live animal shows, which combine animal facts with trained behaviours, are commonly used to engage zoo visitors globally. However, such shows have been criticised for portraying a potentially unhelpful image of ‘performing animals’ and have raised issues of animal welfare ethics. Little is known about the educational effectiveness of these shows. Furthermore, the impact of ‘tricks’, used as attention-grabbing hooks, has received limited research attention. We evaluated the impact of a sea lion and a mixed species bird show on audience knowledge of animal facts. Over a quarter of zoo visitors attended some form of live animal show, demonstrating quantitatively that they are a major potential source of knowledge transfer. Show audiences were questioned immediately before (n = 299) or after (n = 265) each performance about relevant show content knowledge. Additionally, a general zoo visitor survey (n = 160) investigated post-visit knowledge recall. Audiences demonstrated significantly higher animal knowledge post-show compared to pre-show. Conservation action awareness showed weak positive change post-show. Audience education levels and weather conditions also had a weak positive effect on correct responses. However, animals performing trick-type behaviours were found to cause confusion regarding natural adaptations. We conclude that live animal shows should prioritise natural behaviours with a focus on conservation action.
Teaching drama differently in Sri Lankan secondary schools

ABSTRACT Arts subjects such as drama provide an effective context for developing 21st century skills, yet drama teaching in Sri Lanka is still mainly delivery through traditional, lecture-based methods. This article presents evaluation results of a drama-based intervention program that was designed specifically to develop junior secondary school students’ creative thinking capacity and adaptability skills in the Sri Lankan context. The participants were 128 students aged 11-12 years in Year 7 drama classes. The program was implemented over twelve consecutive weeks in weekly two-hour sessions by regular drama teachers who had been trained in a process drama teaching approach. Results evidenced a positive effect emerging from the intervention: creativity and adaptability test scores of the students in the intervention group increased significantly compared to those of the students in the control and active control groups. This paper identifies implications of these findings for Sri Lankan drama teaching and learning and beyond.
Consumer behavior and environmental sustainability in tourism and hospitality: a review of theories, concepts, and latest research

Abstract Diverse forms of environmental problems pose a serious threat to the natural environment. Environmental sustainability is the foremost topic in the contemporary tourism and hospitality industry. Environmentally-sustainable consumer behavior is an important aspect of environmental protection, which eventually benefits the society. In order to better understand environmentally-sustainable consumption and promote environmentally responsible consumer behavior, this research provides a sound conceptualization of environmentally-sustainable consumer behavior, and presents a systematic review and perspective on theories (theory of reasoned action, norm activation theory, theory of planned behavior, model of goal-directed behavior, and value-belief-norm theory) established in tourism and environmental psychology. In addition, this study introduces the essential drivers of environmentally-sustainable consumer behavior (green image, pro-environmental behavior in everyday life, environmental knowledge, green product attachment, descriptive social norm, anticipated pride and guilt, environmental corporate social responsibility, perceived effectiveness, connectedness to nature, and green value). Lastly, this paper provides the values of the latest studies on the special issue of environmental sustainability and consumer behavior in tourism and hospitality. This study as an introductory paper along with other articles in this special section help enable a collaboration platform across tourism and hospitality fields in pursuit of universal goals for promoting pro-environmental consumption and environmental sustainability.

One-Pot Assembly of Microfibrillated Cellulose Reinforced PVA–Borax Hydrogels with Self-Healing and pH-Responsive Properties

A facile, environmentally benign approach has been developed for the preparation of dynamic, multiresponsive, and self-healing hydrogels from inexpensive bamboo pulp, poly(vinyl alcohol) (PVA), and borax. The microfibrillated cellulose (MFC) reinforced PVA–borax hydrogels were produced through a one-pot route in conjunction with ball milling and physical blending in tandem in aqueous medium. In this way, MFC particles could be efficiently generated and well-dispersed in a polymer matrix, and they have been verified by scanning electron microscopy. The rheology analysis indicated a close relationship between the mechanical strength and the MFC loading and ball milling time. Due to the dynamic equilibrium of the didiol–borax linkages and the reinforcement of MFC fibers, the hydrogels showed enhanced self-healing behavior and mechanical stiffness, which was also supported by rheology analyses. In addition, the hydrogels were found to be sensitive to the pH value. The hydrogels present a solvent or gel state .
Comparison of analgesic requirements in robot-assisted versus conventional laparoscopic abdominal surgeries

Background and Aims: Robot-assisted surgery is advantageous in the precision of tissue handling and shorter postoperative recovery. We compared postoperative analgesic requirements in laparoscopic versus robot-assisted surgery in the first 24 h as our primary objective. The secondary outcomes were extubation on table, time to ambulation, and length of ICU stay. Material and Methods: After approval from the ethics committee 48 patients undergoing either laparoscopic (group L [n = 24]) or robotic abdominal surgery (group R [n = 24]) were evaluated for analgesic requirements postoperative targeting a numerical rating scale ≤3 in a prospective comparative study. Postoperative patients were allotted to a three-tier pain management, level 1 comprising paracetamol 1 g intravenously every 8 h, level 2, 1.5 mg/kg tramadol every 8 h, and level 3 fentanyl 0.5 μg/kg. The total analgesic consumption in the first 24 h was calculated for each group. Statistical analysis was performed using the Chi-square test and Mann-Whitney U test. Results: Age, weight, and types of surgery were comparable between the groups. The intraoperative opioid use was comparable between both groups but the duration of surgery was longer in group R. Postoperative analgesic requirements were significantly less in group R (P = 0.024) and the length of ICU stay was shorter (P < 0.05). The time to ambulation was significantly shorter in group R patients (P < 0.001). Conclusion: Analgesic requirements were significantly less in robot-assisted laparoscopic surgery in the first 24 h. The time to ambulation and length of ICU stay were shorter in the robot-assisted group in comparison to the laparoscopic group.
Effect of transcutaneous electrical nerve stimulation on quality of recovery and pain after abdominal hysterectomy

Background and Aims: Transcutaneous electrical nerve stimulation (TENS) is a noninvasive complementary therapy for postoperative pain management. The effect of TENS on quality of recovery (QoR) and pain treatment in the early postoperative period is not well documented. The aim of this study was to evaluate the effect of TENS on postoperative QoR and pain in patients who had undergone a total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAH + BSO). Material and Methods: Fifty-two patients were randomized into two groups: control (sham TENS treatment) and TENS (TENS treatment). QoR, dynamic pain, and static pain were evaluated after surgery. Results: The QoR score was significantly higher in the TENS group as compared with that in the control group (P = 0.029). Pain scores during coughing (dynamic pain) were significantly less in TENS group compared to control group (P <0.001). However, there was no between-group difference in pain scores at rest (static pain) or total analgesic consumption (P = 0.63 or P = 0.83, respectively). Conclusion: TENS may be a valuable tool to improve patients' QoR and dynamic pain scores after TAH + BSO.
Effect of intracuff dexamethasone on incidence and severity of post operative sore -Prospective randomized study

Background and Aims: Postoperative sore throat (POST) continues to be a common concern following endotracheal intubation. Objectives of the present study were to compare the effects of intracuff dexamethasone on the incidence and severity of POST, postoperative hoarseness of voice (POHV) and cough (POC). Material and Methods: This prospective, randomized, double blinded study was conducted in 60 patients undergoing short laparoscopic surgery lasting <2 h. Patients were randomly allocated into Group A and B. After intubation, endotracheal tube (ETT) cuffs were filled with saline in group A and with 0.1 mg/kg dexamethasone in group B. All patients received general anesthesia as per a standardized protocol. Incidence and severity of POST, POC, and POHV were assessed. Results: As compared to group A, the number of patients who had sore throat was significantly low in group B at 2, 6, 12, and 24 h (P < 0.001). Though more number of patients in group A had postop cough at all time points and postop hoarseness of voice at 2,6, and 12 h, the difference was statistically significant only at 2 h and 6 h for both. Severity as well as the incidence of POST, POC, and POHV showed a downward trend in both groups with time. In group B, no patient had POST after 12 h, POC after 6 h, and none complained of POHV in the postoperative period. Conclusion: Intracuff dexamethasone 0.1 mg/kg significantly reduces incidence and severity of POST, POC, and POHV which occur following general anesthesia with endotracheal intubation in patients undergoing short pelvic laparoscopic procedures lasting <2 h.
Study of the Impact of Sweet Potato (Ipomea batatas) Meal as a Source of Energy in the Diets of Broilers at Starter and Finisher Stages of Growth in Zamfara State, Nigeria

The experiment was conducted to determine the impact of feeding sweet potato meal to broilers. A total of two hundred and fifty (250) day old broilers of Abore acres strain were used for the trial. The birds were randomly divided in to 25 groups of 10 chicks each. Five groups were randomly allocated to five dietary treatments as replicates. The treatments consisted of diet 1 (100% maize/ 0% sweet potato), diet 2 (75% maize/ 25% sweet potato), diet 3 (50% maize/ 50% sweet potato), diet 4 (25% maize/ 75% sweet potato) and diet 5 (0% maize/ 100% sweet potato). Data on feed intake, water intake, mortality, feed conversion ratio and body weight gain were recorded. The proximate analysis of the feed samples and sweet potato meal were carried out. The data collected Original Research Article Anka et al.; SARJNP, 4(1): 24-33, 2021; Article no.SARJNP. 65026 25 at both starter and finisher were subjected to Analysis of Variance (ANOVA) using SAS statistical package. The results recorded at both starter and finisher stages indicated that, there was significant difference (P<0.05) on body weight gain and feed conversion ratio while there was no significant difference (P>0.05) on feed intake, water intake and mortality. It could be concluded from the results of the study that, control diet and 50% level of inclusion are better for broiler starters and finishers respectively.
The Emerging Field of Nutritional Mental Health: Inflammation, the Microbiome, Oxidative Stress, and Mitochondrial Function

We live in a transformational moment for understanding the etiology of mental disorders. The previous leap in understanding occurred 60 years ago, which led us to incorporate psychopharmacology into our curricula to address the chemical basis of neurotransmitter function, especially as explained through the then-popular catecholamine hypothesis. The current revolution is broader, consisting of the rapidly accumulating knowledge of how inflammation, microbiome imbalance (gut dysbiosis), oxidative stress, and impaired mitochondrial output affect brain function. Suitable interventions for fighting inflammation, restoring normal gut function, reducing oxidative stress, and improving mitochondrial metabolism incorporate lifestyle variables, including nutrients and probiotics. This article invites readers to stay abreast of this emerging model of the biological basis of mental illness, given that it has particular relevance for those readers interested in alleviating the suffering of individuals with mental disorders. This overview describes the basis for a new field in mental health: nutritional psychiatry/psychology.
A Contrastive Analysis between English and Indonesian Noun Phrases in The Utterances of The Character “Killmonger” in The Movie “Black Panther 2018”

The movie “Black Panther (2018)” was directed by Ryan Coogler and starred Chadwick Boseman (T’Challa), and Michael B Jordan (Erik Killmonger). It is a movie based on the Marvel Comics and set in the fictional African nation of Wakanda. Using descriptive qualitative method, this study entitled “A Contrastive Analysis Between English and Indonesian Noun Phrases in The Utterances of The Character ‘Killmonger’ in the ‘Black Panther 2018’”, was done to find out similarities and differences between English and Indonesian Noun Phrases through a contrastive analysis according to Jumanto (2017), in which selection and description are made in table form and below the table, the comparison, prediction and verification of lay translators learning problems are made. Furthermore, the noun phrases were categorized by the arrangement of modifiers as Standard Noun Phrases. This is a construction where the arrangement of modifiers is found around the noun headword. Constructions include, Head + Modifier, Modifier + Head, and Modifier + Head + Modifier. After a contrastive analysis, we have found out now that noun phrases in English and Indonesian are similar constructions except for a few cases. In this research, 100 data of noun phrases were discovered from the utterances of “Killmonger. ” Most English noun phrases are structured M+H where the modifiers are usually before the noun headword. Its Indonesian counterparts are of opposite constructions H+M. This shows that modifiers in the Indonesian noun phrase are mostly found after the noun headword. While most of the modifiers in both languages are similar, in the Indonesian language, there is a unique modifier in form of a suffix. Nevertheless, when translated, both noun phrases have similar meaning but slightly different constructions i.e. Your ancestors (M+H) – Leluhurmu (H+M), Panther claws in his chest (M+H+M) – Cakar panther di dadanya (H+M).
