Effects of Motivational and Behavioral Factors on Job Productivity: An Empirical Investigation from Academic Librarians in Pakistan

The major objective of the current study was to find out the impact of motivational factors on the job outcomes of librarians working in HEC-recognized university libraries in Pakistan. A survey research method followed by predictive correlational design was applied to test the constructed hypotheses in this study. The population of the study was library professionals working in the university libraries of Lahore, Pakistan. There were 13 public sector universities and 21 private sector universities. The census sampling technique was used to collect data from the respondents of the 34 universities. Data were collected with the help of a questionnaire. Out of 225 respondents, 189 completed questionnaires were received. Hence, the response rate was 84%. The gathered data were analyzed through SPSS software. Descriptive and inferential statistical tests were applied to find out the impact of motivational and behavioral factors on the job outcomes of information professionals. The findings of the study showed that different types of motivation influenced information professionals to carry out innovative and value-added services in the workplace. Rewards, a sense of honor, an amicable work environment, and autonomy were the key categories of motivation that encouraged information professionals to undertake efficient job performance. Recommendations provided through a framework based on the findings of the study will prove to be a benchmark for policymakers, human resource managers, and heads of institutions in order to formulate such techniques that might motivate information professionals for the implementation of user-centric services.
Log Betti cohomology, log étale cohomology, and log de Rham cohomology of log schemes over C

where Ωχ/c is the de Rham complex of X ([Gr2]). In this paper, we prove generalizations of these results to schemes over C endowed with logarithmic structures in the sense of Fontaine-Illusie. Let X be an fs log scheme ([Nl] (1.7)) over C whose underlying scheme X is locally of finite type over C. Then the analytic space X^ associated to X is endowed with the inverse image of the log structure of X. For an analytic space Y over C endowed with an fs log structure (like Xan), we will define a topological space F l o g which is endowed with a continuous surjective map τ : 7 l o g —> Y ((1.2)). We denote (Xan) log by Z £ g . We prove:
The variability of strength production capacities during a judo contest

Background. The muscular response of athletes in a judo contest is one of the most important aspect to measure with precision. Objective. Our purpose was to obtain and analyse the variability of strength associated to muscular performance parameters during a judo contest. Methods. Thirty-five men performed five 5-minute bouts with 15 minutes of passive rest. Immediately after each bout, muscular performance parameters were tested: countermovement jump (CMJ), maximal dynamic strength capacities (mean power velocity (MPV), mean strength (MS), maximum strength (MXS), mean power (MP) and maximum power (MXP)) in upper body, dominant (DHS) and non-dominant handgrip isometric strength (NDHS). ANOVA to compare baseline test data and successive bouts was used. Results. ANOVA revealed significant differences in NDHS (p<0.001), DHS (p<0.001), CMJ (p<0.001), MPV (p<0.001), MXS (p<0.001), MP (p<0.001) and MXP (p<0.001). No significant differences in MS (p = 0.008) were found. Some significant correlations between NDHS and ΔPMX (r=0.368, p=0.050), MPV and ΔMXS (r=0.528, p=0.001) and ΔMXP (r=0.683, p<0.001), MPX and ΔMXS (r=0.528, p=0.001) and ΔMP (r=0.877, p<0.001) were found. Conclusion. Due to judo contest can be considered a high intensity exercise, it produces an amount of muscular fatigue and therefore significant loss strength that it cannot be recovery during rest-times between successive bouts. For this reason, it was a high variability in strength production capacities, which are modified during a judo contest.
Two‐degree‐of‐freedom dynamic matrix control for distillation columns

Abstract Generally, most long‐range predictive control (LRPC) gives good set point responses in multivariable process control. However, on several occasions, little improvement in load rejection was observed when comparing LRPC with well‐tuned multiloop SISO controllers. In this study, the dynamic matrix control (DMC) algorithm is modified to improve disturbance rejection capability. A two‐degree‐of‐freedom DMC is proposed by incorporating the step‐response models for the major load disturbance. A load tuning factor is used to adjust the degree of load prediction. A non‐linear distillation column is used to test the effectiveness of the proposed algorithm. Simulation results show that, while maintaining good set point responses, the proposed algorithm outperforms the standard DMC algorithm for both the modeled and unmodeled load disturbances.
Random Number Generation With a Hybrid Conjugated Polymer Memristor

A two-terminal memristor was constructed from electrochemically doped poly(4-(6-(9H-carbazol-9-yl)hexyl)-4H-dithieno[3,2-b:2’,3’-d]pyrrole) (pC6DTP) and employed as a random number generator (RNG). The polymer exhibited a conductive nature that was dependent on its voltage history that was theorized to be due to two synergistic percolation mechanisms: one associated with the pendant electroactive heterocyclic rings and one associated with the polymer backbone conjugation. The generated random number (RN) stream was evaluated for “randomness” with select tests from NIST SP 800–22 Rev. 1a testing protocol, which indicated that the bitstream was classified as random as generated without any postprocessing, while the energy required to generate a bit was ca. 0.67 pJ.
New strong evidence for the importance of convective overshooting in intermediate-mass stars

Major differences between current series of stellar evolution calculations concern their opacities and treatment of convection. Accurate mass, radius, luminosity, and abundance data from eclipsing binaries now allow significant conclusions on these differences: binary stars with small convective cores are very well fitted by standard models using Los Alamos (but not Cox-Stewart) opacities. However, at just slightly larger masses, the moderately evolved binaries clearly require convective overshooting for a satisfactory fit. Precise radial velocities for F-type turnoff stars in IC 4651 and NGC 3680 not only confirm the signatures of overshooting observed in these clusters but also show that any such firm conclusions require proper identification of binaries and nonmembers. It is concluded that standard (and some overshooting) models are inconsistent with current precise data for intermediate-mass stars. Among the consequences of rejecting the older models, it is pointed out that ages for stars younger than roughly 4 Gyr will increase by up to 50-100 percent. 27 refs.
Deep radio synthesis images of globular clusters

Results are reported from a program of high-resolution and high-sensitivity imaging of globular clusters at 20 cm. The findings indicate that there is not a large number of pulsars in compact binaries which have escaped detection in single-dish pulse searches. Such binaries have been postulated to result from tidal captures of single main-sequence stars. It is suggested that most tidal captures involving neutron stars ultimately result in the formation of a spun-up single pulsar and the complete disruption of the main-sequence star. 27 refs.
Comparison of Dynamic Hip Screw and Proximal Femoral Nailing Techniques in Stable Intertrochanteric Fractures

Introduction Dynamic Hip Screw (DHS) and Proximal Femoral Nail (PFN) are two well-accepted modes of surgical treatments for intertrochanteric (IT) hip fractures. While studies have extensively explored the efficacy of one over the other in unstable fractures, the comparison is sparsely available for stable fractures. The main aim of this study is to compare DHS or PFN corrective surgeries in cases of stable IT fractures operated at the Hamad General Hospital, Doha, Qatar, between 2016 and 2018. Methods We conducted a retrospective data review of all stable IT fractures operated at the Hamad General Hospital, Doha, Qatar, between 2016 and 2018. Data were extracted from electronic medical CERNER records, including demographics, clinical notes, operative reports, radiographs, and imaging reports. Data review was followed by prospective data collection via phone about the current post-operative functional status of all cases. Data analysis was done on SPSS v.23. Study was approved by Medical Research Center (MRC) and Institutional Review Board (IRB) at Hamad Medical Corporation (HMC). Study Protocol ID: MRC-01-19-108 Results Out of 62 stable IT fractures operated at our center during the study period, 42 underwent DHS correction, while 20 had PFN. The mean age of the studied cohort was 66.56 years (± 15.95). Males were twice more than females. The mean duration of surgery was 83.73 minutes for DHS and 120.25 minutes for PFN. This difference was statistically significant (p < 0.001). Differences in intraoperative blood loss, duration between fracture and surgery, and length of hospital stay were all statistically insignificant. Patients who underwent PFN showed a higher frequency of return to ambulation (assisted and unassisted), while the number of patients with DHS was less for the functional outcome. Similarly, more post-PFN radiographs displayed union than post-DHS radiographs (55% and 38%, respectively). This difference was statistically insignificant. Conclusion Our study showed promising results for stable IT fractures treated with PFN. However, more data and prospective observational studies are required to establish more statistically significant results.
Strategizing risk information sharing framework among supply chain partners for financial performance

ABSTRACT Organisations are often reluctant and sometimes postpone sharing risk-related information with their partners. This paper aims to develop and analyse the risk-sharing model to explain the factors contributing to the timely and accurate sharing of risk-related information within the supply chain network. The data are collected from 199 supply chain experts working in different manufacturing companies through a structured questionnaire and then analysed using structural equation modelling. The result of this study reflects that strategic supply chain relationship (SCR) has a significant impact on risk information sharing (RIS) and external information integration (EII) while having an insignificant impact on internal information integration (III). On the other hand, supply chain technology internalisation (SCT) significantly impacts EII, III and risk-sharing mechanism (RSM). This study is one of the few empirical studies conducted to understand the antecedents of risk-sharing mechanisms in any supply chain network to enhance visibility and increase financial performance using the relational and integrational approaches.
Free transverse vibration of the fluid-conveying single-walled carbon nanotube using nonlocal elastic theory

The effects of flow velocity on the vibration frequency and mode shape of the fluid-conveying single-walled carbon nanotube are analyzed using nonlocal elastic theory. Results show that the frequency and mode shape are significantly influenced by the nonlocal parameter e0a/L. Increasing the nonlocal parameter decreases the real component of frequency and the decrease is more obvious for a lower flow velocity and a higher-order mode. In addition, a higher mode shape is observed with increasing the value of e0a/L. When a critical flow velocity is reached, the combination of first and second modes takes place. The mode shape for the combination is large relative to mode 3 due to the coupled frequency effect, especially including negative imaginary frequency. Furthermore, the mode shape of the combination increases as the nonlocal effect increases.
Bell Beaker Burial Customs in North-western France

Ever since large amounts of Bell Beaker complex pottery were first discovered within megalithic graves in north-western France, the Bell Beaker has been tightly tied to the ‘megalithic phenomenon’. However, the fact of construction of these various kinds of megalithic monument during the Middle to Late Neolithic pre-dates the users of Bell Beakers. While this is a case of the re-use of older funerary monuments, it is assumed that Bell Beaker funerary practices witness a shift from Neolithic collective burial to individual inhumation. For a long time finds from the megalithic graves have constituted our main source of information on the Bell Beaker complex in north-western France. However, these ‘artificial caves’ have biased our understanding of the Bell Beaker complex and, in particular, of its funerary practices. The re-assessment of old finds and recent large-scale excavations have brought to light a large number of new sites, revealing a greater diversity in Bell Beaker funerary practices in the region than had been perceived previously. In the first part, we set the broader picture, stating what we know or can say about funerary practices during the Recent and Late Neolithic (3350–2550 bc), before the beginning of the Bell Beaker phenomenon. We then discuss the different Bell Beaker burial practices (2550–1950 bc), their chronological and regional variabilities, and, above all, the research biases that might have affected their understanding.
Evolution of care in cirrhosis: Preventing hepatic decompensation through pharmacotherapy

Cirrhosis is a leading cause of morbidity and mortality, impacting more than 120 million people worldwide. Although geographic differences exist, etiologic factors such as alcohol use disorder, chronic viral hepatitis infections, and non-alcoholic fatty liver disease are prevalent in nearly every region. Historically, significant effort has been devoted to modifying these risks to prevent disease progression. Nevertheless, more than 11% of patients with compensated cirrhosis experience hepatic decompensation each year. This transition signifies the most important prognostic factor in the natural history of the disease, corresponding to a decline in median survival to below 2 years. Over the past decade, the need for pharmacotherapies aimed at reducing the risk for hepatic decompensation has been emphasized, and non-selective beta-blockers have emerged as the most effective option to date. However, a critical therapeutic gap still exists, and additional therapies have been proposed, including statins, rifaximin, and sodium-glucose cotransporter-2 inhibitors. Based on the results of innovative retrospective analyses and small-scale prospective trials, these pharmacotherapies represent promising options, but further studies, including randomized controlled trials, are necessary before they can be incorporated into clinical use. This report highlights the potential impact of these agents and others in preventing hepatic decompensation and discusses how this paradigm shift may pave the way for guideline-directed medical therapy in cirrhosis.
A Single Atomic Particle Forever Floating at Rest in Free Space: New Value for Electron Radius

An updated survey of mostly experimental spectroscopy work in Seattle on an individual closely-confined isolated atomic or elementary particle is presented. The classical notion of an atomic particle at rest in free space is discussed, and shown to be approximable by zero-point confinement of the particle in a laboratory trap. An important tool for cooling the particle, and in the case of an electron, for obtaining directly the difference of spin and cyclotron frequencies vs, vc, is side band excitation. The quantum numbers of the geonium "atom", an electron in a Penning trap, have been continuously monitored in a non-destructive way by the new "continuous" Stern-Gerlach effect. In this way the g-factors of electron and positron have been determined to unprecedented precision, ½g ≡ vs/vc ≡ 1.001 159 652 188(4), providing the most severe tests of QED and of the CPT symmetry theorem, for charged elementary particles. From the close agreement of experimental and theoretical g-values a new, 104 × smaller, value for the electron radius, Rg < 10-20 cm, may be extracted. Other important results are: confinement of the individual positron, Priscilla, for 3 months, a tenfold suppression of the natural width of the cyclotron resonance, detection of an isomeric (cyclotron-excited) state via mass-spectroscopy, isolation and continuous detection of an individual proton, confinement of ≈ 100 antiprotons slowed to ≈ 3000 eV, confinement of a Ba+ ion to 13 ≈ 100 nm, and the demonstration of quantum jumps in geonium and in an isolated, individual regular atomic particle, Ba+. Some new experiments are proposed.
Risks of Cardiac Arrhythmia Associated with COVID-19 Vaccination: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis aimed to summarize the current evidence regarding the association between coronavirus disease 2019 (COVID-19) vaccination and the risk of cardiac arrhythmia. MEDLINE, via PubMed and OVID, Scopus, CENTRAL, and Web of Science were searched using the relevant keywords to identify the relevant citations. Comprehensive Meta-analysis and Review Manager 5.4. 1 were used for all the statistical analyses. Seventeen studies (n = 567,033,087 patients) were included. The pooled analysis showed that the incidence of cardiac arrhythmia post-COVID-19 vaccination with Pfizer, Moderna, AstraZeneca, CoronaVac, and Sinopharm was 0.22%, 95% CI: (0.07% to 0.66%), 0.76%, 95% CI: (0.04% to 12.08%), 0.04%, 95% CI: (0.00% to 0.98%), 0.01%, 95% CI: (0.00% to 0.03%), and 0.03%, 95% CI: (0.00% to 18.48%), respectively. Compared to CoronaVac, Pfizer, Moderna, AstraZeneca, and Sinopharm had a higher incidence ratio rate (IRR; 22-times, 76-times, 4-times, and 3-times higher), respectively. Likewise, Pfizer, Moderna, and AstraZeneca showed a higher IRR than Sinopharm (7.3-times, 25.3-times, and 1.3-times higher). The current evidence shows that the incidence rate (IR) of cardiac arrhythmia post-COVID-19 vaccination is rare and ranges between 1 and 76 per 10,000. mRNA vaccines were associated with a higher IR of arrhythmia compared to vector-based vaccines. Inactivated vaccines showed the lowest IR of arrhythmia.
A Nonlinear Multimode Controller for Seamless off-Grid of Energy Storage Inverter Under Unintentional Islanding

A nonlinear multimode controller is proposed to achieve the whole process seamless off-grid of energy storage inverter (ESI) from the grid-connected state of current control mode to the islanded state of voltage control mode under unintentional islanding. Based on the presented design idea of intelligent equivalent substitution, NMC is composed of multimode voltage controller (MVC), multimode power compensator (MPC), and multimode current controller (MCC). MVC can control load voltage in islanding and maintain manipulated variables of load current in other modes. MPC can compensate the power flowing into grid and help inner loop reference value achieve the smooth drop, and also compensate for load current variation during grid connection. MCC can track the given current during grid-connection and make MPC quickly obtain the compensation of load power variation. The reference values of inner loop are logically split into the output of MVC, MPC, and MCC, so that the manipulated variables can be combined nonlinearly to achieve seamless off-grid of ESI under unintentional islanding. This article also analyzes the ESI stability with NMC during the off-grid process, and analyzes the relationship between manipulated variables by simulations. Finally, the correctness and effectiveness of proposed NMC are verified by experiments.
High power electrochemical capacitors based on carbon nanotube electrodes

Carbon nanotube sheet electrodes have been prepared from catalytically grown carbon nanotubes of high purity and narrow diameter distribution, centered around 80 A. Our study shows that the electrodes are free-standing mats of entangled nanotubes with an open porous structure almost impossible to obtain with activated carbon or carbon fiber. These properties are highly desirable for high power and long cycle life electrochemical capacitors. Specific capacitances of 102 and 49 F/g were measured at 1 and 100 Hz, respectively, on a single cell device with 38 wt % H2SO4 as the electrolyte. The same cell had a power density of >8000 W/kg.
Canada Lynx (Lynx canadensis) as Potential Reservoirs and Sentinels of Toxoplasma gondii in Northern Canada

Toxoplasma gondii is a zoonotic parasite globally infecting a wide range of species, including humans. Felids are the only known hosts that can excrete environmentally resistant oocysts into ecosystems. In boreal regions, Canada lynx (Lynx canadensis) are sought by hunters primarily for their fur, and they are occasionally eaten. We examined carcasses salvaged from trappers from boreal regions of eastern (n = 97) and western (n = 357) Canada. We detected T. gondii antibodies in fluid from thawed heart tissue using an enzyme-linked immunosorbent assay, DNA in brain and heart via magnetic capture and real-time PCR assay, and presence of DNA in feces using a real-time PCR with melt curve analysis. We detected antibodies against T. gondii and DNA in tissues in 24% and 19% of lynx, respectively. One lynx was positive for DNA of T. gondii in feces, which could indicate intestinal infection and potential for shedding oocysts. Our results indicate that lynx may be a useful sentinel species for monitoring environmental circulation of T. gondii in northern boreal regions and may pose a risk for transmission to other wildlife and to people handling or consuming lynx.
Wave propagation in laminated composite plates

A stiffness method has been used in this article to study dispersive wave propagation in a laminated anisotropic plate. The advantage of this method is in its usefulness in obtaining numerical results for the dispersion characteristics of waves propagating in a plate with an arbitrary number of arbitrarily anisotropic laminae. This method has been applied here, as a way of illustration, to a plate made up of transversely isotropic laminae with the axis of isotropy of each lamina lying in the plane of the lamina. Results thus obtained are shown to agree well with the exact solutions for isotropic and transversely isotropic single layered plates. Numerical results are presented for cross‐ply (0°/90°/0°) laminated composite plates and show that the frequency spectrum in this case differs considerably from that for a single layered (0°) plate.
Debiasing System 1: Training favours logical over stereotypical intuiting

Whereas people’s reasoning is often biased by intuitive stereotypical associations, recent debiasing studies suggest that performance can be boosted by short training interventions that stress the underlying problem logic. The nature of this training effect remains unclear. Does training help participants correct erroneous stereotypical intuitions through deliberation? Or does it help them develop correct intuitions? We addressed this issue in four studies with base-rate neglect and conjunction fallacy problems. We used a two-response paradigm in which participants first gave an initial intuitive response, under time pressure and cognitive load, and then gave a final response after deliberation. Studies 1A and 2A showed that training boosted performance and did so as early as the intuitive stage. After training, most participants solved the problems correctly from the outset and no longer needed to correct an initial incorrect answer through deliberation. Studies 1B and 2B indicated that this sound intuiting persisted over at least two months. The findings confirm that a short training can debias reasoning at an intuitive “System 1” stage and get reasoners to favour logical over stereotypical intuitions.
