A Review of Performance Management in State-owned Enterprises and Private Enterprises in China

In order to improve profits, the theory of enterprise performance management has formed a corresponding theoretical framework and system. Enterprises can improve performance management methods based on their own situation. This research compares the differences between state-owned enterprises and private enterprises through literature review. The existing papers mainly focus on performance feedback and communication mechanisms, the application of performance management and corporate strategy, and the enthusiasm of employees to participate in performance management. The existing papers mainly focus on performance feedback and communication mechanisms, the application of performance management in line with company strategies, and the initiative of employees to participate in performance management. Neglecting the specific role of state-owned enterprises and not combining performance management with their social responsibility. In addition, the imperfect performance indicator system has also led to the problem of not being greatly influenced by subjective factors within the enterprise. The accuracy of performance evaluation in many enterprises is often influenced by human factors. The design of performance management evaluation indicators is not scientific, the evaluation is unfair, the concept of human resource management is lack of correctness, strategic planning, single evaluation results, ineffective use, lack of follow-up, and frequent communication in performance management; The recruitment and allocation of personnel are unreasonable, the construction of the management system is highly arbitrary, and there is a significant subjective bias in performance evaluation.

Influence of progressive spectacles correction on the eye hydrodynamics indicators and ocular morphometric parameters in presbyopic persons

Purpose: To study the eye hydrodynamics indicators and eye morphometric parameters in presbyopic subjects with emmetropia and hyperopia under the usual professional visual load with using of progressive and monofocal spectacles correction. Material and methods: 49 subjects (98 eyes) of 4556 y.o., mean age (48 1.7) years, were examined. There were 20 men and 29 women. Emmetropia was present in 22 subjects (44 eyes), mild degree of hyperopia in 19 subjects (38 eyes) and moderate degree of hyperopia in 8 subjects (16 eyes). All subjects who were included in the study had not any eye diseases other than presbyopia and hyperopia. All persons were examined against the background of intense visual load at the end of the working day. First examination was performed without spectacles using, second one after prescribing and using of monofocal or progressive spectacles correction. The examination methods were represented by visometry, refractometry, pneumotonometry, computer tonography, ultrasound biometry, determination of accommodation amplitude using the Push up test, optical coherence tomography of the anterior segment of the eye. Results: The critic intensity of eye hydrodynamics processes, anterior chamber depth decreasing and the iridocorneal angle increasing were revealed under conditions of visual load at near distance in presbyopic patients with hyperopia and emmetropia without spectacles correction. Using of progressive spectacles correction led to significant decreasing of intraocular pressure (IOP) (p 0.001), increasing of aqeous humor outflow (p 0.001), anterior chamber depth decreasing (p 0.01 in emmetropia and p 0.001 in hyperopia) and iridocorneal angle increasing (p 0.001). Significant increasing of the accommodation amplitude was recorded with using of progressive correction in both hyperopic (p 0.001) and emmetropic subjects (p 0.05). Conclusion: The use of progressive glasses as a permanent correction has a positive effect on the state of eye hydrodynamics and morphometric parameters of the anterior chamber in emmetropic and hypermetropic patients with presbyopia. Lack of correction in persons of presbyopic age not only causes visual fatigue, but can lead to disruption of hydrodynamic balance and the development of glaucoma.

Eyeglass correction: influence on the morphometric parameters of the anterior chamber and the eye hydrodynamics in presbyopes with hyperopia

The work of accommodative apparatus has a regulatory effect on the hydrodynamics of eye and it is involved in ensuring the normal outflow of intraocular fluid (IOF). Age-related weakening of accommodation leads to a deterioration in the state of hydrodynamics, and especially significant shifts are expected in patients with axial hyperopia in the anatomical boundaries of “short” eye.Purpose. To evaluate the effect of correction with progressive lenses and monofocal ones on hydrodynamic indicators and certain morphometric parameters of the anterior chamber in presbyopic patients with hyperopia under conditions of long-term habitual professional eye strain.Material and methods. 25 subjects (50 eyes) of 44–55 y. o. (mean age 47 ± 1,6 years) were examined in January-July 2022. There were 8 males and 17 females with presbyopia and hyperopia. All patients were examined at the end of their working day: the first examination was performed in the initial state without correction, the second one − under using correction with monofocal lenses (control group) or progressive ones (main group). The examination methods included visometry, autorefractometry, pneumotonometry, ultrasound biometry, computerized tonography, determination of accommodation amplitude using the push-up test, optical coherence tomography of the eye anterior segment.Results. The critic tension of hydrodynamics, the decreasing of anterior chamber depth and iridocorneal angle width were revealed in presbyopic hyperopic patients under the conditions of eye strain at a near distance without correction with eyeglasses. Using of correction with progressive lenses led to significant increasing of the accommodation amplitude (p < 0,001), decreasing of IOP (p < 0,001), increasing of aqueous humor outflow (p < 0,001), deepening of the anterior chamber (p < 0,001) and increasing of the iridocorneal angle width (p < 0,001) compared to the initial state. No significant changes in these parameters were revealed in the users of monofocal lenses compared to the initial state.Conclusion. Using of progressive lenses as a permanent correction has a positive effect on ocular hydrodynamics and morphometric parameters of the anterior chamber in presbyopic hyperopes. Lack of correction in hyperopic patients of presbyopic age not only causes of eye fatigue but also can lead to disruption of hydrodynamic balance and development of glaucoma.

Lithium-Ion Battery State-of-Charge Estimation Using Electrochemical Model with Sensitive Parameters Adjustment

State-of-charge (SOC) estimation of lithium-ion (Li-ion) batteries with good accuracy is of critical importance for battery management systems. For the model-based methods, the electrochemical model has been widely used due to its accuracy and ability to describe the internal behaviors of the battery. However, the uncertainty of parameters and the lack of correction from voltage also induce errors during long-time calculation. This paper proposes a particle filter (PF) based method to estimate Li-ion batteries’ SOC using electrochemical model, with sensitive parameter identification achieved using the particle swarm optimization (PSO) algorithm. First, a single particle model with electrolyte dynamics (SPME) is used in this work to reduce the computational burden of the battery electrochemical model, whose sensitive parameters are selected through the elementary effect test. Then, the representative sensitive parameters, which are difficult to measure directly, are adjusted by PSO for a high efficiency. Finally, a model-based SOC estimation framework is constructed with PF to achieve accurate Li-ion battery SOC. Compared with extended Kalman filter and equivalent circuit model, the proposed method shows high accuracy under three different driving cycles.

Клінічна характеристика обстежених пацієнток із безпліддям та перенесеним пренатальним стресом

The purpose of the study was to go thoroughly into a question about the clinical features of the history and reproductive status in women with psychoemotional disorders associated with prenatal stress in comparison with the clinical features of the history and reproductive status of somatically healthy women with tubo-peritoneal factor infertility. Materials and methods. The study involved 120 patients, 80 of whom experienced prenatal stress: the main group, which was divided respectively into group 1 – women who underwent in vitro fertilization and group 2 – women who did not undergo in vitro fertilization. For comparison, a control group of 40 women without prenatal stress was formed. The age of the patients ranged from 22 to 45 years. Complaints, medical and life history, gynecological history, educational level were studied in all patients, and the causes of infertility were assessed. Results and discussion. Among the causes of primary infertility, hypothalamic-pituitary-ovarian insufficiency and associated ovulatory changes, which are manifested by menstrual irregularities, are dominant. Persistent anovulation, lack of correction of menstrual irregularities lead to the development of endocrine-dependent gynecological diseases, one of the manifestations of which is primary infertility. The frequency of infertility with a regular menstrual cycle is 30-70%. In these patients, combined forms of infertility are more common. The study found that in terms of place of residence, social status, the presence of bad habits, gynecological history data, infertile patients in vitro fertilization programs do not differ from healthy women with tubo-peritoneal factor of infertility. A significant difference was revealed between the indicators of the nature of the menstrual cycle in the comparison groups. It was found that a menstrual cycle lasting less than 23 days is a predictor of decreased functional activity of the hypothalamic-pituitary-ovarian axis in women. Analysis of the hormonal regulation of the reproductive function of the examined groups of women established the prevalence of follicle-stimulating hormone indices in the main group over the control group (9.6 ± 0.2 versus 6.2 ± 0.1 mMod / ml, respectively, p <0.05), and the thyroid-stimulating hormone level had no differences between comparison groups. We proposed to distinguish 3 states of ovarian reserve – normal, low and extremely low for women with infertility and a history of prenatal stress. Conclusion. Timely comprehensive assessment of the state of the endocrine system, the state of the ovaries in relation to the state of the regulatory mechanisms of psychoemotional adaptation of women with infertility associated with prenatal stress, which we studied, requires a partial revision of approaches to this group of patients and the timely use of in vitro fertilization to improve the effectiveness of infertility treatment

Integrated Decision Making Aided Model to Estimate the Risks of the Excavation System

For the last years, a bibliometric examination of risk evaluation approaches for excavating systems has been presented in this publication. To develop an early warning system, it's essential to compile a list of possible dangers that can arise during excavation. Failure Mode and Effects Analysis (FMEA) is a useful approach. Traditional risk assessment techniques have been criticized for a variety of reasons, including a lack of correlation between risk variables, difficult arithmetic operations, and a lack of correctness and preciseness in the evaluations. A unique method of risk analysis in FMEA that uses digraphs and matrix approaches underneath the Pythagorean fuzzy scenario is presented in this research. To get started, we'll defy Pythagorean fuzzy numbers in a triangle form. Both language terminology and risk factor data and information are expressed using them (inclusive of occurrence, severity, and detection). The Pythagorean fuzzy digraph thus captures the interrelationships between the risk variables and the relative importance of each one, as seen in the figure. After that, we create a Pythagorean fuzzy test indicated for each identified failure mode and compute risk priority indexes to determine risk priorities. Using a metro station excavation as a case study, the accuracy of risk assessments in excavation is improved.

Pancreatic lesion in children with nephrotic syndrome

Nephrotic syndrome occupies one of the leading places among kidney diseases in children. Scientific studies indicate that edema syndrome, arterial hypertension, disorders on the microcirculatory level occurring in case of nephrotic syndrome contribute to the slowing and reduction of blood flow in the pancreas, which leads to the development of hypoxia and metabolic disorders. Under conditions of metabolic and microcirculatory disorders, as well as against the background of the therapy used in children with nephrotic syndrome the risk of secondary pancreas lesion increases significantly. Pathogenetic treatment of nephrotic syndrome involves the administration of glucocorticosteroid and cytostatic therapy. The study of autopsy materials of the pancreas in children who died of glomerulonephritis revealed histomorphological changes in 35.7% of children in the form of acute interstitial pancreatitis and pancreonecrosis. At the same time there are still few works in the scientific literature, devoted to the study of functional state of the pancreas in children with kidney diseases. The data on pancreatitis prevalence in children are extremely inconsistent. Significant variation in the frequency of pancreatic lesion in children (from 5 to 25%) is most often associated with diagnostic difficulties. Ultrasound examination after a meal (postprandial test) allows to diagnose pancreatic pathology (indirect signs of chronic pancreatitis, reactive pancreatic changes) with higher accuracy (by 23%) than traditional examination. Late diagnosis of pancreatic lesion and lack of correction can significantly affect patients’ health and quality of life. There is a need to study functional state of pancreas in children with nephrotic syndrome to improve understanding of pathogenesis of possible involvement in pathological process and optimization of preventive and therapeutic tactics.

Effect of His bundle pacing on right bundle branch block located distal to site of pacing

BackgroundIt is generally accepted that bundle branch block (BBB) may be corrected simply by selective His bundle pacing (S-HBP) distal to site of block. However, clinical HBP is often non-selective (NS), the site of block unknown and moving the HB lead is not always an option. Thus, while correction of right (R) BBB in NS-HBP has been reported, its mechanism is unknown. MethodsThreshold testing was done during His bundle pacing in 39 patients with RBBB. We compared NS-HBP and S-HBP and analyzed the role of pacing voltage and capture threshold of the parallel pathway, in partially or completely correcting RBBB. ResultsDuring NS-HBP, higher pacing voltage completely corrected RBBB in 22/35 patients as compared to 5/18 patients at lower voltage. Remaining patients showed incomplete correction of RBBB. NS-HBP group with lower capture threshold of 1.3 ± 0.5 V completely resolved RBBB in 9/14 vs 3/11 patients in NS-S HBP group with higher capture threshold of 2.4 ± 0.8 V. QRS activation time in NSHBP was 91 ± 8 ms (baseline 97 ± 7 ms p = ns). S-HBP resolved RBBB in only 1/21 patients. Conclusions1.) Lack of correction with S-HBP suggests that RBBB was distal to site of HBP and yet was corrected with NS-HBP. 2.) Voltage dependent correction of RBBB in NS-HBP suggests that conduction via a specialized parallel pathway maintains normal ventricular activation time. 3.) Correction of RBBB in all patients with NS-HBP, suggests that conduction block was either bypassed or right ventricular free wall pre-excited by conduction via parallel pathway.

The impact of associated tenotomies on the outcome of incomplete phalangeal osteotomies for lesser toe deformities

BackgroundPartial or incomplete osteotomy (IO) of the phalanx is recently described in the literature. However, the clinical outcome and the rate of complications when applied to lesser toe deformities (LTD) have been never addressed. This study aims to find out if the association of tenotomies to incomplete or partial phalanx osteotomies has a significant impact on the clinical outcomes, the occurrence of complications, and the recovery time after surgery.MethodsA retrospective review of two cohorts of cases operated in our institution for hallux abductus valgus (HAV) and associated LTD from 2008 to 2014 was carried out. The surgical correction of both HAV and the associated LTD was always performed by minimally invasive techniques. The study included a total of 223 patients (723 IO in 556 toes). In 129 cases, the IO for LTD correction was performed without tenotomies, and in 94, the procedure was combined with flexor and/or extensor tenotomies. Patients were assessed with the American Orthopaedic Foot and Ankle Society (AOFAS) questionnaire before surgery and at 6- and 12-month follow-up.ResultsThe mean preoperative AOFAS score before surgery was similar in both cohorts. At 12-month follow-up, the cohort without tenotomies showed better recovery (95.7 ± 2.8 versus 92.5 ± 6.8; p < 0.01). AOFAS scores decreased as the number of associated LTD increased (r = − 0.814; p < 0.001). Cases operated on by PO + tenotomy showed a high rate of complications such as delayed union of the osteotomy (p < 0.01), hypertrophic callus (p < 0.01), phalangeal fracture at the osteotomy site (p < 0.01), and lack of correction (p < 0.05). The overall occurrence of adverse events was 38.6% in cases operated by PO + tenotomy and 13.9% in cases receiving PO alone (p < 0.0001). Cases operated on without tenotomy showed a shorter time to complete recovery for daily life activities (37.4 ± 2.3 versus 43.0 ± 1.7 days; p < 0.01).ConclusionThe performance of associated tenotomies to incomplete phalanx osteotomies provides worse clinical outcomes, higher complication rates, and longer recovery time as compared to similar forefoot surgeries without tenotomies.Trial registrationThe study was based on retrospectively registered data starting on May 24, 2008.

Seven-year follow-up for malrotation of a radial diaphysis fracture in a child corrected by osteotomy for loss of motion: A case report.

A greenstick fracture is an incomplete fracture where the compressive side of the cortex is still intact but plastically deformed. The incidence of poor results following the closed treatment of greenstick fractures in children >10 years of age is seriously underestimated. Therefore, fixing the position of the forearm is important for initial treatment. In cases of greenstick fracture, the possibility of inadequate remodeling of angulated deformities during growth, and in particular, the lack of correction between rotational malalignment and growth when the diaphyseal forearm is involved in the fracture, should be considered. A male, 10-year-old, left hand-dominant, Asian patient fell while playing in the garden and was immediately assessed by an orthopedic doctor at an Emergency Orthopaedic Clinic. Initial examination revealed a deformity of his dominant left forearm and an angulated greenstick fracture of the radius. However, after 3 months, he developed loss of supination of his left forearm and complained of limitation of left forearm supination. Radiography demonstrated a volar angulation of 20°. The patient underwent open reduction, internal fixation and 10° bending with a plate for correction without corrective rotation. At 12 months after injury, the patient did not exhibit pain or limitation of the elbow and wrist. After follow-up for 7 years, the patient was able to perform normal day-to-day activities with no adverse symptoms. The present case indicated that corrective osteotomy is required following the loss of supination after a greenstick fracture of the diaphysis of the radius. The patient of the current study exhibited rotation due to the central band of the interosseous membrane. In the treatment of greenstick fractures, a radius apex angulation of 20° must be corrected via osteotomy due to loss of rotation. The present case indicated that corrective osteotomy of the radius apex alone without rotational correction, in combination with plate bending improved the loss of forearm rotation.

Optimizing Pedicle Subtraction Osteotomy Techniques: A New Reduction Plier to Increase Technical Safety and Angular Reduction Efficiency.

Pedicle subtraction osteotomy (PSO) is a technically demanding surgery. There is room for development of osteotomy reduction instruments like the one we present in this study, to better guide angular correction and closure of the osteotomy line. To present a new surgical instrument that optimizes PSOs of the thoracolumbar spine. Seventeen consecutive patients have been treated at 3 different European University Hospitals. All underwent a PSO of the lumbar spine to treat major sagittal imbalance. The amount of vertebral angular correction needed was calculated using the full balance integrated (FBI) method. A special plier, which allows to safely control the angular correction, was used intraoperatively. Preoperative and early postoperative global sagittal balance parameters were compared. The mean preoperative calculated correction angle (FBI) was 33.8°; the mean postoperative correction obtained was 32.1°. Lumbar lordosis was statistically greater than preoperatively (55.8° vs 19.4°, P<.0001). The global sagittal balance was improved, as shown by the increase of the spino-sacral angle from 122° preoperatively to 128° postoperatively (P=.0547). None of the patients had an intraoperative or early postoperative neurologic complication. There were no mechanical intraoperative complications during correction nor at the first postoperative follow-up. The advantages of the instrument are safe, precise, and efficient reduction, by a rotation of the pedicle screws close to the osteotomy line, thus avoiding collapse and lack of correction, complications usually seen with the conventional technique. Further prospective studies are needed to confirm these results.

Analysis of Isolated Photons in Photoproduction in PYTHIA

Collision of particles at high energies at accelerators is the main source of data used to obtain deeper understanding of the fundamental interactions and the structure of the matter. Processes of isolated photon production have provided many tests of theoretical descriptions of the universe on scales smaller than the proton. This work is dedicated to the analysis of the large amount of collision data that has been accumulated at ZEUS in 2004-2007 period and new methods of processing isolated photons that have been proposed. The authors develop software algorithms that allow obtaining the signal of isolated photons from the data collected on the ZEUS detector at electron-proton collider HERA, calculating the differential cross sections, and comparing the measured data with PYTHIA Monte Carlo predictions. Taking into account the features of the ZEUS detector, the photon signal is separated from the background events and the number of isolated photons is calculated. Computational mathematical and numerical methods have been used to simulate the interaction of particles in the detector. Monte Carlo predictions for differential cross sections as functions of the pseudorapidity and transverse energy of the photon ηg, ETg and the jet ηjet, ETjet, and the fraction of the photon momentum хgmeas carried by the interacting parton have been calculated and compared with the experimental data. The results of the study are compared with the previous studies and show for the first time that all isolated photon HERA measurements are consistent with each other. New results show improved uncertainties. The formation of isolated inclusive photons and photons with the accompanying jet was measured in photoproduction with ZEUS detector at HERA collider using the integrated luminosity of 374 ± 7 pb-1. For the first time, more complex Monte-Carlo simulation models of isolated photons for ZEUS detector were generated and applied, and the description of the photon signal was improved. It has been found that PYTHIA describes the shape of the cross section as a function of ηg well enough, but does not fully reproduce the shape of ETg, ETjet, and the middle region of хgmeas, while ηjet is described not very well. The reason for this discrepancy can be the lack of corrections of higher orders in the predictions for cross sections of direct photons. Scaling of the cross sections obtained with PYTHIA improves the description of ETg and ηg. The unsatisfactory description of ηjet indicates that further studies are required.

Urinary infection by Morganella morganii in a young dog affected by ectopic ureter

Urinary tract infections (UTI) are frequent diseases in the routine of clinical medicine of companion animals and bacterial cystitis is the most common cause of UTI in dogs and cats. The bad-formations of the urinary tract, as the ectopic ureter, may predispose the affected animals to recurrent urinary infections caused by the same or different pathogens. Morganella morganii is a bacterium with rare isolation from urinary infections in dogs, and it is considered an opportunistic agent in infectious processes, both in pets as in men. This report aimed to describe the clinical diagnosis, as microbiological diagnosis of this infrequent isolation of this microorganism in a young animal carrier of ectopic ureter. Despite of previous treatments of cystitis, the patient had no clinical improvement due to the lack of correction of the baseline cause, or ectopic ureter; which favored recurrent infections. Even being warned about the diseases and its aggravating, the owner left the treatment of the patient, despite the partial clinical improvement with antibiotic therapy according to the susceptibility profile. The results obtained in this case report confirm the importance of culture and sensitivity test for treatment of UTIs; and the search for baseline causes of infectious processes of the urinary tract. Although it’s rare isolation, Morganella morganii should be considered as an important causative agent of UTI in animals as in humans, since the anatomical deformities favor the rise of pathogens, especially Gram negative inhabitants of the gastrointestinal tract of animals.

RisaAligner software for aligning fluorescence data between Agilent 2100 Bioanalyzer chips: Application to soil microbial community analysis.

Ribosomal Intergenic Spacer Analysis (RISA) is a high-resolution and highly reproducible fingerprinting technique for discriminating between microbial communities. The community profiles can be visualized using the Agilent 2100 Bioanalyzer. Comparison between fingerprints relies upon precise estimation of all amplified DNA fragment lengths; however, size standard computation can vary between gel runs. For complex samples such as soil microbial communities, discrimination by fragment size is not always sufficient. In such cases, the comparison of whole fluorescence data as a function of time (electrophoregrams) is more appropriate. When electrophoregrams [fluorescence = f (time)] are used, and more than one chip is involved, electrophoregram comparisons are challenging due to experimental variations between chips and the lack of correction by the Agilent software in such situations. Here we present RisaAligner software for analyzing and comparing electrophoregrams from Agilent chips using a nonlinear ladder-alignment algorithm. We demonstrate the robustness and substantial improvement of data analysis by analyzing soil microbial profiles obtained with Agilent DNA 1000 and High Sensitivity chips.

Error correction mechanisms in social networks can reduce accuracy and encourage innovation

Humans make mistakes but diffusion through social networks is typically modeled as though they do not. We find in an experiment that high entropy message formats (text messaging pidgin) are more prone to error than lower entropy formats (standard English). We also find that efforts to correct mistakes are effective, but generate more mutant forms of the contagion than would result from a lack of correction. This indicates that the ability of messages to cross “small-world” human social networks may be overestimated and that failed error corrections create new versions of a contagion that diffuse in competition with the original.

Quality control of surface-consistent deconvolution on land dynamite data

Seismic data with reliable amplitude and phase can significantly impact drilling programs by providing valuable descriptions of the reservoir and overburden, especially for complicated or subtle plays. Processing steps such as velocity tomography and amplitude-preserving migration are critical for producing high-quality seismic images, but equally important are surface-related premigration processing steps that can significantly alter seismic amplitude and phase information, such as deconvolution. During land dynamite seismic acquisition, source and receiver responses are affected by surface conditions and inhomogeneous weathering layers. For example, even with the exact charge size, the response from each shot can vary greatly as the medium around the charge changes. Receiver recordings are affected similarly by near-surface conditions. An improper correction or a lack of correction for near-surface anomalies during seismic preprocessing will reduce the subsurface resolution and negatively bias subsurface descriptions that are dependent on reliable amplitude and phase information. Surface-consistent deconvolution can help to attenuate surface-consistent biases. There are several ways to quality-control (QC) this processing step. Different consequences result from various choices of deconvolution parameters.

Attention deficit hyperactivity disorder in children

Attention deficit hyperactivity disorder (ADHD) is a common neuropsychological disorder occurring in 5-8% of school-aged children. In case of late diagnosis and lack of correction, this condition may lead to intra-family problems and formation of antisocial behavior, which largely determines the relevance of the research into ADHD. The main clinical manifestations of ADHD include attention deficit, hyperactivity and impulsivity, as well as symptoms of staticolocomotory deficiency. The pathogenesis, diagnosis, and treatment of ADHD are discussed.

Innovation from Imitation: Error Correction in Networks Reduces Accuracy and Promotes Innovation

An enormous body of scholarship examines how social contagions spread over social networks. But despite the fact that humans make mistakes, diffusion through social networks is typically modeled as though information is relayed with perfect fidelity. As a result, little is known about how errors, the robustness of message formats, and attempts to correct errors, impact the spread of contagions. We find in an experiment using human subjects that compact (high entropy) message formats, such as text messaging pidgin, are more prone to error than more expansive (lower entropy) formats, such as standard English. We also find that while efforts to correct mistakes improve the accuracy of individual messages, over time they paradoxically generate a wider variety of mutant forms of the contagion than would result from a lack of correction. This indicates that the ability of messages to cross even “small- world” human social networks may be overestimated and that models of social contagion and diffusion are biased...
