The Impact of Enterprise Resource Planning (ERP) Systems on the Audit Report Lag
Authors: Kim Jongkyum , Nicolaou Andreas I. , Vasarhelyi Miklos A. 
Published: July 2014

ABSTRACT
Prior research has shown that the implementation of ERP systems can significantly affect a firm's business operations and processes. However, scant research has been conducted on the relationship between ERP implementation and the timeliness of external audits, such as audit report lags. While some of the alleged benefits of ERP are closely related to removing impediments contributing to audit report lags, others argue that the complex mechanisms of ERP systems create greater complexity for control and audit. In this paper, we examine the relationship between ERP implementations and audit report lags. The test results indicate that overall, a firm's ERP implementation is negatively associated with audit report lag. However, this negative association is significant only at the fourth and fifth years after initial ERP implementation. These results imply that the use of ERP systems by client firms may help decrease the audit report lag, but it takes time for the full impact of the firms' accounting systems to be realized.

Introduction: In April 2006, the people of Nepal organised mass demonstrations demanding the restoration of democracy in the country. The ocular injuries that resulted during the riots that ensued, their pattern and the visual outcome of the injured have not yet been reported. Objective: To study the demographic profile, type, severity and the visual outcome of ocular injuries that occurred during the 2006 people’s uprising in Nepal. Subjects and methods: This was a retrospective interventional series of cases involving 29 subjects. The main outcome measures were demography, laterality of injury, type of injury and the visual status before and after the trauma. Results: The age of the victims ranged from 14 to 32 years. Among the victims with eye injuries, 27 (93.1 %) were males, who were unemployed youth, students and construction workers. The left eye was injured more frequently than the right. Non-lethal bullets and explosive tear gas were the commonest agents of the major ocular injuries. The main types of injuries requiring hospitalization were closed globe injuries in eight victims and open globe in six. Surgical intervention was required in 57.2 % (n = 29) of the cases. The visual outcome was poor in cases of open globe injury with posterior segment involvement. Conclusion: Non-lethal bullets and explosive tear gases can cause significant visual impairment. Severe open globe injury with a retained intra-ocular foreign body is associated with significant visual loss. DOI: http://dx.doi.org/10.3126/nepjoph.v6i1.10775 Nepal J Ophthalmol 2014; 6 (2): 71-79
L’Humour noir des Lumières: Diderot, Casanova, Freud
Authors: Leborgne Erik 
Published: July 2014

RÉSUMÉ La critique récente sur les procédés du comique s’est beaucoup intéressée à l’ironie, au mot d’esprit, au persiflage, mais beaucoup moins à la pratique de l’humour et du Galgenhumor dans les œuvres du XVIIIe siècle. La littérature à la première personne (narrative, épistolaire, mémorielle) offre pourtant un riche matériau pour saisir le mécanisme psychique de l’humour noir à partir des concepts freudiens. Les textes de Denis Diderot et de Casanova témoignent d’une fine perception des ressources de l’humour et de son inscription littéraire, sur le plan de l’énonciation et du partage du mot humoristique avec le lecteur.

Authors: Xu Xiaofen , Liu Dongliang , He Daoping 
Published: July 2014

AbstractQuaternary ammonium surfactants 3a–d, with diether linkages in the backbone between hydrocarbon chains and the ammonium head groups, were synthesized as potential soft-template agents for the preparation of mesoporous materials. Varying the length of their carbon chains was expected to control the pore sizes of the corresponding mesoporous materials prepared. The critical micelle concentration (CMC) and γcmc (surface tension of the CMC) of these surfactants were measured by surface tension method.

Published: July 2014

AbstractIn aqueous acidic media, picolinic acid, 2,3-dipicolinic acid, and 2,6-dipicolinic acid promoted Cr(VI) oxidation of lactose to lactobionic acid has been carried out at room temperature. A possible reaction mechanism, which is based on the kinetic results and the product analysis, has been proposed. The anionic surfactant sodium dodecyl sulphate (SDS) and nonionic surfactant Triton-X-100 (TX-100) accelerate the process while the cationic surfactant N-cetylpyridinium chloride (CPC) retards the reaction.
Cloud Point Extraction of Polycyclic Aromatic Hydrocarbons in Aqueous Solution with Nonionic Surfactants
Authors: Alibrahim Moussa 
Published: July 2014

AbstractA cloud point extraction (CPE) process using the two nonionic surfactants, Tergitol 15-S-9 and Tergitol 15-S-7, mixtures of secondary ethoxylated alcohols, to extract selected polycyclic aromatic hydrocarbons (PAHs) from aqueous solutions at 25°C was investigated. Cloud point temperatures (CPTs) of selected nonionic surfactants were studied against the effect of added electrolytes on their cloud points. Sodium iodide could increase the cloud points of selected nonionic surfactants, i.e., the salt-in effect, whereas sodium chloride, sodium phosphate and sodium sulfate could decrease the cloud point, i.e., the salt-out effect. Cloud point temperatures (CPTs) of these micellar solutions were regulated and reduced enough with addition of sodium phosphate and sodium sulfate, so that the cloud point extraction (CPE) process could be facilitated at 25°C. It was found that a higher preconcentration factor could be achieved in the micellar solution having a lower surfactant concentration. The average preconcentration factor was also discussed as a function of surfactant concentration used in the CPE process.

Authors: Farkhani Dariush , Khalili Ali Asghar , Mehdizadeh Ali 
Published: July 2014

AbstractSulfosuccinate esters are vastly used in different formulations as wetting agents and dispersants. Hemi-ester, diester, ethoxylated, and ethoxylated ester derivatives of maleic anhydride, maleic acid, and fumaric acid are converted to the saturated or corresponding sulfosuccinates by the reaction of the double bond with sodium bisulfite in basic media. The roles of anionic, cationic and non-ionic surfactants have been investigated. Appropriate surfactants have been applied in the absence of a peroxide initiator. The results obtained show increased reaction rates. Characterization of the products was performed by FTIR and 1H-NMR spectroscopy. Ethoxylated isooctyl maleate derivative was used as the starting material and the sulfonation agents used were sodium bisulfite and meta bisulfite.

Published: July 2014

Abstract
All freshwater fish sampling methods are biased toward particular species, sizes, and sexes and are further influenced by season, habitat, and fish behavior changes over time. However, little is known about gear-specific biases for many common fish species because few multiple-gear comparison studies exist that have incorporated seasonal dynamics. We sampled six lakes and impoundments representing a diversity of trophic and physical conditions in Iowa, USA, using multiple gear types (i.e., standard modified fyke net, mini-modified fyke net, sinking experimental gill net, bag seine, benthic trawl, boat-mounted electrofisher used diurnally and nocturnally) to determine the influence of sampling methodology and season on fisheries assessments. Specifically, we describe the influence of season on catch per unit effort, proportional size distribution, and the number of samples required to obtain 125 stock-length individuals for 12 species of recreational and ecological importance. Mean catch per unit effort generally peaked in the spring and fall as a result of increased sampling effectiveness in shallow areas and seasonal changes in habitat use (e.g., movement offshore during summer). Mean proportional size distribution decreased from spring to fall for white bass Morone chrysops, largemouth bass Micropterus salmoides, bluegill Lepomis macrochirus, and black crappie Pomoxis nigromaculatus, suggesting selectivity for large and presumably sexually mature individuals in the spring and summer. Overall, the mean number of samples required to sample 125 stock-length individuals was minimized in the fall with sinking experimental gill nets, a boat-mounted electrofisher used at night, and standard modified nets for 11 of the 12 species evaluated. Our results provide fisheries scientists with relative comparisons between several recommended standard sampling methods and illustrate the effects of seasonal variation on estimates of population indices that will be critical to the future development of standardized sampling methods for freshwater fish in lentic ecosystems.

IMPORTANCEThe association between obesity and response to cancer treatment and survival remains unclear, with conflicting findings from various studies. The optimal choice between conventional chemotherapy and immunotherapy for first-line treatment remains uncertain in patients with obesity who potentially have an inadequate therapeutic response to immunotherapy.OBJECTIVETo investigate whether body mass index (BMI) modifies the association of immunotherapy or conventional therapy with overall survival in patients with advanced non–small cell lung cancer (aNSCLC).DESIGN, SETTING, and PARTICIPANTSA retrospective cohort study, using administrative claims data obtained from advanced treatment centers in Japan, was conducted between December 1, 2015, and January 31, 2023. Participants included individuals aged 18 years or older with aNSCLC who received immunotherapy, using immune checkpoint inhibitor (ICI) treatment or conventional chemotherapy.EXPOSUREImmune checkpoint inhibitor therapy as first-line chemotherapy was compared with conventional chemotherapy, identified through patient medical records.MAIN OUTCOMES AND MEASURESThe main outcome was overall survival. Survival analysis covered a 3-year follow-up period after the first-line chemotherapy.RESULTSA total of 31 257 patients with aNSCLC were identified. Of these, 12 816 patients received ICI therapy (mean [SD] age, 70.2 [9.1] years; 10 287 [80.3%] men) and 18 441 patients received conventional chemotherapy (mean [SD] age, 70.2 [8.9] years; 14 139 [76.7%] men). Among patients with BMI less than 28, ICI therapy was associated with a significantly lower hazard of mortality (eg, BMI 24: hazard ratio [HR], 0.81; 95% CI, 0.75-0.87) compared with those who underwent conventional chemotherapy. However, no such association was observed among patients with BMI 28 or greater (eg, BMI 28: HR, 0.90; 95% CI, 0.81-1.00).CONCLUSIONS AND RELEVANCEThe findings of this retrospective cohort study suggest that BMI modifies the association of ICI therapy compared with conventional chemotherapy with overall survival in patients with aNSCLC. A lack of association between ICI therapy and improved survival in patients with aNSCLC and overweight or obesity compared with conventional chemotherapy was observed. This suggests that ICI therapy may not be the optimal first-line therapy for patients with overweight or obesity and the use of conventional chemotherapy should also be considered in such patients.

AbstractPrinting human tissues and organs replete with biomimetic vascular networks is of growing interest. While it is possible to embed perfusable channels within acellular and densely cellular matrices, they do not currently possess the biomimetic architectures found in native vessels. Here, coaxial sacrificial writing into functional tissues (co‐SWIFT) is developed, an embedded bioprinting method capable of generating hierarchically branching, multilayered vascular networks within both granular hydrogel and densely cellular matrices. Coaxial printheads are designed with an extended core–shell configuration to facilitate robust core–core and shell–shell interconnections between printed branching vessels during embedded bioprinting. Using optimized core–shell ink combinations, biomimetic vessels composed of a smooth muscle cell‐laden shell that surrounds perfusable lumens are coaxially printed into granular matrices composed of: 1) transparent alginate microparticles, 2) sacrificial microparticle‐laden collagen, or 3) cardiac spheroids derived from human induced pluripotent stem cells. Biomimetic blood vessels that exhibit good barrier function are produced by seeding these interconnected lumens with a confluent layer of endothelial cells. Importantly, it is found that co‐SWIFT cardiac tissues mature under perfusion, beat synchronously, and exhibit a cardio‐effective drug response in vitro. This advance opens new avenues for the scalable biomanufacturing of vascularized organ‐specific tissues for drug testing, disease modeling, and therapeutic use.

AbstractLight‐induced ferroelectric polarization in 2D layered ferroelectric materials holds promise in photodetectors with multilevel current and reconfigurable capabilities. However, translating this potential into practical applications for high‐density optoelectronic information storage remains challenging. In this work, an α‐In2Se3/Te heterojunction design that demonstrates spatially resolved, multilevel, nonvolatile photoresponsivity is presented. Using photocurrent mapping, the spatially localized light‐induced poling state (LIPS) is visualized in the junction region. This localized ferroelectric polarization induced by illumination enables the heterojunction to exhibit enhanced photoresponsivity. Unlike previous reports that observe multilevel polarization enhancement in electrical resistance, the device shows nonvolatile photoresponsivity enhancement under illumination. After polarization saturation, the photocurrent increases up to 1000 times, from 10−12 to 10−9 A under the irradiation of a 520 nm laser with a power of 1.69 nW, compared to the initial state in a self‐driven mode. The photodetector exhibits high detectivity of 4.6×1010 Jones, with a rise time of 27 µs and a fall time of 28 µs. Furthermore, the device's localized poling characteristics and multilevel photoresponse enable spatially multiplexed optical information storage. These results advance the understanding of LIPS in 2D ferroelectric materials, paving the way for optoelectronic information storage technologies.

AbstractConsidering the increasing demand for personalized surgical care, as well as current healthcare resources limitations, the use of anatomical accurate 3D physical phantoms is becoming increasingly important for the training of surgeons and the test of surgical instruments. A lack of physical models is nowadays denoted regarding the training in electrosurgery, despite its wide diffusion in medical practice. This work reports an extensive characterization of electrosurgical physical phantoms fabricated with tissue‐mimicking ionogels and hydrogels. A careful design of the conductive gels allow the fine tuning of their mechanical and electrical properties, in order to match those of biological tissues. The manufacturing of a novel multi‐material skin stratification bench‐top pad is reported together with its use for training in both cold and electrical surgery. Furthermore, a feasibility study is reported, showing the use of conductive ionogels for simulating the coagulation of cortical vessels during brain surgery.

AbstractLateral Flow Assays (LFAs) are cost‐effective and widely utilized for rapid diagnostics, yet they often suffer from limited sensitivity. This study introduces a straightforward yet highly effective method to enhance LFAs performance by integrating a poly(ethylene glycol) diacrylate (PEGDA) hydrogel to create a “reaction trap.” This hydrogel reaction trap optimizes the flow rate and reaction time at the sensing components, substantially improving assay performance. By applying various hydrogel concentrations (6%, 9%, 12%, 15%, and 18% w/v), significant enhancements across a range of detection systems are achieved. An optimized 18% hydrogel concentration shows a 1.5 times increase in sensitivity in the tested commercial pregnancy test. Additionally, 12% hydrogel concentration is tested in pregnancy, ovulation, and Coronavirus disease 2019 (COVID‐19) commercial kits, and the improvement reached up to a sevenfold increase in signal intensity. The enhancement in detection illustrates the profound impact of this simple modification and shows the importance of hydrogel concentration optimization to maximize detection improvement. These results demonstrate that hydrogel‐coated LFAs offer a scalable and highly effective solution for boosting the reliability and sensitivity of rapid diagnostics across different healthcare settings, with broad potential for global health diagnostics applications.

AbstractFlexible crystalline solids exhibit unique properties in response to external stimuli like heat and light. However, challenges exist in developing crystalline solids that have similar degrees of flexibility as in solution. Herein, we report the preparation of the new flexible crystalline metal complex [Cd(CF3SO3)2(4‐spy)4] (4‐spy=4‐styrylpyridine), which contains photoreactive 4‐spy ligand. Unlike traditional solids, this metal complex displays solution state‐like [2+2] photocycloaddition reactivity. Specifically, UV irradiation of the crystalline material leads to formation of the same diverse array of dimers and cis isomer that are generated by photoreaction in the solution state. In addition, the photoresponsive flexibility of the solid leads to a photosalient effect and photo‐induced formation of pores. The origin of the solution state‐like photoreactivity of the solid is related to properties of the Cd(II) cation and fluorinated CF3SO3 anion, and the multi‐orientational arrangement of the 4‐spy ligands.
Development of an Impinging Jet Microreactor Synthesis Process for Surfactant‐Free Pt‐Nanoparticles as PEMFC Catalyst Component

Published: August 2024

AbstractColloidal, surfactant‐free platinum nanoparticles were prepared via a self‐built continuous impinging jet microreactor synthesis process in alkaline aqueous methanol solution (Co4CatTM process). In these syntheses, methanol functions as a reducing agent as well as an additional solvent. Especially the synthesis of surfactant‐free nanoparticles remained challenging, and additionally, the transfer of this synthesis into a continuous process required several optimization steps. In this contribution we present highly controllable final particle sizes by adjusting process temperature, platinum precursor concentration and molar ratio of the hydroxide and platinum precursor used. The size objective of the surfactant‐free Pt nanoparticles was a range of 1 – 10 nm, due to the intended application in various catalytic processes, especially as PEMFC electrocatalyst. Dynamic light scattering (DLS), ζ‐potential measurements, transmission electron microscopy (TEM) and UV/Vis spectroscopy were used to monitor the particle stability over a certain period of time and study the rate of the reduction reaction in more detail.
