Online group buying behavior: A study of experiential versus material purchases
Authors: Agarwal James , Das Gopal , Spence Mark T. 
Published: July 2022

AbstractMore than 50 million consumers participate in online group buying, hence its importance to retailers cannot be ignored. Four studies are conducted to determine (a) whether customers' preferences to participate in group buying relative to buying alone are more in the case of experiential (vs. material) purchases; (b) underlying psychological mechanisms affecting an individual's willingness to invite additional buyers; and (c) the moderating role of analytic versus holistic thinking orientation within the mediational framework. Consistent with expectations, preferences to invite additional buyers to receive a further discount (vs. buying alone and taking the deal‐of‐the‐day) were greater for experiential purchases than material purchases. Three psychological motivators, namely social relatedness, conversational value, and anticipatory enjoyment, act as parallel mediators. Finally, moderated‐mediation analysis shows holistic thinking accentuates the mediational pathway of anticipatory enjoyment but not for social relatedness, whereas analytical thinking accentuates the mediational pathway of conversational value. Of practical relevance to those designing group buying websites is that offering an additional discount to buyers if they are willing to expend the effort to form a larger group not only reduced the number of individuals indicating that they would not make a purchase at all, but about a quarter of respondents indicated that they would endeavor to find additional buyers. In addition, there is a clear preference for experiential goods; and for material goods, the findings suggest drawing attention to the experiences that material goods offer.

AbstractObjectivesTo review the referral and clinical characteristics of adult patients diagnosed with lysosomal storage diseases (LSD) through the Undiagnosed Diseases Network (UDN).MethodsRetrospective review of both application and evaluation records for adults admitted to the UDN with a final diagnosis of a lysosomal storage disease.ResultsTen patients were identified. Final diagnoses included late onset Tay Sachs, attenuated MPS I, MPS IIIA, MPS IIIB, and MPS IIIC. Most patients presented with neurocognitive changes. Prior to referral, all patients had been evaluated by neurology, four patients underwent phenotype specific panel testing that did not include the causative gene, and four patients had non‐diagnostic clinical exome sequencing.ConclusionsLSDs figure highly in the differential diagnosis of neurometabolic disorders in pediatric onset progressive diseases. In adults, their subtle initial presentations overlap with symptoms of more common disorders and less practitioner awareness may lead to prolonged diagnostic challenges.

Authors: Yang Kansheng , Song Zhe , Gielis Johan , Caratelli Diego 
Published: July 2022

AbstractA Super‐Formula‐based compact ultra‐wideband (UWB) printed monopole antenna is proposed in this paper. The presented design is implemented by using inexpensive FR‐4 laminates, and is optimized so as to enable excellent radio frequency performance in terms of impedance matching, realized gain, total efficiency, radiation pattern characteristics, maximal group delay variation, and system fidelity factor (SFF), while covering the Federal Communications Commission UWB channel 5, from 6.24 to 6.74 GHz, and channel 9, from 7.74 to 8.24 GHz. The proposed antenna solution has been characterized both passively and actively using a commercially available indoor real‐time positioning system, which relies on the phase‐difference‐of‐arrival algorithm. The collected measurement results demonstrate the high accuracy in real‐time positioning achieved with the developed antenna both in terms of distance and angle.

Authors: Moshobane Moleseng Claude , Olowoyo Joshua O. , Middleton Lorraine 
Published: July 2022

Societal Impact StatementOpuntia ficus‐indica, commonly known as prickly pear, is a widely distributed plant originating in central America. Its wide distribution and popularity as a cultivated plant are due to the sweetness of its fruits. Here, the role of O. ficus‐indica in the livelihoods of people in Limpopo Province, South Africa, was investigated. Roadside traders of prickly pear were surveyed 2019–2020 using paper‐based questionnaires and a convenience sampling strategy. Evidence of O. ficus‐indica trading as a means to generate income was uncovered. Notably, none of the traders knew about invasive species. Future studies should seek to understand the motivations of purchasers. The extent to which rural communities use this species for food security and poverty alleviation is not fully understood.Summary

The Opuntia ficus‐indica (whose fruits are traded in South Africa) is a species that is classified according to the National Environmental Management: Biodiversity Act (10/2004) Alien and Invasive Species (NEM:BA A&IS) regulations as an invasive species. This study sought to provide an understanding of the socio‐economic value of O. ficus‐indica and the characteristic profiles of the people who trade with O. ficus‐indica in the Limpopo Province of South Africa.
A convenience sampling strategy was conducted along trading roads in Limpopo province, and the data were collected by surveying traders' attitudes toward the prickly pear trade using questionnaires.
Our findings show that at the time of sampling 72 traders participated in prickly pear trading along the roadside. Unemployment is cited as the primary reason for their involvement in trading. O. Ficus‐indica is an important fruit for rural communities in Limpopo province. It helps communities living below the poverty line to generate income and to support their livelihoods.
Our study highlights the need for the establishment of a Prickly Pear Traders' Agency in order to promote the trade of O. ficus‐indica as a measure to generate income, alleviate poverty, and ensure food security. The paper concludes with recommendations for local government support for O. ficus‐indica traders through the formalization of the trade and through monetary support.
Firewater fuel tank integrity under blast loads from vapor cloud explosions
Authors: Paschal Tyler , Sharma Amandeep 
Published: July 2022

AbstractMany firewater systems employ diesel fuel pumps that require nearby diesel storage tanks. If a flammable release and subsequent vapor cloud explosion (VCE) occurs near a firewater pumping station, it is important to understand the impact that the blast load will have on the fuel tanks. This presentation describes an evaluation of the blast response of 350‐gal diesel fuel tanks 80% filled with water to simulate a nearly full diesel tank. The tanks were elevated 6 ft above grade. The deflagration load generator (DLG) test rig was used to impose blast loads of 1–10 psig and 50–180 psi‐ms on a 3 × 3 fuel tank array. Each row of three tanks was rotated to different orientations with respect to the blast load: parallel (face‐on), 45°, and 90° (side‐on). Pressure gauges and high‐speed video recorded the blast loads and dynamic response of the fuel tanks. The results indicate that, depending on orientation and blast load, the tank support structures may undergo plastic deformation and translate in space during loading, although the tanks were still functional post‐test under the blast loads imposed in these tests. A limited comparison between response predictions made using finite element analysis and the test data is provided.
Left truncation in linked data: A practical guide to understanding left truncation and applying it using SAS and R

Published: July 2022

AbstractTime‐to‐event data such as time to death are broadly used in medical research and drug development to understand the efficacy of a therapeutic. For time‐to‐event data, right censoring (data only observed up to a certain point of time) is common and easy to recognize. Methods that use right censored data, such as the Kaplan–Meier estimator and the Cox proportional hazard model, are well established. Time‐to‐event data can also be left truncated, which arises when patients are excluded from the sample because their events occur before a specific milestone, potentially resulting in an immortal time bias. For example, in a study evaluating the association between biomarker status and overall survival, patients who did not live long enough to receive a genomic test were not observed in the study. Left truncation causes selection bias and often leads to an overestimate of survival time. In this tutorial, we used a nationwide electronic health record‐derived de‐identified database to demonstrate how to analyze left truncated and right censored data without bias using example code from SAS and R.

Published: July 2022

AbstractAn ultrasonic‐assisted dispersive liquid–liquid microextraction method for the simultaneous detection of four bisphenols (BPs) in plastic packaging beverages was established. The recoveries of the four BPs of spiked water solution were 89.0%–106.7%. The standard deviations (Ss) (n = 9) were 1.7%–2.0%. The recoveries of the 4 BPs in the real honey sample at three concentration levels ranged from 87.6% to 97.5%, and the Ss (n = 6) ranged from 1.0% to 2.3%. The method was employed to detect the 4 BPs (BPA, BPS, BPF, and BPAF) in plastic packaging drinking water, soda water, and honey samples. In drinking water samples, BPS was found in 8 out of 13 samples with a maximum concentration of 1.36 μg/L; BPA was found in four samples, and the maximum concentration was 1.08 μg/L. In soda samples, BPS was detected in six out of the eight samples with the maximum concentration of 27.44 μg/L; 11.40 μg/L BPA was detected in one sample; BPAF was detected in one sample and the concentration was below the limit of quantification. In 13 honey samples, BPF was detected in 12 samples, and the maximum concentration was 766.7 μg/kg; BPS was detected in six samples and the maximum concentration was 209.0 μg/kg; BPAF was detected in eight samples, and the maximum concentration was 197.7 μg/kg; BPA was detected in two samples, but the concentrations were all below the LOQ. Compared with other methods reported, the established method was simple, effective, and eco‐friendly.
EPA's detection methods, the drinking water treatability database, and innovative technologies for PFAS remediation
Authors: Kuzniewski Saleha 
Published: July 2022

AbstractPer‐ and polyfluoroalkyl substances (PFAS) are a large group of highly fluorinated, aliphatic chemicals detected throughout the environment, including in human serum. Several regulatory milestones have been achieved in the United States for these environmentally toxic chemicals linked to health problems in humans, the latest one being the US Environmental Protection Agency's (EPA's) PFAS Strategic Roadmap necessitating detection and remediation of PFAS. This article, in addition to briefly discussing these regulatory milestones, evaluates the EPA's detection methods for PFAS including EPA Methods 533, 537.1, and 8327 and other methods currently under development such as the total organic fluorine (TOF) and total organic precursor (TOP) methods. The article also mentions the methods used by other federal agencies for PFAS quantitation. The EPA's drinking water treatability database (TDB) is also described along with the advantages and challenges of the effective treatment methods for PFAS. Most of these treatment methods in the EPA's drinking water TDB face the challenge of disposing wastes containing PFAS, an issue not faced by innovative technologies, and some of these innovative technologies are also discussed. This article will help to understand the current status on the detection and remediation technologies for PFAS treatment in soil and water. It is imperative to have these technologies ready to assist with the remediation objectives in the PFAS Strategic Roadmap.
Recent advances in the investigation of a slow‐moving landslide in the Three Gorges Reservoir area, China
Authors: Wang Shun , Li Dian‐Qing , Du Wenqi 
Published: July 2022

AbstractMany slow‐moving landslides in the Three Gorges Reservoir (TGR) area exhibit episodic movement patterns in response to variations in the reservoir water level and seasonal rainfall. These landslides are typically characterized by pre‐existing shear zones composed of thick, clay‐rich layers that are sensitive to hydrological forcings. The residual shear strength of these shear zones is believed to control the dynamic movements of these landslides. In this article, we review the recent advances in the investigation of a large slow‐moving landslide, the Huangtupo landslide, in the TGR area. This landslide has been chosen as a benchmark for studying similar landslides in this area. This review focuses mainly on the research carried out by the authors and their collaborators over the last 5 years on topics including the landslide mechanisms and forcings, rheological behaviors and constitutive models of the landslide materials, the numerical simulation of clastic shear‐zone soils, and the effects landslide‐induced tsunamis would have on the ships in the reservoir. In addition, new perspectives and challenges for future research on slow‐moving landslides are provided.

Published: July 2022

AbstractSelenylation is an important modification strategy of polysaccharide, however, one of the main obstacles is that the weak esterification ability of selenide reagent, which leads to the low Se conversion efficiency during reaction. Here, we used N‐methyl‐2‐pyrrolidone hydrosulfate ([HNMP]HSO4) as acid catalyst efficiently synthesized selenized guar gum (Se‐GGs) to improve the activity of selenide reagent. The chemical structure of GG and selenized derivatives was investigated using FT‐IR, 1D/2D NMR spectrometry and atomic force microscopy (AFM). The results indicated that selenite groups existed in Se‐GGs and the substitution position was at C6. Furthermore, it was also demonstrated that [HNMP]HSO4 had a dual influence on GG by increasing the Se content (from 181.3 to 9072.8 μg/g) and regulating the molecular weight, which was due to strong Brönsted acidic proton (H+). These results illustrated a new synthetic method for preparing functional polysaccharides with a broad range of potential applications.

Published: July 2022

AbstractMononuclear PdII complexes bearing mixed MIC/Py/PPh3 donor set ligands are presented starting from a bis‐triazolium salt featuring 4,4’‐substitution pattern of central biphenyl ring. The mononuclear PEPPSI (pyridine enhanced precatalyst preparation, stabilization and initiation) type complexes bearing triazolylidene donor ligand have been synthesized via an unusual Csp2‐Csp2 decoupling reaction. The complexes have been characterized by 1H, 13C{1H} NMR spectroscopy and mass spectrometry. Two of the complexes have also been structurally characterized by single crystal XRD. All the complexes appeared as active precatalysts in α‐arylation of amide and Suzuki‐Miyaura coupling reactions. Catalytic outcomes clearly indicate the superior activities of the PdII complexes with mixed MIC/PPh3 donor set ligands compared to the corresponding PEPPSI type complexes in α‐arylation of oxindole.

AbstractWe contribute with the design and synthesis of novel 2,3‐diphenyl‐2H‐indazole hybrids series (1–14). Compounds 4 and 6 had the highest antiproliferative activity against the cancer cell lines, HeLa, SK‐LU‐1, K‐562, PC‐3, SW620 and MCF‐7 (CC50 values from 3 to 5.4 μM). Their activity was also evaluated against a normal human cell line, showing their higher Selectivity Index against the cancer cell lines than the reference drug CA‐4. The inhibition of tubulin assembly by compounds 4 and 6 was determined using in vitro tubulin polymerization assay and Western Blotting. The induction of mitotic catastrophe was observed with immunofluorescence assays. Besides, it was demonstrated by flow cytometry that compounds 4 and 6 arrest HeLa cell cycle at G2/M and promote apoptotic cell death. The mitotic arrest was also associated with elevated levels of cyclin B1 protein. We have identified two hybrids that behave as microtubule‐destabilizing agents on different cancer cell lines.

Published: July 2022

AbstractThin‐film lithium niobate platform, namely lithium‐niobate‐on‐insulator (LNOI), brings new opportunities for integrated photonics, taking advantages from both outstanding crystalline properties and special structural features. The excellent properties of LNOI have triggered development of a variety of on‐chip photonic devices for light generation and manipulation. However, as an indispensable component for photonic circuit with full functionalities, the thin‐film photodetector lacks in portfolios of LNOI‐based devices due to standing obstacles of low electrical conductivity and poor photoelectric conversion ability. Here, a self‐powered broadband LNOI photodetector based on enhanced photovoltaic effect, benefitting from encapsulated plasmonic nanoparticles and doped silver ions, is reported. Maximum responsivity of 0.25 A W−1 and detectivity (1.56 × 1014 Jones) are achieved. First‐principle calculations and electric‐field simulation reveal intrinsic mechanisms and crucial roles of plasmonic nanoparticles and silver ions on photocurrent generation and collection. This work opens an avenue to develop high‐performance on‐chip LNOI photodetectors, offering a conceivable means toward multiple‐functional photonic circuits.
Performance‐based plastic design and seismic performance evaluation of twisted diagrids with shear links
Authors: Song Sirui , Zhang Chonghou 
Published: July 2022

SummaryTwisted diagrid tube structures have become popular due to their significant lateral resistance and esthetic potential. However, the ductility and energy dissipation capacity of twisted diagrid structures are poor. This paper presents a seismic resilient fused structural system named the twisted diagrids with shear links (TDSL), and the performance‐based plastic design (PBPD) method is introduced for designing a 24‐story prototype structure. The numerical model of the TDSL prototype is established, then nonlinear static and dynamic analyses are conducted to evaluate the seismic behavior of the prototype. The results reveal that the TDSL system can significantly improve the post‐yield performance compared to the conventional twisted diagrid structure, and the performance objectives are achieved properly. Subsequently, incremental dynamic analyses are carried out to investigate the collapse fragility of the TDSL prototype, and the collapse risk of the prototype is assessed by FEMA P695. The results indicate that the TDSL prototype has satisfactory collapse‐resisting capacity under earthquakes. It is also found that corner columns can improve the seismic safety of the prototype against collapse. In general, the TDSL system is an appealing choice for twisted buildings in seismic regions.
