Published: October 2024

AbstractIn this study, polymer blends of polythiophene (PTH) and poly(vinylidene fluoride) (PVDF) are investigated by focusing on their structural and electrochemical characteristics. These blends displayed immiscibility confirmed through field emission scanning electron microscopy (FE‐SEM) and interaction assessments. PTH's role as a plasticizer is evident, diminishing crystallinity. A rise in PTH level led to a lower glass transition temperature and a higher melting point, suggesting reduced intermolecular forces and increased polymer chain flexibility. Conversely, a dispersed phase presence elevated the melting point, restricting chain movement and crystallization. The thermal properties of blends are enhanced by increased PTH content. Applying the Vogel–Tammann–Fulcher model to ionic conductivity measurements, it observed a direct relationship between temperature and free volume, impacting conductivity and ion transport numbers. Certain materials exhibit increased activation energies, indicating substantial thermodynamic barriers to local motion. Higher PTH content within the PVDF matrix notably increased the lithium ion transfer number from 0.22 to 0.71, a change tied to the C–S–C structure of polythiophene. However, elevated PTH levels also led to diminished negative charge transfer and ionic conductivity in the PTH‐PVDF blend compared to pure PVDF, likely due to an ionic conduction hindrance.
Anthropomorphic Sad Expressions Reduce Waste of “Single” Imperfect Food

Published: October 2024

ABSTRACTPoint‐of‐sale anthropomorphism—attributing human characteristics to nonhuman entities—has been shown to increase evaluations of food that deviates in shape or form from consumer expectations (“imperfect food”). However, while previous research has included the use of primary emotions to manipulate anthropomorphism, it is unclear whether depicting imperfect produce with happy or sad emotional expressions is more effective in boosting choice of such produce. This research addresses this gap and additionally examines a novel type of imperfection: when produce is torn off the bunch it normally comes in. A field study conducted at a large food retailer in Germany revealed that sales of “single” bananas significantly increased when they were anthropomorphized with sad emotions compared to when they were anthropomorphized with happy emotions or not anthropomorphized. Across three preregistered online experiments, this research corroborates the effectiveness of sad emotional expressions in boosting purchase intentions, establishes compassion as the underlying process, generalizes this effect to other produce (i.e., tomatoes), and shows that a price discount eliminates this effect. The findings of this research are particularly relevant for food retailers aiming to increase purchases, and thus reduce waste, of fresh produce that has become a loose “single.”
Choice, Psychological Ownership, and Option Valuation
Authors: Chan Eugene Y. 
Published: October 2024

ABSTRACTIn the past few decades, there have been concerns of a possible “choice overload effect” in that the provision of more (vs. less) choice might decrease choice satisfaction as it increases the difficulty of selecting an option among many. However, beyond choice satisfaction, there are other outcomes of offering more choices worth investigating. We examine another potential outcome of offering more choices. The results from four experiments suggest that offering more choice increases the chooser's valuation of the chosen option, relative to offering less choice. This is because offering choice increases the chooser's psychological ownership of the chosen option, a premise derived from prior conceptualizations of choice as fostering control. Thus, we extend theoretical understanding of the consequences of offering choice beyond satisfaction, while at the same time offer implications for marketers interested in understanding the benefits—in addition to the potential harms—of offering choice for consumers.

AbstractPotential applications of colloidal polymer nanoparticles in the preparation of smart inks are investigated by physical incorporation of the oxazolidine molecules. Precise adjusting the polymer chain flexibility and polarity is achieved by controlling the ratio of methyl methacrylate and butyl acrylate monomers in the polymerization reaction. In addition, nanofibrous indicators of acid–base vapors are prepared from the latex nanoparticles. This can be beneficial for creating materials that sense and respond to environmental changes, such as humidity or moisture and acidity. Thermochromic inks are prepared by microencapsulating crystal violet lactone dye (CVL) in polymer matrices to prevent their release into the aqueous media. Combining two distinct systems with varying triggers, such as light and temperature, provides an effective strategy for double‐encryption anticounterfeiting and crack and scratch detection and indication applications. Preparing labels impregnated with double‐responsive inks, a novel approach is developed for food spoilage detection and preservation indication. Labels are manufactured using polymer nanoparticles, which contain photoluminescent oxazolidine molecules, as well as a trinary mixture of CVL within core–shell latex particles as the thermochromic dye. The combination of these two responsive elements transforms traditional packaging into a dynamic and interactive sentinel for the food it holds.
Green Advances in Wet Finishing Methods and Nanoparticles for Daily Textiles
Authors: Patti Antonella 
Published: October 2024

AbstractThis work presented an overview of greener technologies for realizing everyday fabrics with enhanced antibacterial activity, flame retardancy, water repellency, and UV protection. Traditional methods for improving these qualities in textiles involved dangerous chemicals, energy and water‐intensive procedures, harmful emissions. New strategies are presented in response to the current emphasis on process and product sustainability. Nanoparticles (NPs) are suggested as a potential alternative for hazardous components in textile finishing. NPs are found to efficiently decrease virus transmission, limit combustion events, protect against UV radiation, and prevent water from entering, through a variety of mechanisms. Some attempts are made to increase NPs efficiency and promote long‐term adherence to textile surfaces. Traditional wet finishing methods are implemented through a combination of advanced green technologies (plasma pre‐treatment, ultrasound irradiations, sol‐gel, and layer‐by‐layer self‐assembly methods). The fibrous surface is activated by adding functional groups that facilitate NPs grafting on the textile substrate by basic interactions (chemical, physical, or electrostatic), also indirectly via crosslinkers, ligands, or coupling agents. Finally, other green options explore the use of NPs synthesized from bio‐based materials or hybrid combinations, as well as inorganic NPs from green synthesis to realize ecofriendly finishing able to provide durable and protective fabrics.

AbstractExcited‐state intramolecular proton transfer (ESIPT)‐associated dual‐state emissive aliphatic dual‐light emitting conducting polymers (DLECPs) having oxidation‐reduction capacities are prepared polymerizing 2‐acrylamido‐2‐methylpropane‐1‐sulfonic acid, methacrylic acid, and 2‐methyl‐3‐(N‐(2‐methyl‐1‐sulfopropan‐2‐yl)acrylamido)propanoic acid monomers. Of as‐synthesized DLECPs, nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopies, fluorescent enhancements (I/I0), and computational investigation indicate intriguing photophysical features in DLECP3 (optimum composition). In DLECP3, ─CONH─, ─CON<, and ─COOH subluminophores are recognized by density‐functional theory (DFT)/time‐dependent‐DFT calculations and experimental investigations. ESIPT‐associated dual‐state emission/conductivity, aggregation‐enhanced emissions, selective opto‐electronic responses toward Hg(II)/Cr(III) at 437/574 nm, and redox properties of DLECP3 are supported by solid‐state/solution spectroscopies, time‐correlated single photon counting (TCSPC) measurements, dual‐state excitation dependent emissions, microscopic images, electrochemical measurements, and DFT calculations. Here, preferential interaction of Hg(II)/Cr(III) with DLECP3 (amide)/DLECP3 (imidol) and reduction/oxidation of Hg(II)/Cr(III) to Hg(I)/Cr(VI) are substantiated by UV–vis, FTIR, and X‐ray photoelectron spectroscopies; TCSPC measurements; NMR‐titration; electrochemical studies; alongside computational calculations. The proton‐electrical conductivities of DLECP3, Hg(II/I)‐DLECP3, and Cr(III/VI)‐DLECP3 in solids/solutions are 15.27 × 10−5/6.16 × 10−5, 19.60 × 10−5/25.52 × 10−5, and 26.69 × 10−5/27.60 × 10−5 S cm−1, respectively.
A neuromuscular clinician's guide to magnetic resonance neurography
Authors: Pitman Jenifer , Fayad Laura M. , Ahlawat Shivani 
Published: October 2024

AbstractMagnetic resonance neurography (MRN) is increasingly used in clinical practice for the evaluation of patients with a wide spectrum of peripheral nerve disorders. This review article discusses the technical aspects of MRN highlighting the core sequences performed for clinical care. A robust, high‐resolution, heavily T2‐weighted fluid‐sensitive sequence performed on a 3.0 Tesla magnet system remains the main workhorse MRN sequence. In specific clinical scenarios, adjunct techniques such as diffusion‐weighted imaging can be added to a protocol for disease characterization. In addition, gadolinium‐based contrast material can also be administered for the purposes of image optimization (suppress adjacent vascular signal) and disease characterization. Technical modifications to field of view and planes of imaging can be made based on the clinical question and discussion with the radiologist(s). On fluid‐sensitive MRN sequences, a normal peripheral nerve exhibits iso‐ to minimally hyperintense signal relative to skeletal muscle with a predictable trajectory, preserved “fascicular” architecture, and tapered caliber from proximal to distal. Peripheral nerve abnormalities on MRN include alterations in signal, caliber, architecture, diffusion characteristics as well as enhancement and provide information regarding the underlying etiology. Although some MRN findings including nerve hyperintensity and long‐segmental enlargement are nonspecific, there are certain diagnoses that can be made with high certainty based on imaging including benign peripheral nerve tumors, high‐grade peripheral nerve injury, and intraneural ganglia. The purpose of this article is to familiarize a neuromuscular clinician with fundamentals of MRN acquisition and interpretation to facilitate communication with the neuromuscular radiologist and optimize patient care.

Abstract

Objective
To maximize harvest of hatchery steelhead Oncorhynchus mykiss and Pacific salmon Oncorhynchus spp. while reducing impacts to wild conspecifics, fishery managers rely on the ability of anglers to distinguish between the two. Fin erosion, including dorsal fin erosion, is a common result of hatchery rearing of juvenile salmonids. Since the 1980s, managers in the Pacific Northwest have utilized adult steelhead dorsal fin height as a regulatory control rule, requiring anglers to release steelhead with dorsal fins over a height threshold. This approach assumes that all or most hatchery fish have shorter dorsal fins than their wild counterparts. This study was designed to test this assumption.

Methods
We compared steelhead origin (hatchery or wild) determined using scale analysis and adipose fin clipping (hatchery n = 127, wild n = 71) with origin estimated using dorsal fin height.

Result
Overall, a static dorsal fin height threshold (2.25 in, 5.72 cm) correctly identified 90% of hatchery-origin steelhead but misidentified nearly half (44%) of wild fish as hatchery. Dorsal fin height of known hatchery fish correlated with fish length, indicating a weakness of using a static dorsal height threshold as a management tool. The accuracy of distinguishing wild fish improved, but only marginally (56–76%), using a classification model where dorsal fin height of known origin fish from this study was a continuous predictor of origin. In comparison, adipose fin status correctly identified 97% of unmarked fish as wild.

Conclusion
The low accuracy of the classification model and static dorsal fin height thresholds at distinguishing hatchery and wild steelhead due to a strong correlation between dorsal fin height and fork length and the high fork length variability of hatchery origin fish. Given the low cost and accuracy of adipose fin clipping and the potentially high conservation risk associated with misidentification, we recommend discontinuing the use of dorsal fin height as a harvest control rule for steelhead.
Fabrication of a Polyglycolic Acid Porous Microneedle Array Patch Using the Nonsolvent Induced Phase Separation Method for Body Fluid Extraction

Published: October 2024

ABSTRACTTraditional blood sampling is essential for early diagnosis and subsequent analysis, but the methods using hypodermic needles are painful and burdensome. Recently, a minimally invasive approach utilizing porous microneedles has been developed and various porous microneedle array patches (MAPs) composed of biodegradable polymers have been investigated. To address issues about low mechanical strength and liquid absorption with porous MAPs, we used polyglycolic acid (PGA) as it is a biodegradable and hydrophilic polymer with high mechanical properties. In this study, we established a nonsolvent‐induced phase separation (NIPS) method for the fabrication of PGA porous MAPs, as the porous MAPs can be fabricated by simply immersing the molds injected with PGA‐hexafluoro‐2‐propanol (HFIP) solution in nonsolvents. We achieved the maximum liquid absorption rate of 16 ± 8.2 × 10−2 µL/min per one microneedle using the PGA porous MAPs fabricated by using ethanol as nonsolvent and PGA concentration of 10% (w/w). Our study provides a comprehensive understanding of porous MAPs fabricated using PGA material as well as its characteristics regarding the structural and mechanical properties of PGA MAPs, with potential as a diagnostic device to substitute conventional hypodermic needles for interstitial fluid (ISF) sampling and diagnosis.
The impact of Secure Communities on the labor market outcomes of immigrant women
Authors: Bansak Cynthia , Pearlman Sarah , Sparber Chad 
Published: October 2024

AbstractThe United States deported nearly 400,000 unauthorized immigrants under the Secure Communities (SC) interior immigration enforcement program between 2008 and 2014. This paper uses variation in the intensity of deportations across immigrants’ country of origin and city of residence to assess the labor market consequences of SC on foreign‐born women. We find no effect on the total number of employed immigrant women, but both annual wages and the number of hours worked fell. Moreover, SC induced a shift toward occupations with lower average pay and education requirements, higher exposure to hazards, and less contact with others. This is consistent with a chilling effect in labor markets such that some foreign‐born women were willing to sacrifice better pay and working environments for the ability to avoid detection.

AbstractStudents’ sense of school belonging is associated with healthier psychological functioning and improved academic outcomes. Currently, most research on school belonging has been conducted in the United States, United Kingdom, Australia, and New Zealand, resulting in school belonging practices and interventions largely biased towards Western school systems and cultures. This study sought to identify Indian students' perceptions of teacher‐level and school‐level factors that could contribute to a sense of school belonging. Open‐ended survey questions were used to qualitatively explore how teacher‐ and school‐level practices contributed to the school belonging of 93 Indian students aged 12–19. Data analysis followed manifest content analysis, identifying themes within teacher‐level and school‐level domains of enquiry. Results reveal valuable insights into factors influencing school belonging from the students’ perspective. These findings can inform the development of targeted interventions to support Indian students in rebuilding their sense of school belonging, improving their wellbeing, and enhancing their academic success. The research also contributes to a broader understanding of school belonging practices and their cultural sensitivity, benefiting educators, policymakers, and researchers worldwide.
A microwave temperature sounder (MWTS)–microwave humidity sounder fusion cloud detection method for land data from the FengYun‐3D MWTS and its impact on error estimation
Authors: Mao Jiali , Qin Zhengkun , Li Juan 
Published: October 2024

AbstractThe presence of clouds greatly disrupting the estimation of observation errors in satellite data. Therefore, cloud detection is a necessary step in satellite radiance data assimilation, not only to identify clear sky data and cloudy data, but also, more importantly, to accurately specify observation errors in different scenarios during all‐sky data assimilation. However, the assimilation of the microwave temperature sounder‐2 (MWTS‐2) onboard the FengYun‐3D satellite has been restricted by the low accuracy of cloud detection due to the absence of low‐frequency channels, especially for land areas where complex underlying surface brings more difficulties to the identification of cloudy data. The microwave humidity sounder‐2 (MWHS‐2), which is designed for water vapor sounding, is usually equipped on the same satellite as MWTS‐2. The sensitivity of the MWHS‐2 to water vapor enables it to provide more accurate information about clouds over land. Based on the advantage of the two instruments measuring on the same platform, an effective cloud detection method for MWTS‐2 data over land is established in this study after collocating the data of the MWTS‐2 and MWHS‐2. The results show that the new method achieves a cloud detection rate exceeding 75%, with a significantly reduced false detection rate compared with the traditional scattering index method, which is decreased from 40% to approximately 26%. More importantly, in non‐precipitating cloud regions, the cloud index built by the new method has a significant linear correlation with the difference between observed and simulated brightness temperatures (OMB) of MWTS‐2 data. Statistical analysis reveals that the cloud index can be used to effectively rectify the systematic OMB bias caused by those clouds in non‐precipitation cloud areas, which demonstrates the promising application of this cloud index in all‐sky MWTS‐2 data assimilation over land.
