Consumer reactions to nudity in print advertising: Comparing same‐gender and opposite‐gender effects

It is often assumed that exposure to nude stimuli in advertising influences consumer behavior positively. However, the empirical evidence concerning the effects of nudity on consumer reactions is inconclusive. The goal of this study is to disentangle the effects of opposite ‐ gender and same ‐ gender nudity on female and male consumers' reactions. This study, thereby, offers a framework for the appropriate choice of seminude or fully clothed human stimuli based on advertisers' objectives and consumer – model gender interactions. The empirical data were derived from a large ‐ scale market research initiative from Germany with 61,399 consumer evaluations of 147 real ads from 16 product categories. Female consumers show positive same ‐ gender results for both seminude and fully clothed female models, indicating strong homophily, but nonsignificant opposite ‐ gender effects on information search, positive attitude change, integration of brand into consideration set, and purchase intentions. In contrast, male consumers demonstrate a significantly positive and equally strong influence of opposite ‐ gender and same ‐ gender seminude stimuli on all of the four variables.
Our rights are carved in stone: the case of the Pathalgadi movement in Simdega, Jharkhand

ABSTRACT In recent years, indigenous movements and rights-based struggle has become a focal point of research on resistance. In the context of India, Adivasi struggles in pre- and post- colonial times have been centered on the issues of jal, jangal and jameen (water, forest and land). In 2018, what became known as the Pathalgadi movement emerged in various villages in the state of Jharkhand. Pathalgadi, a traditional practice of erecting stone slabs for various purposes, was refurbished as a means to claim rights to local-level democracy and management of resources. This paper explores the strategies of resistance employed by the movement in Simdega district, where the raising of Pathalgadis primarily focused on claiming forest rights through existing legislations. The first section seeks to situate forest governance and struggle in the region, revisiting contributions from subaltern theories to shed light on the current and historical context of resistance. Based on four empirically driven categories of resistance, the second section brings forward an analysis of the movement, demonstrating how resistance occurred primarily through legal means, with strong discursive elements. As such, the Pathalgadi movement is seen to be working within the letter of the law, merely claiming rights previously granted through legislation.
NOSE-TO-BRAIN DRUG DELIVERY: AN UPDATE TO THE ALTERNATIVE PATH TO SUCCESSFUL TARGETED ANTI-MIGRAINE DRUGS

The Blood-Brain Barrier (BBB) limits transportation to the brain of possible treatment moieties. Specific stimulation of the brain through olfactory and trigeminal neural pathways by BBB has been taken into consideration for the development of a wide spectrum of brain therapeutics. The intranasal delivery path delivers the drugs through the brain, eliminating any side effects and increasing neurotherapeutics performance. Diverse drug delivery systems (DDDss) for reaching the brain via the nasal route have been researched over the past few decades. Large-scale molecular biologics, such as Deoxyribonucleic acid (DNA), gene vectors, and stem cells, can be administered intranasally, as a method for the management of a range of CNS illnesses, including stroke, Parkinson's diseases, multiple sclerosis, Migraine, Alzheimer's diseases, epilepsy, and mental disorders. New DDSs, including nanoparticles, liposomes, and polymeric micelles, have acquired potentials in the nasal mucosa and central nervous system (CNS), as effective means of concentrating the brain without toxicity. Differential nasal cavity structures posed a significant obstacle in ineffective drugs beyond the nasal valve. Pharmaceutical firms have increasingly used emerging techniques for the production of new nasal pharmaceutical drugs to overcome these obstacles. This review aims to identify the new advances in the nasal administration of brain-based DDSs for Migraines.
Turning Rules into Resources: Worker Enactment of Labor Standards and Why It Matters for Regulatory Federalism

Labor standards are not just enforced; they are enacted, and often in ways that are different from their stated intention. This distinction creates an opening to consider the ways that frontline workers extend and repurpose enforcement practices. Drawing on qualitative research in two US cities, the authors focus on Latino immigrant construction workers to identify the strategies they use to rework formal safety mandates to advance technical knowledge, create skill-based alliances across organizational hierarchies, and protect career trajectories. These resourcing strategies were present in both locations, but workers’ ability to affect the quality of their jobs through the collective enactment of labor standards varied significantly by city and depended on the enforcement practices in play. Workers’ attention to these localized resourcing opportunities suggests possibilities for progressive innovation at the multiple levels of government driving emerging research on regulation and federalism.
Hybrid electrical and optical neural interfaces

Neural interfaces bridge the nervous system and the outside world by recording and stimulating neurons. Combining electrical and optical modalities in a single, hybrid neural interface system could lead to complementary and powerful new ways to explore the brain. This convergent approach has gained robust and exciting momentum recently in neuroscience and neural engineering research. Here, we review developments in the past several years aiming to achieve such hybrid electrical and optical microsystem platforms. Specifically, we cover three major categories of technological advances: transparent neuroelectrodes, optical neural fibers with electrodes, and neural probes/grids integrating electrodes and microscale light-emitting diodes. We analyze examples of these probes tailored to combine electrophysiological recording with optical imaging or optical stimulation of the brain and discuss possible directions of future innovation.
Acetylene carbonylation over Ni-containing catalysts: role of surface structure and active site distribution

Heterogenization of homogeneous catalyst for acetylene carbonylation was carried out by preparing a series of Ni-modified catalysts (Ni-ZSM-5, Ni-IM-5 and Ni-MCM-41). Several important properties of the heterogeneous catalysts were determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES), XPS, XRD, N2 adsorption, pyridine-FTIR, SEM and TGA. Moreover, we used various activity criteria to dissipate perturbing factors, when we focused on the influence of surface structure and active site distribution. The result that Ni-IM-5 had the greatest TOFNi = 5107 g acrylic acid per g Ni per h showed that the surface structure of samples did not influence the catalyst performance significantly. In addition, the highest ratio of nickel sites/acid sites in Ni-MCM-41 represented the best active site distribution. Thus, Ni-MCM-41 has the highest TOFcat = 70.6 g acrylic acid per g cat. per h. Furthermore, stability testing of the catalysts showed the Ni-MCM-41 could be used four times, while others only twice.
The effect of otus social educational network on english achievement and attitudes of Iranian high school EFL learners

Abstract Educational networks become the most popular form of instructional technology during the past decades. The effect of this educational technology on the teaching English methodologies has been significantly increased all over the world. The main aim of this study was to investigate the effect of Otus social educational network on the English achievement of Iranian high school English as a foreign language (EFL) learners. It also attempted to find out students’ attitudes towards the use of Otus application. To this aim, fifty male language learners were selected based on convenience sampling as the participants of the study. While the lessons and assignments were presented through Otus in the experimental group, the students in the control group had a traditional class. Finally, to explore the learners’ attitudes towards the application of Otus, a questionnaire was used. It was found out that the application of Otus had a significant effect on the English achievement of Iranian first-grade high school EFL learners. The findings also indicated that students in the experimental group had positive attitudes towards Otus. This research adds its significant findings of the growth of online language teaching facilities and enhancing the attitudes and achievements of Iranian EFL learners. Results can lead to some pedagogical implications for Iranian English language policy-makers to consider the use of educational networks and online application in the syllabus and teachers’ training courses.
Are lignin-derived monomers and polymers truly sustainable? An in-depth green metrics calculations approach

The usage of renewable resources has become a hot topic upon the rising global awareness against fossil feedstock consumption. Lignin, the 2nd most abundant natural polymer on Earth, is an aromatic biomacromolecule that holds a tremendous potential for the synthesis of biobased materials. The production of monomers and polymers from lignin has been investigated for years and keeps on expanding, as proven by the flourishing literature. However, the sustainability of the synthetic reactions has not been systematically analyzed. Herein, green chemistry plays a vital role in this area and provides several tools to design eco-friendly production methods. This critical review first describes the preeminent approaches for the synthesis of biobased monomers and polymers from lignin-derived compounds. In the second part, the “greenness” aspects of the 175 key monomer synthetic methods and 32 polymerization methods are evaluated based on selected criteria, including waste generation, atom efficiency, energy efficiency, usage of safer solvents, and biocatalytic methodology. The accessible green metrics, such as environmental factor (E factor) and atom economy are calculated to measure the greenness and to provide a quantitative base for strategic decisions. Furthermore, this study provides insights for the improvement opportunities and lights up the room for further developments. This review, aiming at scientists, industries and investors, strives to provide a critical outlook for the existing synthetic methods and motivates researchers to call for the integration of sustainability factors.
Youth Farmers, Shocks and Food Security in Nigeria

Shocks are insufficiently handled in many developing countries, including Nigeria. At least 60percent of the farmers in Nigeria lack adequate safety net coverage to mitigate the effect of shocks. Thus, this study examines how shocks affect youth farmers and its possible effect on food security in Nigeria. This study makes use of Wave 4 (2018/2019) of the Living Standard Measurement Study-Integrated Survey on Agriculture (LSMS-ISA) data, applying the Propensity Score Matching (PMS) model and the two-sample t-test. Findings from the PSM showed that households affected by shocks are less food secure. This is validated from the two-sample t-test; which tests for the potential impact of shocks on household food security. The results showed that though a higher percentage of the households (94.42percent) are not affected by shocks, compared to those affected by shocks (2.58percent), but are worse-off by 0.007percent in terms food security. This means that households who are not affected by shocks are more food secured by 0.007percent. Therefore, based on the findings, it is recommended that appropriate measures be adopted by the Nigerian government, such as providing social protection, safety nets, credit facilities amongst others, to help increase agricultural productivity in order to sustain food security.
The influence of population agglomeration on air pollution: An empirical study based on the mediating effect model

With rapid urbanization and industrialization, the population of metropolis in China is increasing. Previous studies suggest that population agglomeration would have a significant impact on air pollution in cities. Using a panel dataset of 30 provincial capital cities during 2013-2017, as well as days of air quality equal to or above Grade II as air pollution indicators, the results show that an increase of population density will improve air quality in large cities. Through the mediation effect test, this paper found that tertiary industry is the mediation channel of population agglomeration to reduce air pollution. An increase of population density in big cities is conductive to increasing the proportion of tertiary industry, thereby reducing the proportion of seriously polluting secondary industry, and reducing air pollution.
Water flux responses of tropical trees and lianas to foliage loss caused by a heavy hailstorm

Large‐diameter hail is unusual in the lowland tropics; consequently, its impact on water flux responses of trees and lianas due to foliage loss is unknown. In December 2012, Xishuangbanna Tropical Botanical Garden (21°55′N) in southern Yunnan, China, experienced the most severe hailstorm in approximately 30 years, with hailstones of 8‐ to 17‐mm diameter falling for 10–30 min. We assessed the effect of this hailstorm on sap flux density (SFD) in response to foliage loss in six tree and three liana species. Among the trees, for a given atmospheric vapour pressure deficit (VPD), Tectona grandis and Dipterocarpus tuberculatus showed a significant reduction in sap flux density and water use during the post‐hailstorm week in comparison to pre‐hailstorm week. In contrast, a liana Ventilago calyculata showed a significant increase in SFD during the first post‐hailstorm week, whereas the other tree and liana species showed no significant change in their SFD and water use. T. grandis also showed visible wilting during the first 5 days post‐hailstorm. However, this tree species showed recovery from wilting and also no more reduction in SFD after ~7–9 days. D. tuberculatus also showed SFD recovery a week post‐hailstorm. We conclude that the impact of a heavy hailstorm on the water flux of tropical trees and lianas was mild or neglectable. Our study documented a rare severe hailstorm occurrence and its impact on ecosystem processes of tropical forest and enhances our understanding about water flux of tropical woody species exposed to hailstorm.
Identification and ordering of safety performance indicators using fuzzy TOPSIS: a case study in Indian construction company

PurposeThe purpose of this paper is to propose a practical framework to measure the safety performance of workers in the Indian construction industry. The key safety performance indicators are identified and ordered on the premise that the higher order assignment of an indicator implies a strong indication of an effective safety performance.Design/methodology/approachVarious indicators of safety performance in the construction industry were identified from extant literature review combined with author's personal viewpoint. The identified variables were inquired for appropriateness for the Indian construction scenario by consultation with experts. Fuzzy Technique for order preference by similarity to ideal solution (TOPSIS) technique was considered for the ranking of the indicators from most to least important.FindingsThe most important highlight of the study was the importance of the role of management by participating in informing workers about the safety rules and compliance toward safety measures. Proper and timely safety training to the workers and equipping them with sophisticated safety equipment for daily activities is perceived to be highly important in ensuring a safe and healthy workplace environment. Controlling the absenteeism rate reduces the burden of extra work on the employees, thereby, encouraging safe work-related behavior.Originality/valueSenior management should make safety induction programs compulsory at the time of joining of the employees. The guidelines for safety practices, rules and information about the safety equipment should be properly documented and arranged in safety manuals. Periodical drills involving visual demonstration of the safety practices should be followed to ensure safety at workplace.
Effects of Tailored Resistance Exercise Training in a Group of Metalworkers with Ergonomic or Manual Handlings Loads Prescription by the Occupational Physician: a Pilot Study

LEVEL OF EVIDENCE: 4 SUMMARY Background. Work-related musculoskeletal disorders (WRMSDs) are cause of disability and loss of productivity. Part of the workers suffers from WRMSDs while others are exposed to risk factors. Resistance training (RT) can reduce pain symptomatology, counteracting WRMSDs. The aim of this investigation is to evaluate the effectiveness of a RT program in a group of metalworkers on pain perception, disability and physical fitness in context of real work-setting. Methods. Eighteen metalworkers took part to a 12 weeks RT program with a personalized intervention during the sessions. Disability of the arm, shoulder and hand questionnaire (DASH) and the visual analogue scale for the low back (L-VAS) represent the primary outcome regarded. Handgrip strength, shoulder and hamstrings flexibility and cardiorespiratory endurance were tested. Pre-post differences were evaluated through T-test. Results. DASH score improved significantly of 4.28 points (p = 0.03). L-VAS did not change (p = 0.38) while physical fitness outcomes improved significantly except for the shoulder flexibility. Spontaneous attendance reached 83.42%. Conclusions. Pain and disability decreased in upper limb and shoulder but not in the lumbar spine. Moreover, physical fitness of participants improved. Considering the spontaneous attendance to the program of these participants, we exhort RT implementation in occupational primary and secondary prevention programs.
Experimental Studies of Droplet Formation Process and Length for Liquid–Liquid Two-Phase Flows in a Microchannel

In this study, changes in the droplet formation mechanism and the law of droplet length in a two-phase liquid–liquid system in 400 × 400 μm standard T-junction microchannels were experimentally studied using a high-speed camera. The study investigated the effects of various dispersed phase viscosities, various continuous phase viscosities, and two-phase flow parameters on droplet length. Two basic flow patterns were observed: slug flow dominated by the squeezing mechanism, and droplet flow dominated by the shear mechanism. The dispersed phase viscosity had almost no effect on droplet length. However, the droplet length decreased with increasing continuous phase viscosity, increasing volume flow rate in the continuous phase, and the continuous-phase capillary number Cac. Droplet length also increased with increasing volume flow rate in the dispersed phase and with the volume flow rate ratio. Based on the droplet formation mechanism, a scaling law governing slug and droplet length was proposed and achieved a good fit with experimental data.
A minimal thrust vectoring rotor with six degree of freedom: Design and analysis

Innovative Research Group Project of the National Natural Science Foundation of China, Grant/Award Number: 61621002; National Natural Science Foundation of China, Grant/Award Number: 61973270 Abstract This article presents a minimal thrust vectoring rotor (mTVR) with 6‐DoF motion ability. The mTVR is equipped with only three tiltable thrust units that deploy the coaxial counter‐propellers design for generating pure thrusts. Thus, the mTVR is able to perform 6‐DoF flight with decoupled translation and rotation based on the full rank Jacobian matrix. The geometry of the mTVR is optimised first, by studying the condition number of the Jacobian matrix that contains five geometry parameters. The overall system is then carefully modelled based on the actual hardware configuration of the mTVR prototype, including the coaxial counter‐propeller thruster, the high‐voltage servo for tilting, and the detailed multi‐rigid body motion dynamics of the vehicle. Next, the output envelop and dynamic response of the 6‐DoF actuator performance are evaluated. A 6‐DoF motion controller with disturbance rejection is designed and tested on a specialised multi‐ functional software platform developed for the mTVR. The controller shows good stability in regular, even aggressive operation of the vehicle.
Low-Profile Metasurface-Based Antenna With Tripolarization for 5G Applications

This article develops a novel low-profile meta-surface-based tripolarized antenna with complementary patterns for fifth-generation (5G) application. A shared aperture metasurface-based structure is first proposed, which is carefully studied by equivalent circuit models and field distribution. Then, to realize multiple polarization operation, the TM<sub>10</sub>, antiphase TM<sub>20</sub>, and TM<sub>00</sub> modes are used and excited by suitable feeding networks. For horizontal polarization, wideband response is realized by coupling and combining the TM<sub>10</sub>/TM<sub>20</sub> dual modes. An inductance-loaded TM<sub>00</sub> mode is displayed by loading the shorting vias on the metasurface, which is used to implement vertical polarization. Finally, a metasurface-based tripolarized antenna with a low profile of <inline-formula> <tex-math notation="LaTeX">$0.04\lambda _{0}$ </tex-math></inline-formula> (<inline-formula> <tex-math notation="LaTeX">$\lambda _{0}$ </tex-math></inline-formula> is the free space wavelength at 3.30 GHz) is fabricated. The overlapped 10-dB bandwidths for all excitations are from 3.26 to 3.84 GHz (16.3%) with isolation greater than 22 dB, which well covers the 5G-N78 band. The measured peak gain and radiation efficiency are larger than 10.3 dBi and −0.42 dB (90.8%), respectively. The results indicate that the proposed antenna with a low profile, a simple and low-cost configuration, multipolarization, good bandwidth, high radiation efficiency, and gain performance could be widely used in sub-6 GHz 5G communication systems.
Determination of Aflatoxin M1 in Milk by a Magnetic Nanoparticle-Based Fluorescent Immunoassay

ABSTRACT A sensitive and rapid magnetic nanoparticle-based fluorescent immunoassay for the determination of aflatoxin M1 in raw milk was developed. Aflatoxin M1 was converted to aflatoxin M1-o-carboxymethyl oxime. The aflatoxin M1-oxime was used for the preparation of aflatoxin M1-oxime-fluoresceinamine conjugate through the carbodiimide reaction. The aflatoxin M1-oxime-fluoresceinamine conjugate was characterized by ultraviolet–visible and infrared spectroscopy. Magnetic nanoparticles (Fe3O4) were synthesized and modified by 3-(aminopropyl)triethoxysilane. The size of initial (139 nm) and functionalized magnetic nanoparticles (147 nm) was determined by particle analysis. The optimal mass of immobilized antibody (25 µg) and optimal concentration of aflatoxin M1-oxime-fluoresceinamine conjugate (15 µg mL−1) for magnetic nanoparticle-based fluorescent immunoassay were determined. The developed immunoassay provided a linear aflatoxin M1 concentration range from 3.0 to 100 pg mL−1 in bovine milk. The detection limit was 2.9 pg mL−1. The results of aflatoxin M1 magnetic nanoparticle-based fluorescent immunoassay in heat-treated milk and phosphate-buffered saline at pH 6.6 were compared. The influence of the somatic cell count, pH, and fat concentration in bovine milk on the aflatoxin M1 immunoassay was investigated. The influence of the milk species on the immunoassay was also characterized. The high fat concentration ovine milk depressed the sensitivity of the aflatoxin M1 immunoassay.
