Wood-based cellulose nanocrystals as adsorbent of cationic toxic dye, Auramine O, for water treatment
No full text© 2020 Elsevier Ltd. All rights reserved. Removal of toxic organic cationic dye, Auramine O (AO), is critical prior to its discharge to the environment. In this work, wood-based colloidal cellulose nanocrystals (CNCs) in their anionic forms (sulfated and carboxylated) were examined as nanoadsorbents for the effective removal of cationic toxic AO. Both sulfated and carboxylated CNCs were characterized by FTIR, DLS, zeta potential, AFM and XRD techniques. The impact of both surface functionalities (half-ester sulfate and carboxylate) of CNCs were studied in relation to the adsorption of AO. The batch adsorption experiments were performed at 0 and 25°C at different contact time and the highest removal percentage (82 %) and adsorption capacity (20mgg-1) were obtained for the sulfated CNCs for an equilibrium contact time of 30min. The kinetic data was fitted to the pseudo-second-order adsorption model, with the highest rate constant (0.55gmg-1.min-1) related to the sulfated CNCs for the adsorption at 0°C. The calculated thermodynamics parameters indicated that AO adsorption on both CNC samples was a spontaneous exothermic process with a decrease in the entropy of the system for the sulfated CNCs and an increase in entropy for the carboxylated CNCs. Fitting equilibrium data to four different types of isotherms (Henry, Freundlich, Langmuir and Temkin) showed that Freundlich isotherm was the most suitable to describe the adsorption behavior of AO at either 0 or 25°C. Overall, this study demonstrated the potential application of sustainable and biodegradable wood-based CNCs as green bioadsorbents for the adsorption of toxic cationic AO dye
\u27Pouring everything that you are\u27: Musicians\u27 experiences of optimal performances
No full text© Cambridge University Press 2020. The purpose of this study was to document the lived experiences of flow during an optimal music performance. Fifteen undergraduate musicians (Mage = 19, 53% male) participated in in-depth, semi-structured interviews, where they were asked to describe an optimal performance experience. Results from an inductive qualitative analysis revealed three main themes: environmental context, emotional connectedness and interpersonal relationships, which synthesised the optimal performance experience. The results also suggest that flow among musicians appears to be a common emotional state and similar to that conceptualised in sport. The ways a musician experiences flow are important, as these can help music educators gain a better understanding of the conceptualisation of flow within music performance. However, given the nuanced differences in the sociocultural environment of a flow experience typical in a sport or music performance, additional research into the divergences of domains may be warranted
Are Consumers Put off by Retargeted Ads on Social Media? Evidence for Perceptions of Marketing Surveillance and Decreased Ad Effectiveness
No full text© 2020, © 2020 Broadcast Education Association. Consumers have described retargeted ads as “creepy,” possibly because these ads cue consumers that marketers are collecting personal data. Participants (N = 280) were either exposed to an ad that was targeted to past online behaviors or a general product ad. Behavioral targeting had a positive direct effect on purchase intent, but it also set off a negative indirect effect. Those exposed to behavioral targeting experienced increased perceived marketing surveillance, which led to increased threat, increased psychological reactance, negative attitudes toward the ad, and negative purchase intention. The indirect cost of perceived marketing surveillance on purchase intent was 4.5 percent
Integrating Health Coaching With a Medical Fitness Program to Treat Chronic Health Conditions
No full text© 2017 The Author(s). Medical fitness and health/wellness coaching (HWC) are emerging health care trends but potential synergistic effects are yet to be studied. Purpose. To determine the impact of integrating HWC within a community-based medical fitness program for patients with chronic health conditions. Methods. A before and after clinical trial, examining 3 frequency levels of coaching sessions, with Journey-to-Wellness (J2W) participants (N = 1306) who were predominately female (76%), aged 12 to 87 years (mean ± SD = 53.54 ± 14.34 years), and referred by their health care provider. Over 3 months, J2W emphasized HWC, exercise, nutrition counseling, and group/interactive events. HWC averaged 4.4 ± 2.5 sessions and was analyzed at 3 levels (0-3; 4-6; 6+ sessions). Pre-post measures were Patient Health Questionnaire (PHQ-9), Positivity, General Anxiety Disorder (GAD-7), Dartmouth Quality of Life (QoL), Lifestyle Nutrition Behavior (LNB), Pain, exercise minutes, weight, waist circumference, and systolic/diastolic blood pressures. Results. J2W intervention significantly (P \u3c.01) improved all outcomes. Between 20% and 43% improvements were observed for PHQ-9, GAD-7, QoL while LNB improved 7.5%, and biometrics between 1% and 2.2%. Greater frequency of HWC enhanced J2W effect for PHQ-9 and QoL with weight and GAD approaching significance. Conclusion. J2W programming produced measurable improvement in health metrics, with greater HWC frequency adding to these beneficial effects, providing a powerful community-based health intervention
Using marketing for good: An experiential project on cause-related marketing in a principles course
No full text© 2020 Taylor & Francis Group, LLC. Cause-Related Marketing (CRM), defined as profit motivated giving, is an effective strategy that can be used to demonstrate to students the “good side” of marketing. This paper outlines an experiential project that allowed students to gain a better understanding of marketing principles while also gaining an appreciation for corporate citizenship. Students were able to generate $11,796.11 in total profit, and collaborate with 34 unique local, national, and international nonprofits. Qualitative data indicated that students gained a deeper understanding and appreciation of marketing, market research, and marketing as a tool for CRM
Role of brand attachment in customers’ evaluation of service failure
No full text© 2020, Emerald Publishing Limited. Purpose: This paper aims to examine the role of brand attachment as a relevant construct in customers’ evaluation after they face a service failure which impacts future consumer behaviors. It mainly answers the research question: does brand attachment cushion or amplify the effect of service failure on customers’ negative emotions? Design/methodology/approach: A 2 × 2 × 2 experimental design was conducted. Data analysis was performed with ANOVA and moderated mediation. Findings: Customer’s feelings toward a brand (brand attachment) that existed before a service failure occurred can regulate customer’s negative emotions especially when consumer attribute service failure to a controllable cause. This process minimizes the effect of service failure in customer’s satisfaction and consequently increase customer behaviors like word of mouth and loyalty intentions. Research limitations/implications: Adding perceived intentionality as a service failure’s attribution could provide another layer of explanation of customer behavior. Also, an expanded study using a sector characterized by higher cost of change and permanent consumption could provide result’s generalizability. Practical implications: Brand attachment should be included in the customer service strategy. In a service failure situation, brand attachment becomes part of the “service customer policy” helping customers to regulate their negative emotions. Originality/value: This study fills the knowledge gap regarding the role of customers’ positive emotions toward brands when a service failure occurs. The current study extends branding literature by differentiating brand attachment role from coping tactics
