L’approccio more-than-cyberplace nei casi di attivismo per l’ambiente. La storia della riserva naturale di Glen of the Downs (Irlanda)
Authors: Albanese Valentina 
Published: January 2024

Abstract The More-than-Cyberplace Approach for Environmental Activism: Insights from the Glen of the Downs Nature Reserve (Ireland) Eco-warriors are a group of activists who have been fighting for many years to protect ecosystems threatened by human action. This paper aims to examine ex-post the case of the oldest natural reserve in Ireland, Glen of the Downs, which provided a context in which an innovative example of activism in Europe has been developed, especially since 1997, marking a change of direction from environmental blocks to safeguard biodiversity and the ecosystems. The collection of secondary data offered by documents and videos of that period offers a numeral of arguments to reflect the need for a multi-disciplinary and multi-scalar interpretative framework. Therefore, the conceptual category of more-thancyberplace is suggested for the interpretation of the case study.

Published: January 2024

Background: Sodium-glucose cotransporter-2 (SGLT2) inhibitors have recently drawn attention as a viable therapy for acute heart failure (AHF). Despite this, a comprehensive synthesis of current research has not been undertaken.
Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this systematic review evaluated eight studies involving 3,352 participants. The scope encompassed research from the last twenty years, focusing on the effectiveness of SGLT2 inhibitors in AHF management. Detailed considerations regarding the temporal context and heterogeneity were incorporated into the methodology.
Results: The utilization of SGLT2 inhibitors yielded compelling results in improving cardiovascular outcomes, showcasing a substantial 58.2% reduction in major adverse cardiovascular events (MACE) and a noteworthy 15% decrease in NT-proBNP levels. Empagliflozin therapy, specifically, exhibited enhanced clinical efficacy, as indicated by a 48% improvement in the Kansas City Cardiomyopathy Questionnaire Total Symptom Score. Furthermore, a detailed analysis revealed that markers of acute kidney injury witnessed a significant reduction after the administration of empagliflozin. This reduction reached statistical significance after 3 days of treatment (P=0.02) and persisted through the 7-day assessment (P=0.003). This comprehensive exploration of the results provides a more nuanced understanding of the multifaceted benefits associated with SGLT2 inhibitors, particularly empagliflozin, in the management of acute heart failure.
Conclusion: The current body of research strongly supports the application of SGLT2 inhibitors in managing AHF, emphasizing considerable improvements in clinical outcomes. Despite these positive findings, the abstract acknowledges the need for further research to determine the optimal timing, dosage, long-term safety of these inhibitors, and their effectiveness across diverse patient populations.

Published: January 2024

Background: The escalating prevalence of stress and anxiety disorders has emerged as a pronounced public health concern, exerting a profound impact on the global well-being of individuals. Despite its increasing recognition, empirical investigations into the precise application of Reiki therapy for stress and anxiety disorders remain scant.
Primary Study Objective: This pilot study aims to fill this critical void by delving into the potential benefits of Reiki therapy as a complementary intervention for the treatment and management of stress and anxiety.
Methods: In this observational study, 31 volunteers self-reporting stress, anxiety, or psychological disorders were enrolled according to the inclusion and exclusion criteria. Health-related quality of life (HRQoL) was assessed using the 36-Item Short Form Health Survey (SF-36) Questionnaire for anxiety and depression. Pre- and post-treatment HRQoL scores were meticulously compared, and the significance of the disparities in these scores was meticulously computed.
Setting: The study was conducted at Patanjali Yogpeeth in Haridwar.
Results: Analysis was restricted to volunteers who completed the 3-day Reiki sessions. Strikingly, statistically significant enhancements were discerned across all outcome measures, encompassing positive affect, negative affect, pain, drowsiness, tiredness, nausea, appetite, shortness of breath, anxiety, depression, and overall well-being (P<0.0001).
Conclusion: The constancy and extensive scope of these improvements suggest that Reiki therapy may not only address specific symptoms but also contribute significantly to a predominant escalation of mental and physical health.
Effects of menstrual cycle phase on reporting levels of aggression using the buss and perry aggression questionnaire
Authors: Ritter Dominik 
Published: October 2003

AbstractThe Aggression Questionnaire [Buss and Perry, 1992, Journal of Personality and Aggression, vol. 63, pp. 452–459] was administered to women at menses and during the midluteal phase of their menstrual cycles to assess changes in reporting aggressive behavior as a function of menstrual phase. Men served as a control group, and also received the questionnaire twice, once at session I and once at session II. Women at menses reported a significantly higher level of physically aggressive behavior than during the midluteal phase. A similar but non‐significant trend was found for reporting verbal aggression. There were no changes in reporting of anger or hostility across the menstrual cycle. This produced a significant sex‐difference on reporting physical aggression between men and women at the midluteal phase but not at menses. Aggr. Behav. 29:531–538, 2003. © 2003 Wiley‐Liss, Inc.
Perceptions and experience of workplace bullying in five different working populations
Authors: Jennifer Dawn , Cowie Helen , Ananiadou Katerina 
Published: October 2003

AbstractWhilst aggression in the workplace has been systematically studied in recent years, research into workplace bullying per se still remains quite limited. In this article, we report the findings from an investigation into employees' perceptions of social and organizational work conditions and experiences of bullying at work. Six‐hundred‐seventy‐seven employees from five different working populations (managers, teachers, technicians, call centre operators, and engineers) completed the Workplace Relationships Questionnaire (WRQ). This paper presents the results of the analysis, linking the experiences of bullying and perceptions of social and organizational work conditions. The present findings predictably identify victims and non‐bullied participants, and also indicate the existence of a new category of employee affected by the problem of bullying; bullied/non‐victims. Bullied/non‐victims may provide crucial insights into the ways that company practices and policies impact negatively on the whole workforce. Aggr. Behav. 29:489–496, 2003. © 2003 Wiley‐Liss, Inc.
Influence of executive functioning difficulties on verbal aggression in adolescents: Moderating effects of winning and losing and increasing and decreasing levels of provocation
Authors: Santor Darcy A. , Ingram Adrienne , Kusumakar Vivek 
Published: October 2003

AbstractWe examined the extent to which executive functioning difficulties were related to verbal aggression under conditions of gradually increasing or decreasing provocation over both winning and losing trials. Sixty adolescent boys and girls completed a modified Taylor aggression paradigm in which verbally offensive remarks were sent and received. Results showed (a) that during increasing levels of provocation, verbal aggression increased on both winning and losing trials, (b) that verbal aggression decreased during decreasing levels of provocation but only on losing trials, and (c) that difficulties on two measures of executive functioning were related to verbal aggression, but only in the context of increasing verbal provocation. Individuals with executive functioning difficulties responded with more verbal aggression than did individuals with less severe executive functioning difficulties. Results have implications for the manner in which provocation is studied and for understanding the conditions in which executive functioning difficulties contribute to verbal aggression. Aggr.

Binding Affinities of Host–Guest, Protein–Ligand, and Protein–Transition‐State Complexes
Authors: Houk K. N. , Leach Andrew G. , Kim Susanna P. , Zhang Xiyun 
Published: October 2003

AbstractThe affinities of hosts—ranging from small synthetic cavitands to large proteins—for organic molecules are well documented. The average association constants for the binding of organic molecules by cyclodextrins, synthetic hosts, and albumins in water, as well as of catalytic antibodies or enzymes for substrates are 103.5±2.5 M−1. Binding affinities are elevated to 108±2 M−1 for the complexation of transition states and biological antigens by antibodies or inhibitors by enzymes, and to 1016±4 M−1 for transition states with enzymes. The origins of the distributions of association constants observed for the broad range of host–guest systems are explored in this Review, and typical approaches to compute and analyze host–guest binding in solution are discussed. In many classes of complexes a rough correlation is found between the binding affinity and the surface area that is buried upon complexation. Enzymes transcend this effect and achieve transition‐state binding much greater than is expected from the surface areas.
Electrochemical and Photochemical Control of Host–Guest Complexation at Surfaces
Authors: Cooke Graeme 
Published: October 2003

AbstractThe application of electrochemistry or photochemistry to modulate supramolecular interactions between host–guest systems in solution is a burgeoning field. In particular, the speed and reversibility associated with electrochemically or photochemically actuated supramolecular interactions has allowed the creation and modulation of novel solution‐based devices. In recent years, great advances have been made in transferring these systems from the solution to the solid state, to facilitate the development of molecular‐electronics components that can operate in unison under the influence of an externally applied stimulus. These studies pave the way for the creation of responsive surfaces with advanced materials and nanotechnology applications.

Published: October 2003

AbstractThe preparation of new cellulose fiber reinforced thermoplastics is described, and the mechanical properties and water absorption of these materials are measured.In order to improve the compatibility between cellulosic and plastic materials, different amounts of coupling agents, such as organotitanate compounds, maleic anhydride copolymers and their combinations, are studied. As a filler, pine fiber, rose, carnation or coffee husk is used. Furthermore, the influence of the composition of the composites and the particle size of the filler on the material properties of the thermoplastics are investigated. The surface of the fractured samples is analyzed using scanning electron microscopy (SEM). © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 90: 3466–3472, 2003
Spinning fibers from poly(ethylene terephthalate) bottle‐grade waste
Authors: Gurudatt K. , De P. , Rakshit A. K. , Bardhan M. K. 
Published: October 2003

AbstractPoly(ethylene terephthalate) bottle‐grade (BG) waste was converted into spinnable chips and spun on a laboratory‐scale melt‐spinning apparatus into filaments. Virgin fiber‐grade (FG) polyester chips were blended with BG waste during melt spinning so that the influence of blending on the fiber properties could be studied. Subsequently, the scaling‐up of the process was carried out in a polyester recycling plant so that staple fibers could be obtained. In this part of the study, the spinning of blends of BG waste and FG waste was carried out. The BG waste was found to be superior feed stock for melt processing. Fibers with unique properties were obtained from the BG waste. Staple fibers obtained by the blending of FG and BG waste showed properties different from those of fibers spun from BG waste alone. This study also showed that using blends of BG and FG waste could improve the melt processing and staple‐fiber properties. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 90: 3536–3545, 2003
Properties of poly(lactic acid) blends with various starches as affected by physical aging
Authors: Wang Hua , Sun Xiuzhi , Seib Paul 
Published: October 2003

AbstractPoly(lactic acid) (PLA) and starch are both biodegradable and renewable polymers derived from agricultural feedstock. A previous study showed that a small amount (0.5%) of methylenediphenyl diisocyanate (MDI) could enhance the mechanical properties of starch and PLA blends by improving the interfacial interaction. In this study, blends of PLA (1/1, w/w) and starch with or without MDI were evaluated for thermal and mechanical properties as well as morphology, as affected by physical aging when stored up to 12 months at 25 °C and 50% relative humidity. The blends were prepared by thermally blending PLA with wheat starch, corn starch, and/or high amylose corn starch, with or without MDI. All samples exhibited phenomena of physical aging. The samples with MDI aged more slowly, showing a slower reduction rate of excess enthalpy relaxation, than those without MDI. The mechanical properties decreased slowly as aging proceeded. Microstructure showed a reduced interaction between starch and PLA around the interface with aging. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 90: 3683–3689, 2003
Effect of ultrasound on extrusion of polypropylene/ethylene–propylene–diene terpolymer blend: Processing and mechanical properties
Authors: Chen Yingzi , Cao Yurong , Li Huilin 
Published: October 2003

AbstractThe effects of ultrasonic irradiation on extrusion processing and mechanical properties of polypropylene (PP)/ethylene–propylene–diene terpolymer (EPDM) blends are examined. Results show that appropriate irradiation intensity can prominently decrease die pressure and apparent viscosity of the melt, increase output, as well as increase toughness of PP/EPDM blends without harming rigidity. In case the blends are extruded with ultrasonic irradiation twice, the impact strength of the blend rises sharply at 50–100 W ultrasonic intensity, and amounts to more than 900 J/m, 1.5 times as high as that of blend without ultrasonic irradiation. Scanning electron microscopy observation shows that with ultrasonic irradiation, morphology of uniform dispersed EPDM phase and good adhesion between EPDM and PP matrix was formed in PP/EPDM blend. © 2003 Wiley Periodicals, Inc.

XPS study of aged polyaniline films
Authors: Jousseaume V. , Morsli M. , Bonnet A. 
Published: October 2003

AbstractIn this article, a study of the aging of conducting Polyaniline–Polystyrene blends using X‐ray photoelectron spectroscopy (XPS) and UV‐visible‐near IR analysis is presented. The physicochemical results are compared to those obtained by electrical measurements. XPS results confirm the existence of an oxidation process also deduced by the electrical conductivity studies. The N1s and S2p core level spectra decomposition allows to show that a deprotonation process and cyclization of tertiary amine occur during aging. The absorption spectrum shows a decrease of delocalized charges and the apparition of localized polarons after a long aging time. All these mechanisms are responsible of the electrical conductivity decrease observed during aging at elevated temperature. The results are presented for films of PANI–CSA–PSt blends, but the conclusions can be extended to pure conducting PANI–CSA films. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 90: 3730–3736, 2003
