Livestock Antibiotic Effects on Nitrification, Denitrification, and Microbial Community Composition in Soils  [PDF]
Sagarika Banerjee, Elisa DAngelo
Open Journal of Soil Science (OJSS) , 2013, DOI: 10.4236/ojss.2013.35024

The broiler (Gallus gallus domesticus) industry in the United States and several other countries routinely includes subtherapeutic levels of antibiotics such as roxarsone, virginiamycin, and bacitracin in the feed to improve bird growth yields. Large fractions of the antibiotics fed to the birds are excreted in manure (litter), which is often applied to soils to improve fertility. Some concerns with this practice are antibiotic-induced alterations in microbially-mediated nutrient cycling, which could influence plant productivity and environmental quality. To investigate this possibility, a series of lab experiments were conducted to determine the effects of increasing levels of the three livestock antibiotics on nitrification, denitrification, and microbial community composition (fatty acid methyl ester profiles) of soils collected along a catena. Roxarsone and virginiamycin significantly influenced microbial community composition and inhibited nitrification in the soils, but only at levels that were several-fold higher than expected in poultry litter-applied soils. Bacitracin did not affect microbial growth, microbial community composition, or nitrification at any concentration tested (up to 500 mg·kg-1). None of the antibiotics influenced denitrification at environmentally-relevant concentrations. Amounts of antibiotics in soil solution were greatly reduced by sorption, which followed Freundlich models in the concentration range of 1 - 500 mg·L-1. Results from this study indicated that addition of roxarsone, virginiamycin, or bacitracin to these soils at environmentally-relevant concentrations would not likely impact microbial community composition, nitrification or denitrification due to intrinsic resistance/insensitivity of microorganisms to these antibiotics and reductions in the bioavailable amounts due to sorption by soil surfaces.

The Virtuous Circle of Corporate Social Performance and Corporate Social Disclosure  [PDF]
Francesco Gangi, Eugenio DAngelo
Modern Economy (ME) , 2016, DOI: 10.4236/me.2016.712129
Abstract: Previous literature in the field of corporate social responsibility investigates whether corporate social performance can be seen as a determinant of corporate social disclosure or, conversely, if corporate social disclosure is a determinant of corporate social performance. The aim of this paper is to join these two streams of research in a unique theoretical model, which can demonstrate that there is a mutual interaction between performance and disclosure. This can result, in the long run, in a virtuous circle where higher social performance generates future higher social disclosure and this determines higher future social performance and so on. An analytical model has been adopted to demonstrate the research hypothesis. Gathering data from the portfolios of the European Socially responsible funds (SRFs) listed on the Morningstar platform in 2010, the study analyzed 160 social reports published by 80 companies during 2008 and 2009. Findings, by demonstrating the non-one-way relationship between social performance and social disclosure, confirm the existence of a mutual influence between the results gained in different CSR areas and the capability to control and communicate such performance. In this way, the paper provides not only theoretical insights, but also practical implications for managers that are required to put in place responsive and effective initiatives towards the increasing pressure exerted by the internal and external environments in which they operate.
Protective Factors for the Well-Being in Caregivers of Patients with Alzheimer’s: The Role of Relational Quality  [PDF]
Caterina Gozzoli, Antonino Giorgi, Chiara DAngelo
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.46A1009

The work highlights one of the direct stakeholders of RSA organization, the caregivers of patients with Alzheimer. It studies if and in which measure the caregivers’ level of health are strongly influenced by their perceived Relational Quality of the retirement homes in which their loved ones are hospitalized. Participants were 111 caregivers of patients with a diagnosis of dementia and recovered in RSA since at least 6 months. The study measures if the relational quality perceived by caregivers has a positive and direct influence on two mood states of caregivers: depression-dejection, anger-hostility. It also investigates if the protective function of relational quality remains significant also in presence of moderator variable such as social support and burden. The analysis confirms that increasing perceived relational quality corresponds to a decreased perception of caregivers’ discomfort humoral. The social support factor does not act as moderator, but it is confirmed the moderator role of burden. The research work provided some important empirical about the important role of caregivers retirement homes. They represent an emotional and relational link that connects the guest on one hand with the familiar net and on the other hand with the service operators. Therefore caregiver is a central resource, who needs protection and valorisation.

Is the Lending Decision-Making Process Affected by Behavioral Biases?
—Evidence from Southern Italy

Eugenio DAngelo, Mario Mustilli, Rossana Piccolo
Modern Economy (ME) , 2018, DOI: 10.4236/me.2018.91010
Abstract: The objective of this article was to verify whether, in the decision-making process concerning bank loans issuance, managers have been influenced or not by how they perceive some personal characteristics of the applicant, even if these characteristics have nothing to do with the financial aspects typically analyzed to determine creditworthiness. In particular, we analyzed the impact of gender, age, beauty, race and education of the borrower on the probability to be funded. The study was conducted submitting face-to-face questionnaires to 212 officers working in the credit chain of 25 banks and data have been analyzed using the logistic regression model. The chosen setting was the south of Italy and in particular of the Campania region. The results show that there has been some influence of bias regarding gender, age and beauty, while no significant relationship has been found with reference to the racial discrimination or to the cultural level of the applicant. These results, which confirm the evidence already found in other settings by previous empirical analyses, would lead to highlight that there is an adverse selection mechanism in the provision of banks' credit capital.
Cross-Country Differences in How Behavioral Biases Affect Decision-Making in the Bank Industry: Evidence from Italy and Serbia  [PDF]
Mario Mustilli, Rossana Piccolo, Eugenio DAngelo
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.82016
Abstract: Since non-performing loans, despite the implementation of the Basel accords, which should have improved creditworthiness estimation, are strongly affecting European banks’ liquidity and stability, there could be a behavioral bias behind banks misallocation of capital. The purpose of this study is to investigate whether behavioral biases affect credit allocation in different ways in different countries. Particularly, we investigated how certain characteristics of the applicants, such as race, age, gender and education, affect bank officers’ decision-making process. The study was conducted submitting face-to-face questionnaires to 299 officers, 212 in Italy and 87 in Serbia, working in the credit chain. Running a Mann-Whitney U test on the mentioned two independent samples, result show that Italian officers are more influenced by behavioral biases than their Serbian colleagues when they have to decide whether or not to approve a loan application.
A modernidade pelo olhar de Walter Benjamin
D'Angelo, Martha;
Estudos Avan?ados , 2006, DOI: 10.1590/S0103-40142006000100016
Abstract: this article's aim is to sketch a profile of modernity using as reference the essays "paris, capital of the 19th century" and "paris of the second empire in baudelaire", by walter benjamin. it attempts to fathom the relationships between the french revolutionary process, the commercialization of society and art, and the poetic work of baudelaire.
Analysis by Fourier transform infrared spectroscopy of Johnstonia (Corystospermales, Corystospermaceae) cuticles and compressions from the Triassic of Cacheuta, Mendoza, Argentina
D`angelo,José Alejandro;
Ameghiniana , 2006,
Abstract: spectroscopic information (functional groups and semi-quantitative data) of corystosperm cuticles and compressions from the triassic of cacheuta, mendoza, argentina, is reported for the first time. fossil leaves of johnstonia spp. (corystospermales, corystospermaceae) were analyzed by fourier transform infrared spectroscopy (ft-ir) in an attempt to identify spectroscopic patterns that would characterize these taxa. infrared spectra obtained from cuticles and compressions of johnstonia spp. showed a relatively rich aliphatic structure as well as hydroxyl, carbonyl and some other oxygen-containing functional groups. semi-quantitative data derived from ft-ir spectra were statistically analyzed using one-way analysis of variance test (anova). in the three taxa studied herein, one-way anova revealed significant differences between cuticles and their corresponding compressions regarding the ch2/ch3 ratio (p < 0.05). considering the ft-ir-derived ratios ch2/ch3, al/ox, ox1/ox2 and c-h/c=o, there were not significant differences (p > 0.05) between abaxial and adaxial surfaces in the cuticular samples of johnstonia coriacea var. coriacea (johnston) walkom here studied. infrared-derived ratios here considered (ch2/ch3, al/ox and ar/al) in compression samples did not differ significantly from one taxon to the other (p > 0.05). however, cuticular specimens of johnstonia spp. showed statistical differences (p < 0.05) among the taxa studied, considering ch2/ch3, ox1/ox2 and c-h/c=o ratios. although these results are suggestive of the likely application of ft-ir technique to the chemotaxonomic study of the corystospermaceae, more data are needed before obtaining definitive conclusions.
La teoría del dominio del hecho en la legislación penal colombiana
Scheller D'angelo,André;
Revista de Derecho , 2011,
Abstract: the argument against the involvement of people in criminal law focuses on establishing if someone who participates in the commission of a crime is the author of it, or alternatively, if it is possible to distinguish between subjects who concur in their perpetration. criminal codes currently provide various forms of intervention in the crime however, the term referred to anyone who is involved in producing the result is the same author (unitary copyright), was the first link in the chain which led to many discussions following the dogmatic issue. according to contemporary dogma, under authoring, the determination of who the perpetrator of a criminal act is, it is possible to distinguish two ways: a) cover with the concept of authoring to all those involved in the act; or, b) establishing differentiations among people who attend.
La experiencia de la corporalidad en imágenes. Percepción del mundo, producción de sentidos y subjetividad
Tabula Rasa , 2010,
Abstract: this paper views body as a receptor and producer of cultural meanings from the anthropological and sociological perspectives. it intends to reflect on the effect of media images on corporeality in contemporary societies. the double dimension is moved, as far as we are concerned here, to the body represented and the body perceiving its own image, mirrored on other bodies. as per the extent of this work, i will consider the ways how subjects' relationship to corporeality is settled from and through body image: a) the body as the location of the world's perceptive experience; b) the body as the place where meanings other bodies' images are produced; and c) the individual face to his/her own body's images.
A ética no marketing
D'Angelo, André Cauduro;
Revista de Administra??o Contemporanea , 2003, DOI: 10.1590/S1415-65552003000400004
Abstract: marketing is probably the organizational function with more visibility and it is constantly being put under discussion from the ethics point of view. marketing practices have been historically criticized, making the analysis of its ethical aspects an important and necessary topic in the academic environment. there are basically two categories of questions concerning marketing ethics: the first one is related to the capitalist system as a whole and discusses the supposed materialist stimulus developed by marketing; the second one has a more practical emphasis and is focused on marketing activities such as pricing, advertising and sales. both of these categories are constituted of many points of views and there is no consensus about them; ethics is a complex and subjective concept and tends to be interpreted according to the circumstances and personal perceptions. as a result, marketing and business players move in an amoral zone, letting to the market and the society the task to judge them.
