Examination of the influence of behavioral, normative and control beliefs on the adherence to a prescribed renal diet among elderly populations with chronic to end-stage renal disease

The 1999-2004 prevalence of chronic kidney disease in adults 20 year or older (15.5 million) is an estimated 7.69%. The risk of developing CKD is exacerbated by diabetes, hypertension and/or a family history of kidney disease. African Americans, Hispanics, Pacific Islanders, Native Americans, and the elderly are more susceptible to higher incidence of CKD. The challenges of aging coupled with co-morbidities such as kidney disease raises the potential for malnutrition among elderly (for the purpose of this study 55 years or older) populations. Lack of adherence to prescribed nutrition guidelines specific to renal failure jeopardizes body homeostasis and increases the likelihood of future morbidity and resultant mortality. The relationship and synergy that exists between diet and disease is evident. Clinical experience with renal patients has indicated the importance of adherence to diet therapy specific to kidney disease. Extension investigation of diet adherence among endstage renal disease patients revealed a sizeable dearth in the current literature. This thesis study was undertaken to help reduce that void. The study design is qualitative and descriptive. Support, cooperation, and collaboration were provided by the University of Texas Nephrology Department, University of Texas Physicians, and DaVita Dialysis Centers. Approximately 105 male and female chronic to end-stage kidney disease patients were approached to participate in elicitation interviews in dialysis treatment facilities regarding their present diet beliefs and practices. Eighty-five were recruited and agreed to participate. Inclusion criteria required individuals to be between 35-90 years of age; capable of completing a 5-10 minute interview; and English speaking. Each kidney patient was asked seven (7) non-leading questions developed from the constructs of the Theory of Planned Behavior. The study presents a descriptive comparison of behavioral, normative, and control beliefs that influence adherence to renal diets by age, race, and gender. The study successfully concluded that behavioral, normative, and control beliefs of chronic to end-stage renal patients promoted execution and adherence to prescribed nutrition. This study provides valuable information for dietitians, technicians, nurses, and physicians to assess patient compliance toward prescribed nutrition and the means to support or improve that performance. ^

Influence of gamma radiation onto polymeric matrix with papain

Papain is a proteolytic enzyme that has been widely used as debridement agent for scars and wound healing treatment. However, papain presents low stability, which limits its use to extemporaneous or short shelf-life formulations. The purpose of this study was to entrap papain into a polymeric matrix in order to obtain a drug delivery system that could be used as medical device. Since these systems must be sterile, gamma radiation is an interesting option and presents advantages in relation to conventional agents: no radioactive residues are formed: the product can be sterilized inside the final packaging and has an excellent reliability. The normative reference for the establishment of the sterilizing dose determines 25 kGy as the inactivation dose for viable microorganisms. A silicone dispersion was selected to prepare membranes containing 2% (w/w) papain. Irradiated and non-irradiated membranes were simultaneously assessed in order to verify whether gamma radiation interferes with the drug-releasing profile. Results showed that irradiation does not affect significantly papain release and its activity. Therefore papain shows radioresistance in the irradiation conditions applied. In conclusion, gamma radiation can be easily used as sterilizing agent without affecting the papain release profile and its activity onto the biocompatible device is studied. (C) 2009 Elsevier Ltd.

Transient evoked otoacoustic emissions in 6-year-old school children: a normative study

Great potential has recently been demonstrated for the application of transient evoked otoacoustic emissions (TEOAEs) in screening the hearing of school-aged children. The present study aimed to describe the range of TEOAE values obtained from a large cohort of 6-year-old children in school settings. Results indicated significant sex and ear asymmetry effects on signal-to-noise ratio, response, whole wave reproducibility, band reproducibility and noise levels. A prior history of ear infections was also shown to influence response level, whole wave reproducibility and band reproducibility. The sex, ear and history specific normative data tables derived may contribute to future improvements in the accuracy of hearing screening for 6-year-old school children.

Changes in the influence of board characterisitcs on corporate results due to the recent global financial crisis

The main purpose of this study is to analyse the changes caused by the global financial crisis on the influence of board characteristics on corporate results, in terms of corporate performance, corporate risk-taking, and earnings management. Sample comprises S&P 500 listed firms during 2002-2008. This study reveals that the environmental conditions call for different behaviour from directors to fulfil their responsibilities and suggests changes in normative and voluntary guidelines for improving good practices in the boardroom.

Liberties and constraints of the normative approach to evaluation and decision in forensic science: a discussion towards overcoming some common misconceptions

At a time when disciplined inference and decision making under uncertainty represent common aims to participants in legal proceedings, the scientific community is remarkably heterogenous in its attitudes as to how these goals ought to be achieved. Probability and decision theory exert a considerable influence, and we think by all reason rightly do so, but they go against a mainstream of thinking that does not embrace-or is not aware of-the 'normative' character of this body of theory. It is normative, in the sense understood in this article, in that it prescribes particular properties, typically (logical) coherence, to which reasoning and decision making ought to conform. Disregarding these properties can result in diverging views which are occasionally used as an argument against the theory, or as a pretext for not following it. Typical examples are objections according to which people, both in everyday life but also individuals involved at various levels in the judicial process, find the theory difficult to understand and to apply. A further objection is that the theory does not reflect how people actually behave. This article aims to point out in what sense these examples misinterpret the analytical framework in its normative perspective. Through examples borrowed mostly from forensic science contexts, it is argued that so-called intuitive scientific attitudes are particularly liable to such misconceptions. These attitudes are contrasted with a statement of the actual liberties and constraints of probability and decision theory and the view according to which this theory is normative.

L'influence des marqueurs identitaires du juge dans les décisions relatives à la garde des enfants dans un contexte post-rupture

L’« intérêt de l’enfant » est un concept fondamental en droit de la famille puisqu’il constitue le critère déterminant dans toute décision qui concerne l’enfant. Le Code civil du Québec énonce, au second alinéa de l’article 33, les facteurs qui doivent servir à le déterminer, soit « les besoins moraux, intellectuels, affectifs et physiques de l’enfant, son âge, sa santé, son caractère, son milieu familial et les autres aspects de sa situation ». Les auteurs qui s’y sont intéressés l’ont abordé sous différents angles. Certains se sont intéressés à ses origines et à son évolution. D’autres en ont proposé leur propre définition. En ce qui nous concerne, nous avons choisi d’explorer ledit concept en nous intéressant aux diverses interprétations qu’il reçoit de la part des tribunaux dans les décisions relatives à la garde des enfants dans un contexte post-rupture, et ce, à la lumière du genre et de l’âge du décideur. Le concept d’intérêt de l’enfant étant hautement indéterminé, son interprétation est laissée à l’appréciation du juge qui en précisera le contenu en référence à la loi et aux faits particuliers de chaque cas d’espèce. Or, dans les situations où, une fois considéré le contexte factuel et normatif, le juge se retrouve face à une situation « neutre », c’est-à-dire où la garde exclusive et la garde partagée sont tout aussi envisageables, peut-on prétendre que son l’inclinaison vers l’une ou l’autre de ces modalités de garde est influencée par des facteurs autres que le droit et les faits mis en preuve ? Telle est la question au cœur de notre étude. Reposant sur des théories reconnues et bien établies affirmant l’importance de tenir compte du contexte social et de l’expérience individuelle du décideur dans la démarche interprétative que le droit sous-tend, l’hypothèse que nous soumettons est qu’au-delà des faits mis en preuve et du droit, des éléments indissociables au processus d’interprétation, à savoir les valeurs, les idéologies et les traits caractéristiques dominants que sous-tendent le genre et la génération du décideur, influent sur la teneur des jugements qu’il prononce. Sans admettre que ces éléments suffisent, à eux seuls, pour expliquer le produit judiciaire, nous sommes d’avis qu’on ne peut qualifier d’improbable l’incidence qu’ils exercent sur celui-ci. Nous intéressant au processus cognitif qui préside à la réflexion des décideurs, notre thèse vise à cerner, à travers une analyse interdisciplinaire, les facteurs humains et les forces sociales qui structurent les expériences et qui sont susceptibles d’avoir un impact sur les décisions judiciaires. L’objectif de notre étude n’est pas d’établir un lien de causalité entre le genre et l’âge du juge et les décisions qu’il rend, mais plutôt de vérifier si des corrélations peuvent être établies entre ces paramètres. Désirant aller au-delà des perceptions traditionnelles véhiculées par la doctrine classique, nos travaux se veulent davantage une contribution au développement d’une conception non formaliste du droit plutôt qu’une démonstration que le profil identitaire des décideurs conditionne systématiquement et invariablement leurs décisions. Une étude de ce genre comporte certes des difficultés en ce qu’elle confronte le juriste à des concepts et des théories qui appartiennent à d’autres champs disciplinaires et qui, partant, ne lui sont pas familiers. La compréhension plus fine du processus interprétatif et des décisions qui en résultent en justifie cependant le bien-fondé.

The influence of a decision support tool on real estate valuations

An appraisal task involves the rendering of market value, an unobservable and hypothetical construct. Direct feedback against this objective is typically not possible, so alternative feedback such as confirmation of previous appraised values may be employed. This may alter the appraiser’s perception of the valuation objective leading to divergence from the appraisal normative model. The real estate literature suggests appraisers have been susceptible to the influence of previous appraised values, often resulting in biased valuations. This research focuses on the efficacy of a decision support tool in eliminating or subduing this bias in the appraisal process.

Normative MR Cervical Spinal Canal Dimensions

Purpose To provide normal values of the cervical spinal canal and spinal cord dimensions in several planes with respect to spinal level, age, sex, and body height. Materials and Methods This study was approved by the institutional review board; all individuals provided signed informed consent. In a prospective multicenter study, two blinded raters independently examined cervical spine magnetic resonance (MR) images of 140 healthy volunteers who were white. The midsagittal diameters and areas of spinal canal and spinal cord, respectively, were measured at the midvertebral levels of C1, C3, and C6. A multivariate general linear model described the influence of sex, body height, age, and spinal level on the measured values. Results There were differences for sex, spinal level, interaction between sex and level, and body height, while age had significant yet limited influence. Normative ranges for the sagittal diameters and areas of spinal canal and spinal cord were defined at C1, C3, and C6 levels for men and women. In addition to a calculation of normative ranges for a specific sex, spinal level, age, and body height data, data for three different height subgroups at 45 years of age were extracted. These results show a range of the spinal canal dimensions at C1 (from 10.7 to 19.7 mm), C3 (from 9.4 to 17.2 mm), and C6 (from 9.2 to 16.8 mm) levels. Conclusion : The dimensions of the cervical spinal canal and cord in healthy individuals are associated with spinal level, sex, age, and height. © RSNA, 2013 Online supplemental material is available for this article.

Coercive, Normative, and Mimetic Influences on the Assimilation of BCM in Outsourcing Relationships

Today many business processes are based on IT systems. These systems are exposed to different threats, which may lead to failures of critical business pro-cesses. Thus, enterprises prepare themselves against threats and failures of critical IT systems by means of Business Continuity Management (BCM). The phe-nomenon of outsourcing introduces a new dimension to BCM. In an outsourcing relationship the client organization is still responsible for the continuity of its processes but does not have full control over the implemented business continuity measures. In this paper we build a research model based on institutional and assimilation theories to describe and explain how and why BCM is assimilated in outsourcing relationships. In our case studies we found evidence that primarily coercive and normative pressures influence the assimilation of BCM in outsourcing relationships and support the explanation of variation across enterprises. Mimetic pressures seem to influence the assimilation but do not explain variations.

Influence of the track quality and of the properties of the wheel rail rolling contact on vehicle dynamics

This work describes an analytical approach to determine what degree of accuracy is required in the definition of the rail vehicle models used for dynamic simulations. This way it would be possible to know in advance how the results of simulations may be altered due to the existence of errors in the creation of rolling stock models, whilst also identifying their critical parameters. This would make it possible to maximize the time available to enhance dynamic analysis and focus efforts on factors that are strictly necessary.In particular, the parameters related both to the track quality and to the rolling contact were considered in this study. With this aim, a sensitivity analysis was performed to assess their influence on the vehicle dynamic behaviour. To do this, 72 dynamic simulations were performed modifying, one at a time, the track quality, the wheel-rail friction coefficient and the equivalent conicity of both new and worn wheels. Three values were assigned to each parameter, and two wear states were considered for each type of wheel, one for new wheels and another one for reprofiled wheels.After processing the results of these simulations, it was concluded that all the parameters considered show very high influence, though the friction coefficient shows the highest influence. Therefore, it is recommended to undertake any future simulation job with measured track geometry and track irregularities, measured wheel profiles and normative values of wheel-rail friction coefficient.

The Legal Status and Influence of Decisions of International Organizations and other Bodies in the European Union. College of Europe Research Paper in Law 01/2014

Introduction. The European Union’s external action is not only defined by its influence on international developments, but also by its ability and the need to respond to those developments. While traditionally many have stressed the EU’s ‘autonomy’, over the years its ‘dependence’ on global developments has become more clear.2 International law has continued to play a key role in, not only in the EU’s external relations, but also in the Union’s own legal order.3 The purpose of this paper is not to assess the role or performance of the EU in international institutions.4 Rather it purports to reverse the picture and focus on a somewhat under-researched topic: the legal status of decisions of international organizations in the EU’s legal order.5 While parts of the status of these decisions relate to the status of international agreements and international customary law, it can be argued that decisions of international organizations and other international bodies form a distinct category. In fact, it has been observed that “this phenomenon has added a new layer of complexity to the already complex law of external relations of the European Union”.6 Emerging questions relate to the possible difference between decisions of international organizations of which the EU is a member (such as the FAO) and decisions of organizations where it is not (irrespective of existing competences in that area – such as in the ILO). Questions also relate to the hierarchical status of these decisions in the EU’s legal order and to the possibility of them being invoked in direct or indirect actions before the Court of Justice. This contribution takes a broad perspective on decisions of international organizations by including decisions taken in other international institutions which do not necessarily comply with the standard definition of international organizations,7 be it bodies set-up by multilateral conventions or informal (transnational / regulatory) bodies. Some of these bodies are relatively close to the EU (such as the Councils established by Association Agreements – see further Section 5 below); others operate at a certain distance. Limiting the analysis to formal international organizations will not do justice to the manifold relationships between the European Union and various international bodies and to the effects of the norms produced by these bodies. The term ‘international decisions’ is therefore used to refer to any normative output of international institutional arrangements.

Explaining landholders' decisions about riparian zone management: The role of behavioural, normative, and control beliefs

Water quality is a key concern in the current global environment, with the need to promote practices that help to protect water quality, such as riparian zone management, being paramount. The present study used the theory of planned behaviour as a framework for understanding how beliefs influence decisions about riparian zone management. Respondents completed a survey that assessed their behavioural, normative, and control beliefs in relation to intentions to manage riparian zones on their property. The results of the study showed that, overall, landholders with strong intentions to manage their riparian zones differed significantly in terms of their beliefs compared to landholders who had weak intentions to manage their riparian zones. Strong intentions to manage riparian zones were associated with a favourable cost-benefit analysis, greater perceptions of normative support for the practice and lower perceptions of the extent to which barriers would impede management of riparian zones. It was also evident that willingness to comply with the recommendations of salient referents, beliefs about the benefits of riparian zone management and perceptions of the extent to which barriers would impede riparian zone management were most important for determining intentions to manage riparian zones. Implications for policy and extension practice are discussed. (c) 2005 Elsevier Ltd. All rights reserved.

Uncertainty and the influence of group norms in the attitude-behaviour relationship

Two studies were conducted to examine the impact of subjective uncertainty on conformity to group norms in the attitude-behaviour context. In both studies, subjective uncertainty was manipulated using a deliberative mindset manipulation (McGregor, Zanna, Holmes, & Spencer, 2001). In Study 1 (N = 106), participants were exposed to either an attitude-congruent or an attitude-incongruent in-group norm. In Study 2(N = 83), participants were exposed to either a congruent, incongruent, or an ambiguous in-group norm. Ranges of attitude-behaviour outcomes, including attitude-intention consistency and change in attitude-certainty, were assessed. In both studies, levels of group-normative behaviour varied as a function of uncertainty condition. In Study 1, conformity to group norms, as evidenced by variations in the level of attitude-intention consistency, was observed only in the high uncertainty condition. In Study 2, exposure to an ambiguous norm had different effects for those in the low and die high uncertainty conditions. In the low uncertainty condition, greatest conformity was observed in the attitude-congruent norm condition compared with an attitude-congruent or ambiguous norm. In contrast, individuals in the high uncertainty condition displayed greatest conformity when exposed to either an attitude-congruent or an ambiguous in-group norm. The implications of these results for the role of subjective uncertainty in social influence processes are discussed. © 2007 The British Psychological Society.

The impact of family forms on interpersonal influence between single parent and full families

The relationship between individual thoughts and the social environment has been widely studied in sociology (Weber, 1968), psychology (Lewin, 1951) and social psychology. The influence of reference groups on individual behaviour is often manifested in the decisions made by consumers while members of these reference groups are often the individual’s friends and acquaintances. Their decisions, their values and norms serve as an example for the individual. In this study the influences of reference groups are examined within the context of the family form in Hungary. The paper focuses on the nature of peer influence in single parent households and full families, to analyse the normative and informational dimensions of peer pressure and communication patterns within the family.

The influence of perception of forgetting and gender, ethnicity, and closeness on likelihood of caregiving

As life expectancy increases, the population of older adults is increasing rapidly. The caregiving of older parents by adult children has become a normative experience. Much of the gerontological literature has examined the caregiving experience, particularly in terms of the stresses involved. However, research is only beginning to examine the factors which motivate adult children to begin caregiving. The research described here examined how an elderly parent's memory behavior might influence caregiving decisions. In addition, gender, ethnicity, and parent-adult child closeness were examined to explore how these individual difference variables might influence those caregiving decisions.^ Participants read one of two vignettes describing a social visit with an elderly widow (target). In the vignette, the elderly target experiences several instances of forgetting. The vignettes depicted forgetting behavior established in pilot work as normal or serious. The normal forgetting vignette did not arouse concern and the serious forgetting vignette did arouse concern when the middle-aged participants imagined their mothers in the role of the vignette target. Participants rated their likelihood of engaging in eight caregiving behaviors if their mothers behaved like the vignette target. They also rated their closeness with their own mothers.^ Multivariate analyses of variance indicated main effects for vignette type, gender, ethnicity, and attachment. The likelihood of caregiving was higher when forgetting was more serious and when participants were female, Hispanic, and were highly attached to their mothers. Interaction effects showed that gender differences decreased with increased seriousness of forgetting, and ethnic differences were only significant for the normal forgetting condition.^ Multiple regression analyses indicated that attachment was the most significant predictor of likelihood of caregiving. Gender and ethnicity predicted specific caregiving behaviors. Females were more likely to engage in phoning and cooking, and Hispanics were more likely to engage in visiting and suggesting mother move in. ^
