    [EN] Rabbit is one of the most versatile livestock species, responding successfully to bio-economic principles, which promote a clever use of resources and their conversion into added value products, such as functional foods (FFs). The excellent nutritive and dietetic properties of rabbit meat justify granting it the attributes of FFs. Based on the premise that it is the consumer who ultimately decides what kind of meat to buy, a consumer focus should be a core factor in private or public meat sector strategies. Following this assumption, the aim of this study is to contribute to understanding Romanian consumer behaviour related to rabbit meat as a functional food and to provide information on how to better market rabbit meat as FF in the domestic market. As far as the authors know, this study is the first one to assess and report on Romanian consumer perceptions, knowledge and behaviours related to rabbit meat. Consequently, the variables investigated reflect rabbit meat consumption habits. They also reveal preferences related to the acquisition of rabbit meat, perceptions on future rabbit meat consumption, perceptions of rabbit meat characteristics, perceptions of rabbit meat main characteristics compared to other types of meat, and rabbit meat consumption deterrents. The survey results show that rabbit meat is perceived as lean and low cholesterol, healthier and tastier than other meats, but more expensive, that its consumption is low, being 2.2 times lower than chicken and 1.8 times lower than pork, and that 29.6% of people surveyed have never eaten rabbit meat. The findings ascertain that the understanding of Romanian consumer behaviour related to rabbit meat as FF is an optimal tool for changing behaviour patterns towards a more sustainable market. The transfer of this knowledge towards marketers mainly focusing on how to increase consumer satisfaction for FFs, especially meat, is the leverage for designing successful businesses regarding market re-orientation, development or even reduction of health cost.This study was partially developed through the research programme “The creation of a model for the evaluation of food quality from the point of view of consumer health and environmental protection”, selected within the bilateral cooperation between the Romanian Academy and Wallonia – WBI, FRS-FNRS. “La prĂ©sente publication a Ă©tĂ© rendue possible grĂące Ă  l’Accord qui lie WBI, le FRS-FNRS et l’AcadĂ©mie Roumaine.Petrescu, DC.; Petrescu-Mag, RM.

    The impacts of human resource management practices and pay inequality on workers' job satisfaction

    Get PDF
    In this paper we investigate the relationship between Human Resource Management (HRM) practices and workers' overall job satisfaction and their satisfaction with pay. To investigate these issues we use British data from the 'Changing Employment Relationships, Employment Contracts and the Future of Work Survey' and the 'Workplace Employment Relations Survey'. After controlling for personal, job and firm characteristics, it is shown that several HRM practices raise workers overall job satisfaction and their satisfaction with pay, but these effects are only significant for non-union members. Satisfaction with pay is higher where performance-related pay and seniority-based reward systems are in place. A pay structure that is perceived to be unequal is associated with a substantial reduction in both non-union members' overall job satisfaction and their satisfaction with pay. Although HRM practices can raise worker job satisfaction, if workplace pay inequality widens as a consequence then non-union members may experience reduced job satisfaction.

    BIOLOGICALLY STRUCTURED MATERIALS

    Biomimetics, biomechanics, and tissue engineering are three multidisciplinary fields that have been contemplated in this research to attain the objective of improving prosthetic implants reliability. Since testing and mathematical methods are closely interlaced, a promising approach seemed to be the combination of in vitro and in vivo experiments with computer simulations (in silico). An innovative biomimetics and biomechanics approach, and a new synthetic structure providing a microenvironment, which is mechanically coherent and nutrient conducive for tissue osteoblast cell cultures used in regenerative medicine, are presented. The novel hybrid ceramic-polymeric nanocomposites are mutually investigated by finite element analysis (FEA) biomimetic modeling, anatomic reconstruction, quantitative-computed-tomography characterization, computer design of tissue scaffold. The starting base materials are a class of innovative highly bioactive hybrid ceramic-polymeric materials set-up by the proponent research group that will be used as a bioactive matrix for the preparation of in situ bio-mineralized techno- structured porous nanocomposites. This study treats biomimetics, biomechanics and tissue engineering as strongly correlated multidisciplinary fields combined to design bone tissue scaffolds. The growth, maintenance, and ossification of bone are fundamental and are regulated by the mechanical cues that are imposed by physical activities: this biomimetic/biomechanical approach will be pursued in designing the experimental procedures for in vitro scaffold mineralization and ossification. Bio-tissue mathematical modeling serves as a central repository to interface design, simulation, and tissue fabrication. Finite element computer analyses will be used to study the role of local tissue mechanics on endochondral ossification patterns, skeletal morphology and mandible thickness distributions using single and multi-phase continuum material representations of clinical cases of patients implanted with the traditional protocols. New protocols will be hypothesized for the use of the new biologically techno-structured hybrid materials

    TRABECULAR PROSTHESES

    The complex biomechanics and morphology of the femur proximal epiphysis are presented. This specific region in the human femur is characterized by high flexibility compared to that of other primates, since evolved lighter and longer due to the human vertical position and more balanced loading. The nature and fine morphology of the femur head and its structural behavior have been investigated. Isotropic and orthotropic trabecular structures, which are not present in other primates, have been associated with compression and tension areas of the femur head. These isotropic/orthotropic trabecular morphologies and allocations govern the stress and strain distribution in the overall proximal femur region. Use of femur proper biofidel modeling while enabling the explanation of physiological stress distribution elucidates the critical mechanical role of the trabecular bone that should be accounted in the design of a new innovative more "biologic" prosthetic system

    A social perspective on soil functions and quality improvement : Romanian farmers’ perceptions

    Get PDF
    Agriculture is a key player in the conservation of natural resources and cultural landscapes and one of the most prominent interfaces between human activity and soil. The present paper reveals a social perspective on soil functions. In this context, it was assumed that perceptions of soil functions could transform themselves into components of agro-ecosystems and influence the whole decision-making process. Therefore, it is indispensable to look at farmers when approaching soil functions. The objective of this study was twofold. Firstly, Romanian farmers' perception of the importance of soil functions was investigated. Secondly, it was revealed how well farmers' perception of soil functions importance and socio-economic variables could predict the "Use of compost". Soil functions were selected based on an extensive literature review. Farmers' perceptions of soil functions and the use of compost as a measure taken to improve soil productivity were studied through a questionnaire applied to a sample of 278 Romanian farmers randomly selected from sixteen villages. Binary logistic regression revealed that the perceived importance of two soil functions could predict the use of compost - "Water quantity regulation" and "Water quality maintenance and enhancement". The study concluded that strengthening the importance of the "Water quantity regulation" function in farmers' minds can stimulate the use of compost. It was also inferred that because younger farmers are more prone to composting, they will be more receptive to marketing actions related to compost use, such as the acquisitions of materials and instruments useful for compost production and use. In a context where a real dialogue to elaborate well-grounded environmental policies is still elusive because of differences between farmers and policy-makers' views, investigation of farmers' perceptions can bring a significant contribution towards a bottom-up approach for sustainable soil management

    Some aspects of the human body's hydraulics

    Get PDF
    This paper presents some aspects related to the human body's hydraulics in the desire to make readers aware of how to maintain all the blood vessels of the human body in order to maintain the entire healthy, functional, young, vigorous circulatory system for a while the longest possible. The problem is complex because it has to be viewed from all points of view and not only as an isolated system in the body, having aspects of feedback on the whole physiopathology belonging to the human body. The highly circulating system needs permanent maintenance. Self-maintenance is done through various physiological mechanisms tightly linked to each other, including the lymphatic, digestive, renal, lung, nervous, glandular system
 It is not possible to completely separate the physiology of a system from the other adjacent systems because they all work synergistically, being permanently controlled by the central and peripheral nervous system

    Biomechanically tunable nano-silica/p-hema structural hydrogels for bone scaffolding

    Get PDF
    Innovative tissue engineering biomimetic hydrogels based on hydrophilic polymers have been investigated for their physical and mechanical properties. 5% to 25% by volume loading PHEMA-nanosilica glassy hybrid samples were equilibrated at 37◩C in aqueous physiological isotonic and hypotonic saline solutions (0.15 and 0.05 M NaCl) simulating two limiting possible compositions of physiological extracellular fluids. The glassy and hydrated hybrid materials were characterized by both dynamo-mechanical properties and equilibrium absorptions in the two physiological-like aqueous solutions. The mechanical and morphological modifications occurring in the samples have been described. The 5% volume nanosilica loading hybrid nanocomposite composition showed mechanical characteristics in the dry and hydrated states that were comparable to those of cortical bone and articular cartilage, respectively, and then chosen for further sorption kinetics characterization. Sorption and swelling kinetics were monitored up to equilibrium. Changes in water activities and osmotic pressures in the water-hybrid systems equilibrated at the two limiting solute molarities of the physiological solutions have been related to the observed anomalous sorption modes using the Flory-Huggins interaction parameter approach. The bulk modulus of the dry and glassy PHEMA-5% nanosilica hybrid at 37◩C has been observed to be comparable with the values of the osmotic pressures generated from the sorption of isotonic and hypotonic solutions. The anomalous sorption modes and swelling rates are coherent with the difference between osmotic swelling pressures and hybrid glassy nano-composite bulk modulus: the lower the differences the higher the swelling rate and equilibrium solution uptakes. Bone tissue engineering benefits of the use of tuneable biomimetic scaffold biomaterials that can be “designed” to act as biocompatible and biomechanically active hybrid interfaces are discussed
