    \ua9 2024 Elsevier Ltd. Past research analyzes employee engagement in pro-environmental behavior by assuming all employees are similar in their values, beliefs, and norms (VBN). We argue that a segmented approach is more effective in understanding workplace pro-environmental behaviors (PEBs) and seek to develop a typology of employees. Analyzing data from 702 office employees in the UK, this study yields a more finely grained segmentation of employee differences regarding environmental dimensions, personality traits, behaviors, and perceptions. Based on a cluster analysis methodology, this paper identifies three distinct employee segments: ‘Acorns,’ ‘Saplings,’ and ‘Trees.’ Theoretically, our findings suggest that the VBN theory should be expanded by integrating personality traits, and that organizational environmental policy makers should pay attention to the green subcultures that may form within clusters. Practically, our typology helps organizations design interventions to target different groups of employees with customized motivational strategies, communication tactics, and engagement approaches

    Norway spruce, Picea abies (L.) Karst. is the most important conifer species in Romania and the mostplanted tree species in the Carpathian Mountains. Here we compare the genetic diversity of four Norwayspruce clonal seed orchards and two seed stands located in the Eastern Carpathians. A set of highlypolymorphic nuclear microsatellite markers was used. The analysis of genotypic identity of ramets for eachNorway spruce clone in all seed orchards indicated that nearly all sampled ramets (97%) were geneticallyidentical. The genetic diversity in seed orchards (He=0.700) was slightly smaller compared to the seed stands(He=0.718). Allelic richness was higher in seed stands (10.874), compared to clonal seed orchards (8.941).The Bayesian analysis indicated a genetic structure with two clusters, one corresponding to the clonal seedorchards and a second one consisting of the two seed stands. Our results provide valuable information for themanagement of Norway spruce seed orchards in Romania

    The paper presents Intelligent Control Interfaces (ICIs) for real-time control for terrestrial mobile robots or unmanned aerial robots in order to improve the navigation performances. Intelligent control interfaces using advanced control strategies adapted to robot environment are presented, implemented through IT & C techniques with fast processing and real-time communications in order to develop a versatile, intelligent and portable VIPRO Platform with behavior of e-learning platform, which allows achievement inter-academic research networks and building new intelligent vectors robots. Implementation of ICIs laws in the intelligent real time control interfaces depends on the particular circumstances of the characteristics model used and the exact definition of optimization problem. The results led to the development of the ICI interfaces through image analysis using Images Operation Sampling & Quantization (IOSQ)

    Case Studies on Impediments to Exports in Small Transition Economies

    Get PDF
    This series of enterprise case studies grew out from a 1995-1996 research project at IIASA. It acknowledged the importance of export development for the recovery of the economies of Central and Eastern Europe following their deep transformational recession in 1990-1994. The main goal was a systematic empirical analysis of the different kinds of impediments to exports in various small East European countries. The project included the coordinated elaboration of country studies for seven small transitional economies (Bulgaria, Czech Republic, Estonia, Hungary, Latvia, Romania, Slovakia and Slovenia) and the writing of three topical studies. The authors of the country studies and the author of the topical study on Russia were requested to base their work on 20 enterprise case studies each (eventually the Russian study was based on 10 cases). Before the start of the research a common scheme of the enterprise case studies was discussed and agreed upon with the authors. After completing their work the authors were asked to supplement a short version of their case studies to their main text. Eventually it was decided that, due to the length of the full text, two related publications would be arranged, one book made up of the country studies and topical studies, and another of the enterprise case studies. The book was published by Edward Elgar: Cooper, R. and GĂĄcs, J. (Eds.) (1997) Trade Growth in Transition Economies: Export Impediments for Central and Eastern Europe, Edward Elgar, Cheltenham, UK. The second publication is the present series of case studies

    Insights on the mixtures of imidazolium based ionic liquids with molecular solvents

    Get PDF
    The properties of ionic liquid (1-ethyl-3-methylimidazolium BF4 and 1-butyl-3-methylimidazolium BF4) + solvents (water, ethylene glycol or dimethylformamide) mixtures are studied in the full composition range as a function of mixture composition and temperature. These mixed fluids are characterized by selected physical properties and microscopic studies using density functional theory and molecular dynamics simulations. The reported results showed large non-ideal mixtures, which are caused by strong anion (BF4) – molecular solvent hydrogen bonding. Likewise, the interaction of ions, evolves from anion-cation pairs solvated by molecular solvents, for mixtures rich in molecular solvent, to large ionic aggregates for ionic liquid rich mixtures separated by a transitional composition regime. The large non-linearity of the evolution of microscopic properties with mixture composition is the origin of macroscopic thermodynamic deviations from ideality.Junta de Castilla y León (Spain, project BU324U14

    Characterisation of aggregates of cyclodextrin-drug complexes using Taylor Dispersion Analysis

    Get PDF
    There is a need to understand the nature of aggregation of cyclodextrins (CDs) with guest molecules in increasingly complex formulation systems. To this end an innovative application of Taylor dispersion analysis (TDA) and comparison with dynamic light scattering (DLS) have been carried out to probe the nature of ICT01-2588 (ICT-2588), a novel tumor-targeted vascular disrupting agent, in solvents including a potential buffered formulation containing 10% hydroxypropyl-ÎČ-cyclodextrin. The two hydrodynamic sizing techniques give measurement responses are that fundamentally different for aggregated solutions containing the target molecule, and the benefits of using TDA in conjunction with DLS are that systems are characterised through measurement of both mass- and z-average hydrodynamic radii. Whereas DLS measurements primarily resolve the large aggregates of ICT01-2588 in its formulation medium, methodology for TDA is described to determine the size and notably to quantify the proportion of monomers in the presence of large aggregates, and at the same time measure the formulation viscosity. Interestingly TDA and DLS have also distinguished between aggregate profiles formed using HP-ÎČ-CD samples from different suppliers. The approach is expected to be widely applicable to this important class of drug formulations where drug solubility is enhanced by cyclodextrin and other excipients

    Encouraging environmental sustainability through gender : a micro-foundational approach using linguistic gender marking

    Get PDF
    While studies show that organizational diversity is beneficial to organizations’ practice of environmental sustainability, we know very little about the effect that the gender of an individual director can have on sustainability practice. In this empirical paper, we employ a micro-foundational approach to examine whether the number of women on an organization’s board of directors has a direct effect on its attitude towards environmental sustainability, regardless of the national culture in which the organization is located. Culture in this study is measured through grammatical gender marking, a unique approach to measuring female-oriented cultural effects. Previous studies show that certain cultures have more gender roles than others, which in turn affects general and organizational behavior in that society. Grammatical gender marking enables us to study the impact of gender of the individual director on the organization’s attitude towards environmental sustainability across cultures, by empirically examining data from 71 countries, sampling a total of 4,500 organizations for multiple years and industries. Our findings show that organizations become significantly more proactive in environmental sustainability with the appointment of even one woman to the board of directors, regardless of the local culture. We further show that the organization’s level of disclosure regarding its sustainability activities, increases with the number of women on the board of directors. Our data also show a significantly negative relationship between various gender-based language indices and the presence of women on the board of directors. In cultures defined by a language that has clear grammatical gender markings, there is a tendency to appoint fewer women to boards of directors, thereby influencing indirectly the organization’s attitude towards environmental sustainability
