Friendly amendment: a commentary on Doyle and Ford's proposed re-definition of 'mental model'

Some amendments are proposed to a recent redefinition of the mental model concept in system dynamics. First, externalised, or articulated mental models should not be called cognitive maps; this term has a well established, alternative meaning. Second, there can be mental models of entities not yet existing beyond an individual's mind; the modelling of planned or desired systems is possible and recommended. Third, saying that mental models maintain social systems connects with some exciting research opportunities for system dynamics; however, it is probably an accidental distraction from the intended meaning of the redefinition. These minor criticisms apart, the new definition of mental model of a dynamic system is welcomed as a useful contribution to both research and practice.

Back to the future: implications for the field of HRM of the multistakeholder perspective proposed 30 years ago

Thirty years on from the seminal works on human resource management (HRM) by Beer et al., we examine how the subject has developed. We offer a normative review, based on that model and critique the assumption that the business of HRM is solely to improve returns to owners and shareholders. We identify the importance of a wider view of stakeholders to practitioners and how academic studies on the periphery of HRM are beginning to adopt such a view. We argue that the HRM studies so far have given us much valuable learning but that the subject has now reached a point where we need to take a wider, more contextual, more multilayered approach founded on the long-term needs of all relevant stakeholders. The original Beer et al. model remains a valuable guide to the next 30 years of HRM.

Proposed feasibility oversight for pre-pack administration in England and Wales: window dressing or effective reform?

The 2014 Graham proposals aimed at reducing recidivism are unlikely to achieve the desired goals. It is argued that due consideration must be had for the future of the rescued entity. Further, both the viability review and the proposed capital structure of the rescued entity must be carefully assessed.

Experimental evidence for proposed transformation pathway from the inverse hexagonal to inverse diamond cubic phase from oriented lipid samples

A macroscopically oriented inverse hexagonal phase (HII) of the lipid phytantriol in water is converted to an oriented inverse double diamond bicontinuous cubic phase (QIID). The initial HII phase is uniaxially oriented about the long axis of a capillary with the cylinders parallel to the capillary axis. The HII phase is converted by cooling to a QII D phase which is also highly oriented, where the cylindrical axis of the former phase has been converted to a ⟨110⟩ axis in the latter, as demonstrated by small-angle X-ray scattering. This epitaxial relationship allows us to discriminate between two competing proposed geometric pathways to convert HII to QIID. Our findings also suggest a new route to highly oriented cubic phase coatings, with applications as nanomaterial templates.

A proposed EPR approach to evaluating agonist binding site of a peptide receptor

Angiotensin II (Ang II) and its transmembrane AT(1) receptor were selected in order to test an innovative strategy that might allow the assessment of the agonist binding site in the receptor molecule. With the use of the 2,2,6,6-tetramethylpiperidine-1-oxyl-4-amino-4-carboxylic acid (TOAC) paramagnetic probe, a biologically active agonist (TOAC(1)-Ang II), as well as an inactive control (TOAC(4)-Ang II) analogs were mixed in solution with various synthesized AT(1) fragments. Comparative intermolecular interactions, as estimated by analyzing the EPR spectra of solutions, suggested the existence of an agonist binding site containing a sequence composed of portions of the N-terminal (13-17) and the third extracellular loop (266-278) fragments of the AT(1) molecule. Therefore, this combined EPR-TOAC approach shows promise as an alternative for use also in other applications related to specific intermolecular association processes.

A proposed Model for Country Branding : an experimental Application on Nigeria

In the era of globalization, countries compete with each other for attention, respect and trust of potential consumers, investors, tourists, media and governments of other nations. Branding is the most powerful tool that a nation can utilize for effective differentiation strategies and for creating competitive advantage over other nations. Unfortunately, not every nations or destination marketers have a broad understanding of the concept of branding and how a country can be successfully branded. Hence, this study has proposed a model that could be used as a valuable guide for country branding. Also the model is recommended for countries struggling with image crisis; on the mission to improve the image internationally. Nigeria is a good example of countries with image crisis; it is one of the most populated countries in the world with a population of about 160 million inhabitants and growth rate of 2.553percent annually. Despite the abundant resources (e.g. coal, petroleum, natural gas etc.) that the nation is endowed with, it is quite disappointing that the population below poverty line is still at the alarming rate of 70percent of the total population. The mismanagement and poor leadership of the nation characterised by corruption, fraud, embezzlement of public fund etc. has culminated into serious image crisis that is slowing down the potential for investment and economic growth. However, there has been series of image rebranding campaigns but no tangible achievement has been recorded. It is quite questionable though, if image rebranding will provide the kind of future that Nigeria envisaged, considering the socio-political situation and the economic imbalance; compounded by the obvious fact that the nation has no known brand. Therefore, this paper argues that there is need to redirect the effort invested on image rebranding to the creation of a unique and competitive brand for the country. It was established from the study that a nation’s brand is capable of improving the reputation of the nation as well as stimulate the expectation of the target audience. However, it was also established from the study that a wrong approach to branding could mislead the target audience and attract negative publicity. Hence, as a contribution of the study to the field of branding, a model was proposed as a functional guide for country branding. Also, considering the abysmal performance of Nigeria’s image in the international community and to strengthen the argument that brand creation is required for the country; an experimental application of the proposed model was conducted using Nigeria as the case country. The first phase of the model suggested a major improvement in the society; this is required to further enhance the strengths of the country and to motivate the much needed community participation and confidence in the brand creation. It is the conclusion of the study that a strong nation brand can offset the image problem if it is built on something concrete, genuine, and uniquely identifiable with the country, capable of connecting to the cognitive psychology of the target audience.

Preparers’ and non-preparers’ lobbying on the proposed prohibition of goodwill amortisation in ED3 ‘business combinations’

In this paper preparers’ and non-preparers’ positions regarding accounting for goodwill are examined through studying submitted comment letters on ED3 ‘Business Combinations’. Preparers have, because of economic consequences, incentives to lobby for the non-amortisation approach and non-preparers for the amortisation approach. As hypothesised, non-preparers are found to support amortisation of goodwill to a greater extent than do preparers. Moreover, the two groups’ supportive arguments, i.e. how they argue for or against the non-amortisation or amortisation approach, are studied. Again, as hypothesised, the results show that the two groups use the same type of ‘sophisticated’ framework based arguments instead of economic consequences arguments. Taken together the examination of the comment letters thus indicates that both preparers and non-preparers point at conceptual strengths and weaknesses, instead of pointing at the real cause of the lobbying activities, i.e. perceived economic consequences, when they try to affect the final outcome of the standard. These findings confirm earlier research which has suggested that self-interested lobbyists use accounting theories and concepts as useful justifications.

KClone: A Proposed Approach to Fast Precise Code Clone Detection

In all applications of clone detection it is important to have precise and efficient clone identification algorithms. This paper proposes and outlines a new algorithm, KClone for clone detection that incorporates a novel combination of lexical and local dependence analysis to achieve precision, while retaining speed. The paper also reports on the initial results of a case study using an implementation of KClone with which we have been experimenting. The results indi- cate the ability of KClone to find types-1,2, and 3 clones compared to token-based and PDG-based techniques. The paper also reports results of an initial empirical study of the performance of KClone compared to CCFinderX.

Draft Proposed Public Transportation Routes for Waterville, ME

Currently, there is a public bus transportation route in Waterville, Maine. However, this system could be improved. Our goal was to use GIS to find optimal public transportation routes throughout the city based on given points of interest and high population density areas. Three different groups of points of interest were created in the North, West, and South sections of Waterville. Using the Network Analyst tool, which calculates optimal routes, using existing street data, based on the input of stops, barriers, and impedance, we ran an analysis of what we thought would be the routes that best served the greatest number of people. Two different sets of routes were found: one with length as the impedance (the shortest length between the selected stops was favored), and one with population density as the impedance (the roads with the highest population density were favored). Finally, the times of the resulting routes (given a constant speed limit of 25 mph) were calculated and evaluated.

Biodiesel do dendê: um estudo de viabilidade econômico financeira no Estado do Pará

O objetivo deste estudo é analisar três modelos de operação de uma usina de extração de óleo de palma, de óleo de palmiste, e de biodiesel, respectivamente, em conjunto com a produção de dendê pela agricultura familiar, visando o fornecimento exclusivo de matéria-prima para a indústria através da parceria com Programa Nacional da Agricultura Familiar. O projeto consiste na construção de uma usina de grande porte, a partir de investimentos de fontes públicas e privadas voltados à construção do complexo industrial e ao financiamento da implantação do cultivo de dendê pelos agricultores. Foram construídos quatro cenários, onde foram analisados os indicadores de performance econômico-financeira de avaliação do arranjo produtivo da indústria e da parte agrícola. Esses cenários visam a tomada de decisões de investimentos, através da utilização dos indicadores econômico-financeiros clássicos para avaliação da viabilidade do dendê como matéria-prima para o complexo industrial da usina. Entre os indicadores utilizados neste trabalho podemos citar como principais: o VPL (Valor Presente Líquido) e a TIR (Taxa Interna de Retorno), e indicadores secundários utilizados como suporte para as análises, tais como Payback Descontado, TIRM (Taxa Interna de Retorno Modificada), dentre outros. Além de indicadores sociais, como geração de renda para as famílias de agricultores, com o objetivo principal de criar valor monetário, gerar emprego e renda e pagar os recursos dos investidores púbicos. A implantação do dendezal está fundamentada no Zoneamento Agroecológico do dendê e será executada em áreas degradas por pastagens para garantir a sustentabilidade, contribuir para a recuperação ambiental através do sequestro de carbono e diminuir a pressão sobre as florestas nativas. Consequentemente, espera-se que o projeto contribua para evitar o avanço do desmatamento na região da Amazônia legal. Para tanto, foram realizadas visitas às plantações de dendê e à usina da Biopalma. Também foram realizadas visitas à Embrapa Ocidental na cidade de Manaus e Embrapa na Cidade de Campinas. Foi proposto um modelo de análise econômica financeira baseado em implantação de uma usina de grande porte para a produção de Biodiesel no Estado do Pará. O estudo apresentou, dentre suas limitações, o fato de ser complexo e amplo. A inexistência de projetos de usina grande envergadura totalmente implantados e funcionando com emprego de tecnologia e capital intensivo, como também a impossibilidade de se realizar esta pesquisa de amplo espectro sem um número consideravelmente maior de organizações envolvidas. Como resultado, os indicadores economicos analisados mostram que há viabilidade do projeto em três dos quatro cenários construídos, demonstrando que o capital dos investidores públicos, privados e do agricultor familiar serão remunerados utilizando às taxas de juros, prazos, condições do mercado de capitais. O objetivo é atrair investimentos para a produção de biodiesel, implantação de empreendimentos agrícolas, indústriais, geração emprego e renda para Agricultura Familiar na cadeia produtiva do dendê.

Gestão de centros históricos: uma avaliação da política de requalificação urbana de Natal/RN

From the second half of the century XX, in many Brazilian cities, the "historic centers" stop being the most densely populated areas of the city, accumulate degradation of the built environment and its functions have physical, social and economic resignified when also intensified interventions in these same centers Historic focused its redevelopment. This work aims to reflect on the experience of urban regeneration in the historic center of Natal, addressing the strategies adopted in the implementation of public policies and how these improve the effectiveness of actions, processes and outcomes for which turn the management of the historic center in question. In Natal, is identified in the neighborhoods of the Upper Town and Ribeira, the historic city center, a large distortion of their ancient architectural complex, the use of sub-urban infrastructure and emptying in the evenings and weekends. Shares redevelopment of the historic center of Natal are considered late, it is only recently that these neighborhoods were objects of policies and projects generally aimed at enhancing the cultural attraction of the area, and not always, it can be said that they have relevance in development process of the city. Added to this, there is the slowness of the interventions, although the zoning as an area of historic preservation has been done for over two decade. In Natal, the ideas of sustainable development articulated a proposed redevelopment of its historic center is still far from being achieved, but on the other hand, the latest phase of implementation of plans and projects in the area, indicating the intention to transform practical experience in the formulations and proposals in relation to these ideals

New constraints on ages of glasses proposed as reference materials for fission-track dating

New analyses have been performed in order to enhance the data-set on the independent ages of four glasses that have been proposed as reference materials for fission-track dating. The results are as follows. Moldavite - repeated (40)Ar/(39)Ar age determinations on samples from deposits from Bohemia and Moravia yielded an average of 14.34 +/- 0.08 Ma. This datum agrees with other recent determinations and is significantly younger than the (40)Ar/(39)Ar age of 15.21 +/- 0.15 Ma determined in the early 1980s. Macusanite (Peru) -four K-Ar ages ranging from 5.44 +/- 0.06 to 5.72 +/- 0.12 Ma have been published previously. New (40)Ar/(39)Ar ages gave an average of 5.12 +/- 0.04 Ma. Plateau fission-track ages determined using the IRMM-540 certified glass and U and Th thin films for neutron fluence measurements agree better with these new (40)Ar/(39)Ar ages than the previously published ages. Roccastrada glass (Italy) - a new (40)Ar/(39)Ar age, 2.45 +/- 0.04 Ma, is consistent with previous determinations. The Quiron obsidian (Argentina) is a recently discovered glass that has been proposed as an additional reference material for its high spontaneous track density (around 100 000 cm(-2)). Defects that might produce spurious tracks are virtually absent. An independent (40)Ar/(39)Ar age of 8.77 +/- 0.09 Ma was determined and is recommended for this glass. We believe that these materials, which will be distributed upon request to fission-track groups, will be very useful for testing system calibrations and experimental procedures.

Proposta de zoneamento geoambiental do município do Crato/CE

The geo-environmental zoning is an important means to plan the management of the territory, once it is the result of integration of different elements of the physical environment. The Municipality of Crato has a diversity of geo-environmental systems due to its complex landscape, which characterization and delimitation will contribute to the most appropriate occupation and the fewer prejudicial to municipal area. This study, which was supported by geo-systemic theory, searched to reach the following objectives: to elaborate a proposal of geo-environmental zoning; to characterize identified and demarcated geo-environmental systems, including their potentiality and limitations of land use and human occupation; and to generate a database on digital maps through GIS Geographic Information System. Four geo-environmental systems were identified (Chapada do Araripe: plateau and hillside, Massif and residual crest, Sertão of peripheric southern depression and fluvial Plains) and ten geo-environmental subsystems (Eastern plateau covered by cerradão/cerrado, Western plateau covered by cerrado/carrasco, Northern-west hillside, central residual Massif, Northern Residual Massifs, Sertaneja depression dominated by sedimentary materials, Sertaneja depression dominated by embasement crystalline material; wet fluvial plains and dry fluvial plains). The identified system and subsystem are similar to those proposed by FUNCEME in spite of some changes due to the more detailed mapping
