Walking in a winter wonderland? Strategies for Early and Middle Pleistocene survival in mid-latitude Europe

Any occupation of northern Europe by Lower Palaeolithic hominins, even those occurring during full interglacials, must have addressed the challenges of marked seasonality and cold winters. These would have included the problems of: wind-chill and frostbite; duration, distribution and depth of snow-cover; reduced daylight hours; and distribution and availability of animal and plant foods. Solutions can essentially be characterised as a ‘stick or twist’ choice: i.e. year-round presence on a local scale vs. extensive annual mobility. However these options, and the ‘interim’ strategies that lie between them, present various problems, including maintaining core body temperature, meeting the energetic demands of mobility, coping with reduced resource availability and increasing patchiness, and meeting nutritional requirements. The feasibility of different winter survival strategies are explored with reference to Lower Palaeolithic palaeoenvironmental reconstructions and on-site behavioural evidence. Emphasis is placed upon possible strategies for (i) avoiding the excessive lean meat protein problem of ‘rabbit starvation’ (e.g. through exploitation of ‘residential’ species with significant winter body fat and/or by targeting specific body parts, following modern ethnographic examples, supplemented by the exploitation of winter plants); and (ii) maintaining body temperatures (e.g. through managed pyrotechnology, and/or other forms of cultural insulation). The paper concludes with a suggested winter strategy.

The use and impacts of bank support on UK small and medium-sized enterprises

This article examines an under-investigated area in relationship banking, i.e. the use of bank advice and support and its impacts on the financial conditions of small and medium-sized enterprises (SMEs). The findings indicate that the characteristics of businesses and entrepreneurs, among other factors, have determinant effects on the use of bank support by SMEs when they make financial decisions. SMEs can alleviate the severity of their financial problems significantly by using bank support more fully, through developing long-term relationships with banks as primary network partners. The article further recognises the value of advice from banks as a substitute for entrepreneurial human capital, especially when bankers use private information to determine the nature and level of financial and non-financial assistance that they are prepared to supply to their clients.

Managing the complexity of information flow for construction small and medium-sized enterprises (CSMEs) using system dynamics and collaborative technologies

With the increase in e-commerce and the digitisation of design data and information,the construction sector has become reliant upon IT infrastructure and systems. The design and production process is more complex, more interconnected, and reliant upon greater information mobility, with seamless exchange of data and information in real time. Construction small and medium-sized enterprises (CSMEs), in particular,the speciality contractors, can effectively utilise cost-effective collaboration-enabling technologies, such as cloud computing, to help in the effective transfer of information and data to improve productivity. The system dynamics (SD) approach offers a perspective and tools to enable a better understanding of the dynamics of complex systems. This research focuses upon system dynamics methodology as a modelling and analysis tool in order to understand and identify the key drivers in the absorption of cloud computing for CSMEs. The aim of this paper is to determine how the use of system dynamics (SD) can improve the management of information flow through collaborative technologies leading to improved productivity. The data supporting the use of system dynamics was obtained through a pilot study consisting of questionnaires and interviews from five CSMEs in the UK house-building sector.

e-Leadership through strategic alignment: an empirical study of small and medium sized enterprises in the digital age

Small and medium sized enterprises (SMEs) play an important role in the European economy. A critical challenge faced by SME leaders, as a consequence of the continuing digital technology revolution, is how to optimally align business strategy with digital technology to fully leverage the potential offered by these technologies in pursuit of longevity and growth. There is a paucity of empirical research examining how e-leadership in SMEs drives successful alignment between business strategy and digital technology fostering longevity and growth. To address this gap, in this paper we develop an empirically derived e-leadership model. Initially we develop a theoretical model of e-leadership drawing on strategic alignment theory. This provides a theoretical foundation on how SMEs can harness digital technology in support of their business strategy enabling sustainable growth. An in-depth empirical study was undertaken interviewing 42 successful European SME leaders to validate, advance and substantiate our theoretically driven model. The outcome of the two stage process – inductive development of a theoretically driven e-leadership model and deductive advancement to develop a complete model through in-depth interviews with successful European SME leaders – is an e-leadership model with specific constructs fostering effective strategic alignment. The resulting diagnostic model enables SME decision makers to exercise effective e-leadership by creating productive alignment between business strategy and digital technology improving longevity and growth prospects.

How initial vocational education and training (IVET) teachers in Sweden perceive their prospects of being able to prepare upper secondary school pupils for a future occupation

Vocational teachers in Swedish upper secondary schools are a heterogeneous category of teachers, connected to different types of trade. These teachers represent a broad set of trade skills varying in content and character. In their teacher role, they continue to wear the clothes, speak the language, share the culture and remain mentally in their former professions. Still, it is central that they keep up this contact to be able to school the pupils into the environment of the trade in question, but also to help them to understand what skills a profession demands. However, the individual teacher also has to distance himself from the negative elements in the culture of the profession: patterns and habits that, for various reasons, have to be broken or changed. This paper draws attention to the ways in which a group of vocational teachers, who were participants in a project that aimed to train unauthorized vocational teachers, expressed their ambitions to prepare the pupils for a future professional career. When collecting information, we used the degree dissertations they produced and discussed in seminars, and informal dialogues. The result shows that it is important that the instruction location resembles a real working site as far as possible. These places are more or less realistic copies of a garage, a restaurant kitchen, a hairdressing salon, and so on, in order to give the pupils a realistic setting for instruction. However, the fact that these simulated workplaces lack the necessary support functions that exist in a company creates problems, problems which make a lot of extra work for the teachers. Vocational teachers also have to instruct the pupil in the experienced practitioner’s professional skills and working situation, but the pupil herself/himself must learn the job by doing it in practice. Some vocational upper secondary programs lack relevant course literature and the businesses give little support. This also makes extra work for the teachers. Moreover, the distance between the vocational programs and the trainee jobs was experienced as being difficult to overcome. One reason seems to be differences between businesses and differing preconditions between small and big companies’ abilities to take care of these pupils. The upper secondary school vocational programs also play a role in cementing existing gender roles, as well as perpetuating class-related patterns on the labour market.

Health system context and implementation of evidence-based practices-development and validation of the Context Assessment for Community Health (COACH) tool for low- and middle-income settings

Background: The gap between what is known and what is practiced results in health service users not benefitting from advances in healthcare, and in unnecessary costs. A supportive context is considered a key element for successful implementation of evidence-based practices (EBP). There were no tools available for the systematic mapping of aspects of organizational context influencing the implementation of EBPs in low- and middle-income countries (LMICs). Thus, this project aimed to develop and psychometrically validate a tool for this purpose. Methods: The development of the Context Assessment for Community Health (COACH) tool was premised on the context dimension in the Promoting Action on Research Implementation in Health Services framework, and is a derivative product of the Alberta Context Tool. Its development was undertaken in Bangladesh, Vietnam, Uganda, South Africa and Nicaragua in six phases: (1) defining dimensions and draft tool development, (2) content validity amongst in-country expert panels, (3) content validity amongst international experts, (4) response process validity, (5) translation and (6) evaluation of psychometric properties amongst 690 health workers in the five countries. Results: The tool was validated for use amongst physicians, nurse/midwives and community health workers. The six phases of development resulted in a good fit between the theoretical dimensions of the COACH tool and its psychometric properties. The tool has 49 items measuring eight aspects of context: Resources, Community engagement, Commitment to work, Informal payment, Leadership, Work culture, Monitoring services for action and Sources of knowledge. Conclusions: Aspects of organizational context that were identified as influencing the implementation of EBPs in high-income settings were also found to be relevant in LMICs. However, there were additional aspects of context of relevance in LMICs specifically Resources, Community engagement, Commitment to work and Informal payment. Use of the COACH tool will allow for systematic description of the local healthcare context prior implementing healthcare interventions to allow for tailoring implementation strategies or as part of the evaluation of implementing healthcare interventions and thus allow for deeper insights into the process of implementing EBPs in LMICs.

Temperature Dynamics Investigation At Small And Shallow Lakes Using Hydrodynamic Model

A three-dimensional time-dependent hydrodynamic and heat transport model of Lake Binaba, a shallow and small dam reservoir in Ghana, emphasizing the simulation of dynamics and thermal structure has been developed. Most numerical studies of temperature dynamics in reservoirs are based on one- or two-dimensional models. These models are not applicable for reservoirs characterized with complex flow pattern and unsteady heat exchange between the atmosphere and water surface. Continuity, momentum and temperature transport equations have been solved. Proper assignment of boundary conditions, especially surface heat fluxes, has been found crucial in simulating the lake’s hydrothermal dynamics. This model is based on the Reynolds Average Navier-Stokes equations, using a Boussinesq approach, with a standard k − ε turbulence closure to solve the flow field. The thermal model includes a heat source term, which takes into account the short wave radiation and also heat convection at the free surface, which is function of air temperatures, wind velocity and stability conditions of atmospheric boundary layer over the water surface. The governing equations of the model have been solved by OpenFOAM; an open source, freely available CFD toolbox. As its core, OpenFOAM has a set of efficient C++ modules that are used to build solvers. It uses collocated, polyhedral numerics that can be applied on unstructured meshes and can be easily extended to run in parallel. A new solver has been developed to solve the hydrothermal model of lake. The simulated temperature was compared against a 15 days field data set. Simulated and measured temperature profiles in the probe locations show reasonable agreement. The model might be able to compute total heat storage of water bodies to estimate evaporation from water surface.

The Brazilian credit market for small and medium-sized firms: an adaptive marketing approach

Neste trabalho, o mercado brasileiro de crédito para pequenas e médias empresas (PMEs) é analisado sob a perspectiva do marketing adaptativo, em que se assume que atividades mercadológicas como segmentação, gestão de relacionamento com clientes, apreçamento e desenvolvimento de produtos, são determinadas pela utilidade obtida por agentes de mercado ao atenderem a demanda. Identifica-se que a existência de assimetria de informações e de custos de transação limita e direciona as atividades de marketing no mercado estudado. A partir de uma amostra com 65.535 propostas de crédito, recebidas e avaliadas por um grande banco brasileiro entre janeiro de 2004 e setembro de 2006, estima-se a utilidade do banco em operações de crédito. Adicionalmente, 17.149 transações de empréstimos concedidos pelo banco ao segmento de pequenas empresas entre abril de 2006 e março de 2007, são investigadas. Finalmente, um conjunto de dados com 1,636 registros obtidos pela junção das bases de dados de propostas e de transações mencionados, é analisado em termos das relações entre taxas de juros e os totais de cobertura oferecidas por meio de garantias de crédito. Os resultados revelam a existência de um ambiente de marketing adaptativo, em que os pequenos tomadores de crédito produtivo são racionados, e aceitam pagar taxas de juros mais elevadas do que outros segmentos. Produtos de créditos baseados em garantias líquidas e com altas taxas de juros são desenvolvidos para suprir de maneira oportuna este segmento racionado de pequenas empresas. Ademais, a utilidade do banco em operações de crédito é afetada pela informação privada que captura ao longo de relacionamentos mantidos com seus cientes. Os resultados implicam que o sistema de marketing financeiro brasileiro não desempenha papel formativo no desenvolvimento econômico, que seria de fomento ao crédito produtivo por meio de empréstimos a baixo custo para pequenas e médias empresas. Um sistema formativo de marketing é improvável em um ambiente com informação imperfeita, como o mercado de crédito brasileiro. O estudo traz informações úteis àqueles interessados no desenvolvimento de mercados de crédito produtivo, tais como profissionais de instituições financeiras; agentes responsáveis por políticas públicas e monetárias de fomento ao crédito; e empreendedores de pequeno e médio porte que necessitem de financiamento externo para seus negócios.

A mão-de-obra como barreira ao desenvolvimento empresarial

As recentes transformações no mundo geraram, para a atualidade, uma exigência peculiar quanto à capacitação dos trabalhadores, estabelecendo padrões inéditos de qualificação, devido à competição mais acirrada por causa da abertura dos mercados, do processo irreversível de globalização, e, sobretudo, a crescente utilização de novas tecnologias que se tomaram cada vez mais corriqueiras na sociedade contemporânea. A preocupação com a necessidade de formar trabalhadores hábeis para enfrentar os desafios que essa nova conjuntura impõe é compartilhada pelos governos de diversas nações que se empenham em reformular as diretrizes básicas para a educação visando, além do emprego, o desenvolvimento humano sustentável. Este estudo investigou um dos obstáculos ao progresso de micro e pequenas empresas e sua influência no desenvolvimento organizacional: a qualificação da mão-de-obra. Tema multifacetado envolvendo diversas instâncias: governos, empresas e, inclusive, o próprio trabalhador com suas dificuldades de formação num mundo em constante transformação. Este trabalho, ainda que se refira a ações governamentais, e, a outros aspectos mais gerais, privilegia a dificuldade própria do gerente, e sua perspectiva, que, para atender as demandas de serviço, não encontra mão de obra qualificada disponível. O referencial teórico utilizado foi o dos autores que adotam os paradigmas do pósfordismo e do pós-modernismo, aliado à pesquisa bibliográfica, para conceituar as habilidades exigidas dos trabalhadores pelas organizações e as ações dos governos visando o emprego. Além disso, foram feitas entrevistas com gestores de mão-de-obra e empresários de micro e pequenas empresas instaladoras de infra-estrutura para o setor elétrico e de telecomunicações, que prestam serviços nas regiões Centro-Oeste, Sudeste e Sul do Brasil. A pesquisa concluiu que, no setor estudado, não há desemprego ou excesso de mão de obra, mas despreparo, ausência de mão de obra qualificada para ocupação de vagas disponíveis. O despreparo é detectado em habilidades básicas como leitura e escrita, o que impede tanto a especialização do trabalhador e seu aprimoramento, quanto o desenvolvimento sustentável da pequena e da micro empresa no Brasil. Os resultados desta pesquisa indicaram que a qualificação básica da mão de obra é um obstáculo ao desenvolvimento que vai além do âmbito da organização empresarial.

Micro e pequenas empresas: a importância de aprender a empreender

As micro e pequenas empresas representam 99,2% das empresas no Brasil, empregam 57,2% da força de trabalho por isso são imprescindíveis para a economia e o desenvolvimento do país, apesar desses números representativos a grande preocupação é manter essas empresas ativas devido ao grande índice de mortalidade que representa em média 50%, tendo como um dos principais fatores condicionantes a falha gerencial na condução da empresa. Micro e pequenas empresas: A importância de apreender a empreender é o tema desta dissertação, que tem, por objetivo avaliar o conhecimento que os micro e pequenos empresários têm sobre a importância do desenvolvimento pessoal no gerenciamento de seus negócios. Por tratar-se de micro e pequenas empresas elegemos o Sebrae, instituição de apoio às micro e pequenas empresas de São Luís do Maranhão para investigar através de pesquisa de campo qual o conhecimento que os micro e pequenos empresários tem sobre está instituição seus produtos e serviços. O referencial teórico demonstrou que treinamento, capacitação, planejamento e aprendizado contínuo são ferramentas eficazes na administração organizacional de uma empresa. Na pesquisa de campo identificou-se que 76% dos empresários não buscaram nenhuma ajuda especializada antes de abrir seus negócios, apenas 45% dos empresários conhecem a marca do Sebrae e 54% não conhecem os produtos e serviços que o Sebrae São Luís oferece.

Entry strategies into biosimilars: assessment of entry modes into the field of biosimilars from the perspective of pharmaceuticals, generics and biologics companies

Indústria farmacêutica de hoje está em transição. Como grandes blockbuster drogas estão perdendo ou estão prestes a perder a proteção de patente, e as grandes empresas farmacêuticas não estão substituindo os produtos com novas drogas químicas inovadoras, a indústria busca novas áreas de crescimento. Uma dessas áreas é o mercado de biossimilares, que está sendo inseridos por produtos farmacêuticos, genéricos e empresas de produtos biológicos. Mesmo que o grande potencial de mercado será acordado por volta de 2020, quando importantes blockbusters biológicos perder a proteção de patente, as empresas precisam decidir logo se querem participar ou não devido a elevadas barreiras à entrada técnicos, bem como de desenvolvimento de longo prazos. Como todas as empresas vêm de diferentes origens, compreendem capacidades diferentes e têm diferentes incentivos de entrada, a questão que surge é se esses fatos estão relacionados com as suas estratégias de entrada correspondentes. A tese utiliza estudos de caso de cada segmento da indústria farmacêutica - produtos farmacêuticos, biológicos e genéricos - e examina através de entrevistas semi-estruturadas, por isso que os participantes do estudo de caso entrevistados explicitamente escolhido sua estratégia de entrada. Os dados de entrevistas será então ligada a quadros estratégicos da revisão da literatura e irá ser utilizado para uma comparação global e análise. O estudo revelou que o fundo do participante do mercado que influenciam a sua estratégia de entrada. Os principais pontos de influência derivam tanto as barreiras à entrada, bem como os incentivos de entrada. A tese não é possível determinar o sucesso futuro do modo de entrada analisados no novo mercado.
