Capabilities and competitiveness of Chinese state owned manufacturing enterprises:what has been learned over 20 years and what remains to be learned

Technological capabilities in Chinese manufacturing have been transformed in the last three decades. However, the extent to which and how domestic market oriented state owned enterprises (SOEs) have developed their capabilities remain important questions. The East Asian latecomer model has been adapted to study six Chinese SOEs in the automotive, steel and machine tools sectors to assess capability levels attained and the role of external sources and internal efforts in developing them. All six enterprises demonstrate high competence in operating established technology, managing investment and making product and process improvements but differ in innovative capability. While the East Asian latecomer model in which linking, leveraging and learning explain technological capability development is relevant for the companies studied, it needs to be adapted for Chinese SOEs to take account of types of external links and leverage of enterprises, the role of government, enterprise level management motives and means of financing development.

The Central Agency for Jewish Education: Fifty years of Jewish education in Dade County

The purpose of the study was to provide a historical record of the Bureau of Jewish Education/Central Agency for Jewish Education and its role in Jewish education in Miami since its inception in 1944 as well as to provide a sociological context within which to view the growth and development of the community. During the past 50 years of the Agency's existence, Dade County's Jewish population has undergone many changes including a huge population increase in the 1960s and 1970s and then a decrease in the 1980s and 1990s, and a shift from postwar business class of store owners to turn of the century professional class.^ The methodology used in this study was threefold. First, document analysis of formal and informal documents dating from 1944 to the present was conducted. Second, personal interviews were conducted with the Executive Directors of the B.J.E./C.A.J.E., long-time B.J.E./C.A.J.E. staff, present staff, Greater Miami Jewish Federation leaders, and lay leadership of C.A.J.E. Third, national trends in Jewish education were cited as a basis for the comparison and contrast of the achievements of C.A.J.E.^ The historiography concluded that the Agency had come full circle in its programs. Analysis of the services provided to religious and day schools, early childhood education, the High Schools, teacher services, adult education, and the library indicated that in some areas C.A.J.E. was an innovator, in other areas it followed national trends, and in others it was deficient. Recommendations included a reeducative process for the community with Jewish education made top priority, more visibility and publicity for the work of C.A.J.E. that would enhance its prestige and improve support, and holistic planning of programs for the future. ^

Changes in the prevalence of breast feeding in preterm infants discharged from neonatal units : a register study over 10 years

Objective: There are indications that the prevalence of exclusively breastfed preterm infants is decreasing in Sweden. The objective was to investigate trends in exclusive breast feeding at discharge from Swedish neonatal units and associated factors in preterm infants. Design, setting and participants: This is a register study with data from the Swedish Neonatal Quality Register. Data from 29 445 preterm infants (gestational age (GA) <37 weeks) who were born during the period 2004–2013 were retrieved. Data included maternal, perinatal and neonatal characteristics. Data were analysed for the whole population as well as for 3 GA groups. Results: From 2004 to 2013, the prevalence of exclusive breast feeding decreased, in extremely preterm (GA 22–27 weeks) from 55% to 16%, in very preterm (GA 28–31 weeks) from 41% to 34% and in moderately preterm infants (GA 32–36 weeks) from 64% to 49%. The decline was statistically significant (p<0.001) in all 3 GA groups. This decline remained significant when adjustments were made for factors negatively associated with exclusive breast feeding and which became more prevalent during the study period, that is, small for GA (all groups) and maternal mental illness (very preterm and moderately preterm infants). Conclusions: In the past 10 years, Sweden has experienced a lower rate of exclusive breast feeding in preterm infants, especially in extremely preterm infants. The factors analysed in this study explain only a small proportion of this decline. The decline in exclusive breast feeding at discharge from neonatal units raises concern and present challenges to the units to support and promote breast feeding.

O efeito tardio da prática da amamentação na densidade mineral óssea de mulheres na pós-menopausa: revisão sistemática de estudos observacionais

A amamentação representa um período de intensa mobilização óssea para produção de leite. Durante esta fase, a mulher sofre uma grande perda de massa óssea com evidências de recuperação após o desmame. Atualmente este tem sido um período preocupante na vida mulher, pois há suspeitas desta perda óssea na lactação gerar um efeito tardio na densidade mineral óssea (DMO) quando esta mulher está na pós-menopausa. A DMO reduzida é o principal fator de risco para a osteoporose que afeta em torno de 200 milhões de mulheres com mais de cinquenta anos no mundo. O objetivo do presente trabalho foi avaliar o efeito da prática da amamentação na densidade mineral óssea de mulheres na pós-menopausa. Para isto, foi realizada uma revisão sistemática da literatura. A busca de artigos foi feita em bases dados (Lilacs, Medline via Pubmed e Scopus) complementada por checagem manual de referências. Foi identificado um total de 181 artigos e, após aplicação dos critérios de inclusão, selecionados 24 artigos para a revisão sistemática. Os resultados dos diversos estudos são divergentes em questões metodológicas, de classificação da duração da amamentação, quanto às variáveis confundidoras, grupo de idade e etnia, o que dificulta a comparabilidade entre eles. Parte dos estudos referem algum tipo de efeito (positivo ou negativo) e outra parte não, sendo mais frequente a observação de uma correlação inversa entre a amamentação e a densidade mineral óssea em pós-menopausadas. Porém, quando outras variáveis (número de gestações, idade, tempo desde a menopausa, entre outras) são consideradas na análise em conjunto com a amamentação, este último perde a relação de significância. Ainda são necessários mais estudos com melhor rigor metodológico para avaliar se de fato o efeito pode ser atribuído à amamentação ou a outros fatores que também estão relacionados com a densidade mineral óssea na pós-menopausa.

Interfaces e inquietações no diálogo entre Kierkegaard e Foucault - filosofia antiga, psicologia e processos de subjetivação

A presente tese inicia-se por uma encruzilhada e um segredo: na encruzilhada está a psicologia, entre os apelos instrumentais, antropológicos e neurocientíficos; já o segredo refere-se à quase desconhecida leitura de Kierkegaard por Foucault. Os dois filósofos se inscrevem na esteira da experimentação filosófica, caminho oposto ao da metafísica. Experimentação, aqui, não diz respeito a qualquer empirismo; inspira-se nos exercícios espirituais da Antiguidade grega e romana, e nas práticas da ironia, do cuidado de si e da parresía filosófica. As aproximações possíveis entre o pensamento de Kierkegaard e o de Foucault por esse viés da filosofia antiga, visam a contribuir para uma compreensão da psicologia e de suas práticas que permita o enfrentamento dos dilemas acima referidos, ou seja, os instrumentais, antropológicos e neurocientíficos. O percurso do trabalho tem como ponto de partida as suspeitas direcionadas à psicologia, desde o questionamento colocado por Canguilhem há mais de cinqüenta anos acerca das intenções pouco claras da disciplina, passando pelas críticas aos processos de subjetivação psicologizantes, até chegar ao grave enquadramento contemporâneo que busca convencer os sujeitos de que são, em última análise, nada mais do que cérebros. Os processos de subjetivação engendrados pelas práticas psi se vêem, pois, colocados hoje frente a impasses de difícil solução. Tantas são as suspeitas e temores quanto aos efeitos psi, que os próprios profissionais da área têm, em muitos casos, assumido a posição de que a psicologia se tornou inviável e deve desaparecer. As referências objetivantes ou antropológicas, quando priorizadas pela psicologia, de fato não deixam saídas, tornando urgente o encontro com outros referenciais que possibilitem respirar novos ares. O pensamento de Kierkegaard e o de Foucault surgem como intercessores em face desse horizonte sombrio. Os dois filósofos se dedicaram a tornar o homem atento a si e ao mundo, priorizando saídas singulares e criativas em lugar da reprodução dos modos de ser hegemônicos que ameaçam igualar tudo e todos. Desnaturalizadores do presente e avessos às grandes especulações teóricas sobre a vida, escreveram obras que é preciso experienciar, mais do que simplesmente ler, a fim de captar-lhes a atmosfera e com elas operar. A partir dessa atitude, a psicologia experimental ou interpretativa pode dar lugar a uma psicologia experimentante, que acompanha o cotidiano ao invés de se colocar como uma curiosidade sem paixão. Tal psicologia segue de maneira interessada os movimentos da existência e a apropriação pessoal da verdade, que deixa de ser transcendente, metafísica ou sonhada, e aparece encarnada nas lutas, receios, enganos, ações e tensões do dia-a-dia dos sujeitos de carne, osso e espírito. É na tensão constituinte-constituído que o sujeito se forja, seja ele lançado por Deus, como pensa Kierkegaard, seja, como propõe Foucault, mergulhado nos esquemas e objetivações que toma como naturais: a tarefa do sujeito é tornar-se si mesmo, participando de forma mais livre da própria constituição, exercendo de maneira refletida e ética a liberdade e transparecendo a si mesmo, ao invés de tomar como suas as determinações que lhe são oferecidas. A presente tese visa, portanto, a estabelecer o diálogo entre Foucault e Kierkegaard, pelo viés da filosofia antiga, buscando inspiração para promover, no tempo presente, processos de subjetivação outros que os modos desesperados de ser, e práticas psicológicas mais experimentantes e menos disciplinadoras.

Genteel revolutionaries: the lives of Anna and Thomas Haslam

The lives of Thomas and Anna Haslam were dedicated to the attainment of women's equality. They were feminists before the word was coined. In an era when respectable women were not supposed to know of the existence of prostitutes, Anna became empowered to do the unthinkable, not only to speak in public but to discuss openly matters sexual and to attack the double standard of sexuality which was enshrined in the official treatment of prostitutes. Their life-long commitment to the cause of women's suffrage never faltered, despite the repeated discouragement of the fate of bills defeated in the House of Commons. The Haslams represented an Ireland which did not survive them. While they were dedicated to the union with Westminster, they worked happily with those who applied themselves to its destruction. Although in many ways they exemplified the virtues of their Quaker backgrounds, they did not subscribe to any organised religion. Despite living in straitened circumstances, they were part of an urban intellectual elite and participated in the social and cultural life of Dublin for over fifty years. It is tempting to speculate how the Haslams would have fared in post independence Ireland. Hanna Sheehy Skeffington who had impeccable nationalist credentials, was effectively marginalised. It is likely that they would have protested against discriminatory legislation in their usual law abiding manner but, in a country which quickly developed an overwhelmingly Roman Catholic ethos, would they have had a voice or a constituency? Ironically, Thomas's teaching on chastity would have found favour with the hierarchy; his message was disseminated in a simple and more pious manner in numerous Catholic Truth Society pamphlets. The Protestant minority never sought to subvert the institutions of the state, was careful not to criticise and kept its collective head down. Dáil Éireann was not bombarded with petitions for the restoration of divorce facilities or the unbanning of birth control. Those who sought such amenities obtained them quietly 'in another jurisdiction.' Fifty years were to pass before the condom wielding 'comely maidens' erupted on to the front pages of the Sunday papers. They were, one imagines, the spiritual descendants of the militant rather than the constitutional suffrage movement. "Once and for all we need to commit ourselves to the concept that women's rights are not factional or sectional privileges, bestowed on the few at the whim of the many. They are human rights. In a society in which the rights and potential of women are constrained no man can be truly free." These words spoken by Mary Robinson as President of Ireland are an echo of the principles to which the Haslams dedicated their lives and are, perhaps, a tribute to their efforts.

Synthesis and characterisation of novel superficially porous silica based stationary phases for use in liquid chromatography

The concept of pellicular particles was suggested by Horváth and Lipsky over fifty years ago. The reasoning behind the idea of these particles was to improve column efficiency by shortening the pathways analyte molecules can travel, therefore reducing the effect of the A and C terms. Several types of shell particles were successfully marketed around this time, however with the introduction of high quality fully porous silica under 10 μm, shell particles faded into the background. In recent years a new generation of core shell particles have become popular within the separation science community. These particles allow fast and efficient separations that can be carried out on conventional HPLC systems. Chapter 1 of this thesis introduces the chemistry of chromatographic stationary phases, with an emphasis on silica bonded phases, particularly focusing on the current state of technology in this area. The main focus is on superficially porous silica particles as a support material for liquid chromatography. A summary of the history and development of these particles over the past few decades is explored, along with current methods of synthesis of shell particles. While commercial shell particles have a rough outer surface, Chapter 2 focuses on the novel approach to growth of smooth surface superficially porous particles in a step-by-step manner. From the Stöber methodology to the seeded growth technique, and finally to the layer-bylayer growth of the porous shell. The superficially porous particles generated in this work have an overall diameter of 2.6 μm with a 350 nm porous shell; these silica particles were characterised using SEM, TEM and BET analysis. The uniform spherical nature of the particles along with their surface area, pore size and particle size distribution are examined in this chapter. I discovered that these smooth surface shell particles can be synthesised to give comparable surface area and pore size in comparison to commercial brands. Chapter 3 deals with the bonding of the particles prepared in Chapter 2 with C18 functionality; one with a narrow and one with a wide particle size distribution. This chapter examines the chromatographic and kinetic performance of these silica stationary phases, and compares them to a commercial superficially porous silica phase with a rough outer surface. I found that the particle size distribution does not seem to be the major contributor to the improvement in efficiency. The surface morphology of the particles appears to play an important role in the packing process of these particles and influences the Van Deemter effects. Chapter 4 focuses on the functionalisation of 2.6 μm smooth surface superficially porous particles with a variety of fluorinated and phenyl silanes. The same processes were carried out on 3.0 μm fully porous silica particles to provide a comparison. All phases were accessed using elemental analysis, thermogravimetric analysis, nitrogen sorption analysis and chromatographically evaluated using the Neue test. I observed comparable results for the 2.6 μm shell pentaflurophenyl propyl silica when compared to 3.0 μm fully porous silica. Chapter 5 moves towards nano-particles, with the synthesis of sub-1 μm superficially porous particles, their characterisation and use in chromatography. The particles prepared are 750 nm in total with a 100 nm shell. All reactions and testing carried out on these 750 nm core shell particles are also carried out on 1.5 μm fully porous particles in order to give a comparative result. The 750 nm core shell particles can be synthesised quickly and are very uniform. The main drawback in their use for HPLC is the system itself due to the backpressure experienced using sub – 1 μm particles. The synthesis of modified Stöber particles is also examined in this chapter with a range of non-porous silica and shell silica from 70 nm – 750 nm being tested for use on a Langmuir – Blodgett system. These smooth surface shell particles have only been in existence since 2009. The results displayed in this thesis demonstrate how much potential smooth surface shell particles have provided more in-depth optimisation is carried out. The results on packing studies reported in this thesis aims to be a starting point for a more sophisticated methodology, which in turn can lead to greater chromatographic improvements.

Overconfidence and confirmation bias: are future managers vulnerable?

Decision makers often use ‘rules of thumb’, or heuristics, to help them handling decision situations (Kahneman and Tversky, 1979b). Those cognitive shortcuts are taken by the brain to cope with complexity and time limitation of decisions, by reducing the burden of information processing (Hodgkinson et al, 1999; Newell and Simon, 1972). Although crucial for decision-making, heuristics come at the cost of occasionally sending us off course, that is, make us fall into judgment traps (Tversky and Kahneman, 1974). Over fifty years of psychological research has shown that heuristics can lead to systematic errors, or biases, in decision-making. This study focuses on two particularly impactful biases to decision-making – the overconfidence and confirmation biases. A specific group – top management school students and recent graduates - were subject to classic experiments to measure their level of susceptibility to those biases. This population is bound to take decision positions at companies, and eventually make decisions that will impact not only their companies but society at large. The results show that this population is strongly biased by overconfidence, but less so to the confirmation bias. No significant relationship between the level of susceptibility to the overconfidence and to the confirmation bias was found.

The not so generalized effects of nonreciprocal trade agreements

This dissertation uses an empirical gravity equation approach to study the relationship between nonreciprocal trade agreements (NRTAs) and members’ trade flows. Estimations relate bilateral imports to trade policy variables using a very comprehensive dataset with over fifty years of data. Results show that meager average trade effects exist only if members are excluded from the world trading system or if they are very poor. As trade flows between NRTA members are already rising before their creation, results also suggest a strong endogeneity concerning their formation. Moreover, estimations show that uncertainty and discretion tend to critically hinder NRTA’s performance. On the other hand, reciprocal trade agreements show the opposite pattern regardless of members’ income status.Encouraging developing countries’ openness to trade through reciprocal liberalization emerges consequently as a possible policy implication.

Nas sombras da família coelho: a dinâmica de uma dominação política

As one of the most important cities in the state of Pernambuco, Petrolina is settled in the Pernabucanian backwoods, a place that still holds its own traditions and manners. Petrolina s economy is mainly based on primary activities. It s politics is run by Family groups which preserve themselves and remain in power, using the clientelism, which could be said as a give and get practice. That means that the suffrage is a currency to exchange benefits. The present study analyses facts occurred in the political history of the Coelho s Family, which still dominates the local Politics. They persist as heirs of the old system of Coronelism that is maintaining their power structuring a political machine, which is able to make them unbeatable for over fifty years. Despite of a family internal division, it benefits all of them, directly or indirectly. Based on empirical observation, we set a brief historical of the Coelho s family facts, in order to demonstrate the range of their power through the ancestry, which is to say we ve described the local political labyrinths. Our metodological choices were driven by the comprehensive sociology, through the Weberian ideal types, in order to find the answers for the historical, social and political conformation of the facts, in consonance with the reality. According to that, we ve studied the Coelho s political trajectory from 1968 to 2012, considering the election periods. Commonplace: where a new generation becomes active subjects on a new apprenticeship, moral and intellectual. After all, they are all family heirs
