Maintenance and destrcution of R&D leadership

In the standard Schumpeterian-growth models only follower firms invest in R&D activities and larger economies grow faster. Since these results are counterfactual, this paper reveals that leader firms often support R&D activities and economic growth can be independent of the market size. In particular, the maintenance of R&D leadership increases with: (i) the technological-knowledge gap between leader and followers, since a firm-specific learning effect of accumulated technological knowledge from past R&D is considered, (ii) the leaders’ strategies that delay the next successful R&D supported by some follower firm, (iii) the market size, and (iv) the up-grade of each innovation.

Supporting leadership development by exposure to role models: two case studies

The idiomatic expression “In Rome be a Roman” can be applied to leadership training and development as well. Leaders who can act as role models inspire other future leaders in their behaviour, attitudes and ways of thinking. Based on two examples of current leaders in the fields of Politics and Public Administration, I support the idea that exposure to role models during their training was decisive for their career paths and current activities as prominent characters in their profession. Issues such as how students should be prepared for community or national leadership as well as cross-cultural engagement are raised here. The hypothesis of transculturalism and cross-cultural commitment as a factor of leadership is presented. Based on current literature on Leadership as well as the presented case studies, I expect to raise a debate focusing on strategies for improving leaders’ training in their cross-cultural awareness.

Flexibility in a Stackelberg leadership with differentiated goods

We study the effects of product differentiation in a Stackelberg model with demand uncertainty for the first mover. We do an ex-ante and ex-post analysis of the profits of the leader and of the follower firms in terms of product differentiation and of the demand uncertainty. We show that even with small uncertainty about the demand, the follower firm can achieve greater profits than the leader, if their products are sufficiently differentiated. We also compute the probability of the second firm having higher profit than the leading firm, subsequently showing the advantages and disadvantages of being either the leader or the follower firm.

Formative assessment and motivation in higher education: a successful approach in mechanical engineer thermodynamics

Between 2000/01 and 2006/07, the approval rate of a Thermodynamics course in a Mechanical Engineer graduation was 25%. However, a careful analysis of the results showed that 41% of the students chosen not to attend or dropped out, missing the final examination. Thus, a continuous assessment methodology was developed, whose purpose was to reduce drop out, motivating students to attend this course, believing that what was observed was due, not to the incapacity to pass, but to the anticipation of the inevitability of failure by the students. If, on one hand, motivation is defined as a broad construct pertaining to the conditions and processes that account for the arousal, direction, magnitude, and maintenance of effort, on the other hand, assessment is one of the most powerful tools to change the will that students have to learn, motivating them to learn in a quicker and permanent way. Some of the practices that were implemented, included: promoting learning goal orientation rather than performance goal orientation; cultivating intrinsic interest in the subject and put less emphasis on grades but make grading criteria explicit; emphasizing teaching approaches that encourage collaboration among students and cater for a range of teaching styles; explaining the reasons for, and the implications of, tests; providing feedback to students about their performance in a form that is non-egoinvolving and non-judgemental and helping students to interpret it; broadening the range of information used in assessing the attainment of individual students. The continuous assessment methodology developed was applied in 2007/08 and 2008/09, having found an increase in the approval from 25% to 55% (30%), accompanied by a decrease of the drop out from 41% to 23,5% (17,5%). Flunking with a numerical grade lowered from 34,4% to 22,0% (12,4%). The perception by the students of the continuous assessment relevance was evaluated with a questionnaire. 70% of the students that failed the course respond that, nevertheless, didn’t repent having done the continuous assessment.

Simultaneous decisions or leadership in an international competition

In this paper, we study an international market with demand uncertainty. The model has two stages. In the first stage, the home government chooses an import tariff to maximize the revenue. Then, the firms engage in a Cournot or in a Stackelberg competition. The uncertainty is resolved between the decisions made by the home government and by the firms. We compare the results obtained in the three different ways of moving on the decision make of the firms.

Linking transformational leadership and organisation commitment

The main goal of this paper is to analyse the impacts of transformational leadership on organisational commitment. To this effect we developed a case study following a quantitative methodological approach. The research was conducted at the Serralves Foundation (Porto, Portugal) to empirically test the proposed research model and its hypothesis. The empirical results confirm that transformational leadership are not significantly influenced by commitment. As the main limitation of this study we highlight the fact that it does not consider the leaders’ perspective on their subordinates’ behaviour.

Liderança e motivação nas entidades responsáveis pela recolha e gestão de resíduos do concelho da Maia

O contexto, o tempo é de mudança. Ainda que o não fosse, falar de gestão de recursos humanos, falar de pessoas, é falar em mudança (ou mudanças). A economia mundial é que dita o presente e o futuro das organizações, privadas ou públicas, com ou sem fins lucrativos, pequenas, médias e grandes. Quando, em 2011, foi chumbado o quarto projeto do Programa de Estabilidade e Crescimento, vivia-se em Portugal um período crítico, ao qual não era alheia a conjuntura internacional de recessão económica. No domínio da Administração Pública, procurava-se redesenhar as organizações, imprimir-lhes uma gestão mais privatística, de otimização de recursos e controlo de custos. Hoje, sabe-se que aquela rejeição do programa político governamental teria outras consequências, as que atualmente os portugueses vêm sentindo. É um período de mudanças radicais, sem precedentes. Como lideram ou como administram os responsáveis pelas organizações, no contexto atual? Quais as qualidades de liderança que imperam em situações de crise e de austeridade? Como reagem líderes e liderados em períodos de recessão ou adversidade? E, sobretudo, como falham uns e são bem-sucedidos outros? Desde logo, há que reconhecer a importância e valorizar o capital humano: atrair, reter e desenvolver. Neste trabalho, procuramos responder aos crescentes interesse e preocupação em redesenhar, reformar e melhorar a gestão na administração pública. Daí o interesse pela motivação e a sua relação com o estilo de liderança adotado nas organizações deste setor, fator determinante para o comprometimento, a eficácia e a produtividade no trabalho. Mais concretamente, o objetivo deste estudo é compreender a relação entre o sistema de gestão que predomina nas entidades responsáveis pela recolha e gestão de resíduos do concelho da Maia e a motivação dos seus colaboradores, assim como a satisfação dos mesmos com a sua chefia. A metodologia de investigação utilizada orienta-se para a abordagem quantitativa, recorrendo-se a técnicas e instrumentos de natureza quantitativa, tais como o questionário de escala de resposta tipo Likert, por considerarmos ser a mais ajustada às pretensões desta investigação.

Stackelberg leadership with demand uncertainty in a differentiated duopoly

On a symmetric differentiated Stackelberg duopoly model in which there is asymmetric demand information owned by leading and follower firms, we show that the leading firm does not necessarily have advantage over the following one. The reason for this is that the second mover can adjust its output level after observing the realized demand, while the first mover chooses its output level only with the knowledge of demand distribution.

Flexibility and leadership advantages in a model with uncertain demand

We consider a differentiated Stackelberg model with demand uncertainty only for the first mover. We study the advantages of flexibility over leadership as the degree of the differentiation of the goods changes.

Flexibility in Stackelberg leadership

We consider a Stackelberg model with demand uncertainty, only for the first mover. We study the advantages of leadership and flexibility with the variation of the demand uncertainty. Liu proved for demand uncertainty parameter greater than three that the follower firm can have an advantage with respect to the leading firm for some realizations of the demand intercept. Here, we prove that for demand uncertainty parameter less than three the leading firm is always in advantage.
