This study presents an integrative approach to addressing the aggregate production problem. The solution suggested by the Linear Decision Rule (LDR) is used to generate the cash budget for a Portuguese mining firm. The generated budget is then compared to the real cash budget of the firm. The results of this study tend to underscore the need for integrating the production and finance subsystem of the firm when devising the production plan. Significant savings resulted from this approach.

The purpose of this paper is to analyse the causal relationships among the dimensions that explain consumer-based brand equity, and to determine the importance of each dimension in the assessment of overall brand equity.

A research instrument proposed by Yoo and Donthu was applied to undergraduate students of the University of Coimbra. Two leading brands in the Portuguese beer market were used in the study. Respondents were randomly assigned to one brand and were asked to rate all items on seven Likert-type scales. Based on Aaker’s conceptual framework, a structural equation model (SEM) was designed to analyse the proposed relationships.

A causal order between brand equity dimensions was established. The results suggest that the positive effects of perceived quality and brand awareness on overall brand equity are mediated by brand loyalty.

Although the exclusion of brand associations’ dimensions in the SEM improves the validity of the constructs, it should be regarded as a limitation, given its importance in brand equity building.

Marketing managers should focus on brand loyalty in order to increase overall brand equity, and should give special attention to perceived quality, since it is the factor with the strongest impact on brand loyalty.

The identification of the causal relations among brand equity dimensions and the analysis of their influence in overall brand equity, not yet clearly validated in the literature.

The purpose of this study is twofold. First, the relevant literature is reviewed briefly to provide a strategic context of the different views on strategy development. In the process, the linkages between the e-commerce view of strategy and previous views are explored. As such, the perspectives of different schools of thought on strategy are briefly highlighted. Second, the different dimensions of the e-commerce strategy and their impact on organizational performance are investigated.

A survey integrating different theoretical views of value creation was developed and sent to Portuguese e-commerce firms to assess the underlying dimensions of their strategies through factorial analysis. Then, a clustering analysis was performed to determine strategic groups to compare corporate performance.

Three e-commerce dimensions were identified: marketing, innovation and efficiency. Results of data analysis suggest that differentiation factors have impact on corporate performance in the context of virtual markets.

Although the Portuguese specific nature of the study could be seen as a limitation of the generalization of the findings, in the authors’ view, it is not truly a limitation because Portuguese executives face the same challenges that other countries counterparts, due to the universal application of e-commerce. Moreover, the use of a Portuguese sample validates findings from other cultural settings, contributing toward a unified theory and testing its applicability. In this way, it is an opportunity rather then a limitation.

The research identifies what is strategic and highlights the competitive methods that enhance differentiation in virtual markets, which could be useful as a framework for strategic formulation. Moreover, it provides a theoretical rational for investments in intangible assets.

The development of a survey to assess e-commerce strategies and the identification of the e-commerce strategic dimensions are the main contributions of this research, which highlights the importance of differentiation factors in virtual markets.

This study aims to explore demographic market segments’ effect on the relationships between memorable tourism experiences (MTEs), perceived value dimensions and tourists’ behavioral intentions.

The data were collected with an online survey that gathered information on MTEs, economic value, quality value, emotional value, social value and intentions to recommend and revisit. Based on a sample of 1,003 Portuguese tourists, the research model was estimated using partial least squares path modeling.

The results reveal that MTEs have a positive impact on all four perceived value dimensions. Emotional and social value have a positive effect on recommendation intentions. Tourists from different demographic segments exhibit heterogeneous patterns regarding perceived value dimensions’ influence on these individuals’ behavioral intentions. Emotional value has the strongest impact for females, but males are influenced more by social value. Economic value significantly contributes to younger tourists’ recommendation intention, while quality value has the same effect on the 36–45 age group.

This study extended the existing knowledge by confirming heterogeneity among different tourist segments defined by age and gender regarding the relationships between MTEs, perceived value dimensions and behavioral intentions.

本研究旨在探讨人口统计细分市场对难忘旅游体验 (MTE)、感知价值维度和游客行为意愿之间关系的影响。

数据通过在线调查收集。该调查收集了有关 MTE、经济价值、质量价值、情感价值、社会价值以及推荐和重访意愿的信息。研究模型根据 1,003 名葡萄牙游客的样本使用偏最小二乘路径模型进行分析验证。

分析结果表明, MTE 对所有四个感知价值维度都有积极影响。情感价值和社会价值对推荐意愿有正向影响。在游客的感知价值维度对他们行为意愿的影响方面, 不同人口统计背景的群体表现出不同的模式。情感价值对女性的行为意愿影响最大, 而社会价值对男性行为意愿影响最大。对于年轻群体, 经济价值影响其推荐意愿, 而对于 36–45 年龄组的群体, 则是质量价值影响其推荐意愿。

本研究证明按年龄和性别定义的不同旅游群体对于 MTE、感知价值维度和行为意愿之间关系的异质性, 从而扩展了现有文献。

Este estudio buscó explorar el efecto de los segmentos demográficos en la relación entre las experiencias turísticas memorables (MTE, por sus siglas en inglés memorable tourism experiences), las dimensiones del valor percibido y las intenciones de comportamiento de los turistas.

Los datos se recogieron mediante una encuesta online que recopiló información sobre MTEs, valor económico, valor de calidad, valor emocional, valor social, intención de recomendar y de revisita. El modelo de investigación se estimó en base a una muestra de 1.003 turistas portugueses aplicando la metodología de mínimos cuadrados parciales (PLS).

Los resultados revelan que las MTE tienen un impacto positivo en las cuatro dimensiones del valor percibido. El valor emocional y social tiene un efecto positivo en las intenciones de recomendación. Los turistas de diferentes segmentos demográficos exhiben patrones heterogéneos en cuanto a la influencia de las dimensiones del valor percibido en las intenciones de comportamiento. El valor emocional tiene el impacto más fuerte para las mujeres y el valor social para los hombres. El valor económico es relevante para explicar las intenciones de recomendación para el grupo más joven y el valor de calidad para el grupo de edad de 36 a 45 años.

Este estudio amplía el conocimiento existente al confirmar la heterogeneidad entre los diferentes segmentos turísticos definidos por edad y género con respecto a las relaciones entre los MTE, las dimensiones del valor percibido y las intenciones de comportamiento.

The purpose of this study is to understand challenges and constraints in reaching top leadership positions for women in the Portuguese press. Specifically, it aims at characterizing their communication and leadership styles, and at identifying main gender biases in newsrooms routines from their point of view.

A qualitative method was employed by conducting in-depth interviews with four women who have held higher management positions in Portuguese leading newspapers. Participants were asked to characterize their communication and leadership style, but also newsrooms environment, trying to understand how gender asymmetries persist and manifest. Results were analyzed using thematic analysis.

While considering that Portuguese newsrooms are no longer environments marked by a sexist/macho environment, through increasing female participation, women still represent a minority in leadership. Leadership traits linked to male styles, including assertiveness and courage, were revealed, though mixed with a more participative/relational leadership. Also, female leaders regret when emotional ties with teams are not developed and recognized some degree of privilege towards other women through family support or not having children.

There is a limited number of interviews, although they represent the few top women leaders in Portuguese journalism.

Policymaking recommendations derived from conclusions include participative leadership, implementing quotas, and monitoring tools of gender biases and special training.

Media literacy policies and open debates on main media outlets concerning female leadership and communication styles may contributes toward the acknowledgement of lingering gender biases in the industry.

This study contributes to a fuller insight into the identification of leadership and personal traits among women who managed to disrupt stigmas and break barriers. Their voices are seldom heard in studies focusing leadership, so results enable ascertaining whether there is a female way of leading in journalism and comprehending the sense of privilege these women perceive.

Excessive high caloric and nutritional intake has been associated with weight gain which is linked to an increased prevalence of cardiovascular disease, type 2 diabetes and several types of cancers. The purpose of this paper is to characterize the nutritional intake pattern of the population in terms of energy, macro and micronutrients.

There were assessed 513 workers of the University of Porto (UP) randomly selected. The Food Processor Plus was used to convert foods into nutrients and, to assess nutritional intake adequacy. Data were compared to Dietary Reference Intakes and with recommended ranges by the World Health Organization.

The intake of most individuals was above recommendations for protein, carbohydrates and sodium. The average of energy intake observed in UP employees was lower than data available for Portuguese general population. The protein, carbohydrates, total fat and water intake, cholesterol, saturated, monounsaturated, polyunsaturated fatty acids and sodium intake were found to be significantly higher for men. Significant differences were found for vitamin D and calcium between age ranges; Carbohydrates, sugar, monounsaturated fatty acids, cholesterol, water and vitamin K was significantly different between teachers and non-teachers.

According to nutritional intake analysis, food consumption of this population was unbalanced, attending to high protein, carbohydrates and sodium intake.
