The objective of this paper is to assess the potential of Portuguese manufacturing firms with respect to two fundamental issues that have been at the core of important debates about comparative advantages of small firms and large ones: (1) Employment: Using a database compiled between 1982 and 1992, we analyse the contribution of small firms to job creation. This analysis aims to consider the different aspects of firm mobility: Entry, expansion, contraction and exit. The results indicate that, in the period considered, only small firms created employment and that this creation is mainly associated with the expansion of young firms located in the Littoral North and Centre regions of Portugal. Nevertheless, when we consider only small firms that are incumbents in all the period, results indicate that job creation is a feature specific to a small number of fast‐growing small firms. The effects of the economic cycle were tested too, and it was found that employment creation by small firms is less sensitive to economic fluctuations, as reductions in employment in small firms do not seem to grow in crisis periods. (2) Technical efficiency: Independently from the job creation potential, it is important to evaluate whether small firms use economic resources in an efficient manner. To assess the efficiency of small businesses relative to large ones, we use plant‐level information, thereby specifying and estimating a translog production model. This model allows estimating and comparing returns of scale and substituting elasticities for both small and large production units, covering a large number of six‐digit sectors for the year 1995. Preliminary results suggest that: (I) There are significant differences in the production technology between large and small establishments; (ii) small establishments do not appear to be more flexible than large ones in factor substitution; (iii) large size is not a condition for efficiency in production. Therefore, considering the importance and weight small firms have upon the manufacturing industry employment volume, and the lack of any evidence regarding technical inefficiencies in the production, we may infer that small firms justify the public powers’ attention, while designing and implementing policies which would support their survival as well as their growth. Such policies should enhance and refine their labour (and management) qualification techniques as well as design better strategies for disseminating information and new technologies. In fact, these policies would most certainly promote the development of Portuguese small firms, turning them into more innovating, flexible and competitive ones, even in those industries which traditionally comprise large firms.

The literature review reveals that lake tourism and lake-destination areas (LDA) have been particularly absent from destination image (DI) studies over 45 years of research. In fact, there is a lack of research concerning the characteristics of lake tourism, particularly related to the attributes involved in the formation of lake-DI. Therefore, this paper aims to explore lake tourism and lake-DI based on the Alqueva Lake more thoroughly, it being the biggest man-made lake in Europe, as an emerging lake-destination area located in the south of Portugal.

Within this, the perceptions of stakeholders professionally involved with this type of destination were examined through 17 semi-structured interviews based on content-analysis as a qualitative technique. Framed by the important contribution of visual-based research in tourism studies, this study adopts two approaches: an attribute-based approach (textual data) and a photo-based approach (visual data), to strengthen the concept, characteristics and dimensions of lake tourism and image attributes applied to this type of destinations. Multiple techniques of extracting data were used, demonstrating the importance of using various techniques in obtaining image attributes as a first step in assessing DIs.

The findings revealed textual and pictorial attributes related to lake tourism and LDA, which confirms that although image attributes are universally important, depicting specific attributes is important considering particular types of tourism, such as lake tourism.

This is a very recent sub-field of DI studies, which justifies its investigation on a theoretical as well as on a practical management level.

Lake tourism is a growing academic sub-field of tourism studies with an emerging body of literature. However, little research attention has been given to lake-destinations’ projected or perceived tourism images. Specifically, there has been a scarcity of literature investigating the variables involved in the formation of a lake-destination image. Therefore, this study aims to explore the main attributes that might potentially influence this type of destination, and simultaneously, contribute to conceptualizing and defining lake tourism as recent research area. An explorative study was then conducted in order to generate a set of image variables through the use of textual and photographic data. The results will contribute to characterize potential lake-destinations and to develop a final list of variables specifically related to this type of destination.

Surfactants have been reported to have high inhibition efficiencies for corrosion of steel. This paper aims to study the performance of a low toxic copolymer of polydimethylsiloxane and polyoxyalkylene (POA) surfactant named as POPS, as a corrosion inhibitor for mild steel (ASTM 1005) in hydrochloric acid (HCl) solution at 25°C.

To evaluate POPS efficiency as a corrosion inhibitor, the following techniques were used: surface tension measurements, weight loss measurements, open circuit potential monitoring, potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS), scanning electron microscopy and contact angle measurements.

Results indicated that POPS acted as a mixed corrosion inhibitor and led to a hydrophobic protector film on the metal surface. The adsorption process obeyed the Langmuir adsorption isotherm by chemisorption. The maximum efficiency of the surfactant studied was achieved in a concentration around the critical micelle concentration.

Surfactant (POPS) of low level of toxicity acts as a mixed corrosion inhibitor in HCl medium. Inhibitor film formation was characterized by EIS results. A mechanism for corrosion inhibition is proposed.

Listening to and considering children's voices shows respectful regard for children's needs, interests and experiences, and helps discern what is meaningful for them in a particular subject or situation. Creating opportunities for the expression of children's voices implies child-centred practice: recognising children as active agents, with evolving competences and capacity to understand, think and choose with some degree of autonomy, thus being able to influence decision-making. Therefore, the commitment to listen to children's voices represents a fundamental step towards empowering children and supporting their participation rights. Importantly, children have the right to be heard and to have their voices considered from the earliest ages, in their significant relational contexts, such as early childhood education and care (ECEC). Listening to and valuing children's multiple voices in ECEC can be done in many ways, ensuring the context, children's background, characteristics and preferences are respected. In this chapter, we address the specificities of listening to children's voices and taking them into account in ECEC. We discuss common challenges that may prevent the full expression and consideration of children's voices, and ways to overcome them, to ensure children's meaningful participation in what matters to them and support them in becoming active citizens in society.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

This study examines the efficiency dynamics of public health service providers in Colombia between 2010 and 2021. In order to achieve this objective, a data panel is utilized to assess the effectiveness of 841 institutions across three levels of complexity (1, 2 and 3) in providing patient care, taking into account user satisfaction from 2010 to 2021.

By employing growth mixture analysis (GMA) and other statistical techniques, we may identify unique efficiency profiles among hospitals with different levels of complexity.

The results demonstrate varied efficiency patterns, with certain profiles generally retaining or improving efficiency over time, while others observe fluctuations or reductions. Efficiency outcomes are significantly impacted by factors such as capital investment, operational costs and workforce mix. Efficiency levels can be improved by making strategic investments in capital infrastructure and implementing effective operational cost management.

Changes in the healthcare market conditions in recent years in Colombia have compelled healthcare providers (IPS) to transform themselves into sustainable organizations.

This paper aims to estimate the price premium for a sea view on room rent in a Nordic context, i.e. where proximity to the sea is not valued for the presence of swimmable beaches and suntanning activities. The analysis also explores regional and seasonal variations in price premiums.

To do so, the study uses information from a Web search of room rents during winter and summer peak seasons. The investigation is based on hotels located along the St. Lawrence River in the Province of Quebec (Canada), where about 40 to 60 km separate both shores. A matching procedure and hedonic pricing models are used to identify the causal impact of a sea view on individual room rents.

Results suggest that the view price premium varies between 0% and 20%. It is relatively stable on the North Shore, but varies highly on the South Shore, where touristic activities are mainly operating in summertime. The estimation suggests a median local economic benefit of about $30.1M/year.

The analysis reveals that a hedonic pricing model might fail to identify causal effects, especially if it does not account for hotel characteristics. A multiple linear regression model does not ensure a causal interpretation if it neglects unobserved characteristics correlated with the view.

The paper proposes a matching identification procedure accounting for spatial confounding to retrieve the causal impact of the view of the sea on hotel room rents. A heterogeneity analysis suggests that view price premium on room rent can vary within seasons but mainly across regions, even for the same amenities.
