This paper examines how socio-emotional factors can influence family firms' commitment to entrepreneurially-oriented activities, and how their level of commitment is moderated by the technological intensity of the sector and firm performance. We find that, while family firms are less entrepreneurially-oriented than nonfamily firms, this gap closes with increasing technological intensity of the sector. We find no evidence, however, to suggest any change in entrepreneurial orientation in family firms resulting from a drop in firm performance.
This article analyses the connection between the use of advanced human resource management (HRM) practices, individually and as a system, with manufacturing flexibility. The results show a positive relationship between the implementation of advanced HRM practices and manufacturing flexibility. While most of the advanced HRM practices analysed show higher levels of implementation in flexible firms, no differences are observed in training efforts. Flexible firms are more prone to implement systems of advanced HRM practices.
BackgroundIn plants, nitrate (NO3-) nutrition gives rise to a natural N isotopic signature (δ15N), which correlates with the δ15N of the N source. However, little is known about the relationship between the δ15N of the N source and the 14N/15N fractionation in plants under ammonium (NH4+) nutrition. When NH4+ is the major N source, the two forms, NH4+ and NH3, are present in the nutrient solution. There is a 1.025 thermodynamic isotope effect between NH3 (g) and NH4+ (aq) which drives to a different δ15N. Nine plant species with different NH4+-sensitivities were cultured hydroponically with NO3- or NH4+ as the sole N sources, and plant growth and δ15N were determined. Short-term NH4+/NH3 uptake experiments at pH 6.0 and 9.0 (which favours NH3 form) were carried out in order to support and substantiate our hypothesis. N source fractionation throughout the whole plant was interpreted on the basis of the relative transport of NH4+ and NH3.ResultsSeveral NO3--fed plants were consistently enriched in 15N, whereas plants under NH4+ nutrition were depleted of 15N. It was shown that more sensitive plants to NH4+ toxicity were the most depleted in 15N. In parallel, N-deficient pea and spinach plants fed with 15NH4+ showed an increased level of NH3 uptake at alkaline pH that was related to the 15N depletion of the plant. Tolerant to NH4+ pea plants or sensitive spinach plants showed similar trend on 15N depletion while slight differences in the time kinetics were observed during the initial stages. The use of RbNO3 as control discarded that the differences observed arise from pH detrimental effects.ConclusionsThis article proposes that the negative values of δ15N in NH4+-fed plants are originated from NH3 uptake by plants. Moreover, this depletion of the heavier N isotope is proportional to the NH4+/NH3 toxicity in plants species. Therefore, we hypothesise that the low affinity transport system for NH4+ may have two components: one that transports N in the molecular form and is associated with fractionation and another that transports N in the ionic form and is not associated with fractionation.
Purpose A great deal of research has examined the relationship between a single CEO attribute and a single measure of firm performance; no attempts have been made to integrate them to create a more global vision of both. Therefore, trying to answer new calls from Wang et al. (2016) or Liu, Fisher and Chen (2018) about a more global vision of the CEO characteristics, the authors are going to take a step forward to combine different CEO characteristics with different firm performance measure in order to show that a certain managerial profile would have an impact on several variables of firm performance. This paper aims to discuss these issues. Design/methodology/approach Using a sample of 1,236 small firms in high- and medium-high-technology sectors and through the Canonical Correlation Analysis, the authors are able to create different CEO’s profiles that influence on different combinations of firm performance variables. Findings The authors obtain different CEO’s profiles that influence on different combinations of firm performance variables. Each CEO profile will enhance or diminish one kind of performance measure. The authors found that on the one hand, young, well-educated with external experience CEO profile will enhance innovative performance and firm growth, and on the other hand, old and more internal and external experience CEO profile will enhance the exploitation of external knowledge. Originality/value Through this analysis, the authors will be able to provide a more comprehensive analysis of the predictions about the role of CEOs in small firms.
The natural 15N/14N isotope composition (δ15N) of a tissue is a consequence of its N source and N physiological mechanisms in response to the environment. It could potentially be used as a tracer of N metabolism in plants under changing environmental conditions, where primary N metabolism may be complex, and losses and gains of N fluctuate over time. In order to test the utility of δ15N as an indicator of plant N status in N2-fixing plants grown under various environmental conditions, alfalfa (Medicago sativa L.) plants were subjected to distinct conditions of [CO2] (400 vs. 700 μmol mol−1), temperature (ambient vs. ambient +4°C) and water availability (fully watered vs. water deficiency—WD). As expected, increased [CO2] and temperature stimulated photosynthetic rates and plant growth, whereas these parameters were negatively affected by WD. The determination of δ15N in leaves, stems, roots, and nodules showed that leaves were the most representative organs of the plant response to increased [CO2] and WD. Depletion of heavier N isotopes in plants grown under higher [CO2] and WD conditions reflected decreased transpiration rates, but could also be related to a higher N demand in leaves, as suggested by the decreased leaf N and total soluble protein (TSP) contents detected at 700 μmol mol−1 [CO2] and WD conditions. In summary, leaf δ15N provides relevant information integrating parameters which condition plant responsiveness (e.g., photosynthesis, TSP, N demand, and water transpiration) to environmental conditions.
Purpose The purpose of this paper is to explore the possible causes of the heterogeneous productivity observed in Spanish firms, finding evidence of a link between managerial capability and higher productivity in the context of family firms. Also, innovative human resource policies are much more frequently found in companies where there is a high level of management capability. Design/methodology/approach Productivity differences in Spanish family firms are, for the first time, analysed from a managerial view, and using multiple correspondence analysis (MCA). Findings This paper proposes a way to measure managerial capability. Innovative human resource policies are much more frequently found in companies with high levels of management capability. The authors show that sustained competitive advantage is not just a function of single or isolated components, but rather a combination of human capital elements. Besides, a clear association between high managerial capability and performance in family firms is established. Thus, better management skills enable Spanish family firms to design the necessary strategies and internal structures to facilitate their adjustment to the business environment, and, thereby, achieve operational performance gains. Originality/value This paper proposes a way to measure managerial capability and its association with productivity in Spanish family firms using MCA. The authors also show a clear positive association between high managerial capability and performance in family firms. Thus, better management skills enable Spanish family firms to achieve operational performance gains.
In this article, we present a methodology to assess the risk incurred by a participant in an activity involving danger of injury. The lack of high-quality historical data for the case considered prevented us from constructing a sufficiently detailed statistical model. It was therefore decided to generate a risk assessment model based on expert judgment. The methodology is illustrated in a real case context: the assessment of risk to participants in a San Fermin bull-run in Pamplona (Spain). The members of the panel of "experts on the bull-run" represented very different perspectives on the phenomenon: runners, surgeons and other health care personnel, journalists, civil defense workers, security staff, organizers, herdsmen, authors of books on the bull-run, etc. We consulted 55 experts. Our methodology includes the design of a survey instrument to elicit the experts' views and the statistical and mathematical procedures used to aggregate their subjective opinions.
This paper uses survey data on 965 Spanish manufacturing firms to examine the implementation of innovative management practices and the relationship of this with the organization of work and human resource management. The paper takes into account transformations in technology, quality management and the organization of work. Using cluster analysis, we identify the different paths that firms are following in order to improve their performance, finding that simultaneous transformations in several dimensions lead to greater success than partial transformation, or none at all.
