Salinity is the main environmental factor responsible for limited plant growth in many areas of the world. Gleditsia sinensis Lam. is a shelter forest tree species that does not require high-quality soil and can even grow in mild saline soil. This study mainly explored the tolerance of G. sinensis to salt and the effect of exogenous calcium addition on the growth of G. sinensis in a salinized soil. The concentrations of NaCl were set as 0 mmol/L, 100 mmol/L, and 200 mmol/L. Compared with the control, under the NaCl treatment of 200 mmol/L, it was observed that the leaves of G. sinensis turned yellow, the electrical conductivity significantly increased, and the water content and the chlorophyll content significantly decreased, which is probably unfavorable for growth. Our study showed that the addition of 10 mmol/L exogenous calcium chloride under salt stress had a positive effect on the growth and photosynthetic characteristics of G. sinensis. Moreover, the addition of exogenous calcium attenuated the cytotoxicity caused by Na+ under salt stress and promoted the equilibrium of ion homeostasis. More importantly, the addition of exogenous calcium ions was beneficial for the survival of G. sinensis plants on salinized land and the increase of effective active ingredient content including phenolic compounds, which is of direct significance for improving environmental problems such as desertification of saline-alkali land. In conclusion, we investigated the effect of salt treatment on G. sinensis, as well as the positive effects of exogenous calcium on the survival and growth of G. sinensis in salt environment, which provided a scientific basis for the targeted cultivation of G. sinensis in salinized land and the effective utilization of salinized and alkaline land.

Special Case

Digitalization is a megatrend, but there is relatively little knowledge about its consequences for service work in general and specifically in knowledge-intensive business services (KIBS). We studied the impact of digitalization on psychological consequences for employees in tax consultancies as a special case of KIBS. We compare two tax consulting jobs with very different job demands, those of tax consultants (TCs) and assistant tax consultants (ATCs). The results show that the extent of digitalization at the workplace level for ATCs correlates significantly positively with their job satisfaction. For TCs, the same variable correlates positively with their work engagement. These positive effects of digitalization are mediated in the case of ATCs by the impact on important job characteristics. In the case of TCs, which already have very good working conditions, the impact is mediated by the positive effect on self-efficacy. Theoretical and practical consequences of these results are discussed.

In today’s increasingly competitive coffee industry, the point of running a good coffee shop is no longer to run a coffee and beverage shop simply, but to focus on the quality of service and the value that customers feel as a result. Previous studies have mainly discussed the customer satisfaction and behavioral intention of restaurants, while few studies have explored the influencing factors of customer satisfaction and behavioral intention of chain coffee shops. Given that the perceived service quality theory and DINESERV model can effectively predict customer satisfaction and behavioral intention, this study took 385 consumers in the first Starbucks Reserve flagship store in China as survey objects. SmartPLS 3.0 software was used to explore the relationship among respondents’ perceived service quality, customer perceived value, satisfaction, and behavioral intention. The results show that service quality has a partially significant positive effect on perceived value. Perceived service quality and customers’ perceived value both have significant positive effects on satisfaction. Customers’ satisfaction has a significant positive effect on their behavioral intention. These results indicate that enterprises should strengthen the emotional bond between consumers and enterprises and improve the reliability, assurance, and empathy of perceived service quality to create a better emotional resonance between consumers and the Starbucks brand to improve customer satisfaction. At the same time, it should also promote the symbolic perceived value of Chinese consumers to Starbucks to realize the sustainable development of coffee-shop operation and consumer repurchase. This study expands the research on the service quality, perceived value, and behavioral intention of coffee chain enterprises in the context of non-habitual coffee-drinking countries. Moreover, it provides case support for the operation and research of regional cultural consumption habits of international catering chain enterprises.

The present investigation aims study the sustainability of the business model of the Portuguese SMEs operating in the B2B International market analyzing the influence of dynamic marketing capabilities and adaptive marketing capabilities in their international marketing performance. It will also analyze the moderating effects of Competitive Intensity within this international scenario. A quantitative study was developed, using a questionnaire as a research method. In total, 335 valid responses were collected from Portuguese SMEs in June 2020. To test the hypotheses, multiple hierarchical regressions were performed. As for the analyzes involving Competitive Intensity environments, namely low and high intensity, dummies were developed to evaluate the different effects produced by the capacities in the International Marketing Performance. This study shows the positive impact of the dynamic marketing capabilities and adaptive marketing capabilities on the international marketing performance of the surveyed companies, essentially from the product development management, supply chain management, vigilant market learning and open marketing. when in a low competitive intensity environment only dynamic marketing capabilities had a positive effect on performance, but in a high, competitive, intensity environment both dynamic marketing capabilities and adaptive marketing capabilities showed positive effects in relation to performance. This study innovates by bringing international marketing, through two marketing capacities, from the perspective of SMEs that perform B2B activities.

Over Time

Development of calves depends on prenatal and postnatal conditions. Primiparous cows were still maturing during pregnancy, which can lead to negative intrauterine conditions and affect the calf’s metabolism. It is hypothesized that weaning calves at higher maturity has positive effects due to reduced metabolic stress. We aimed to evaluate effects of mothers’ parity and calves’ weaning age on growth performance and blood metabolites. Fifty-nine female Holstein calves (38.8 ± 5.3 kg birth weight, about 8 days old) were used in a 2 × 2 factorial experiment with factors weaning age (7 vs. 17 weeks) and parity of mother (primiparous vs. multiparous cows). Calves were randomly assigned one of these four groups. Live weight, live weight gain and morphometry increased over time and were greater in calves weaned later. Metabolic indicators except total protein were interactively affected by time and weaning age. Leptin remained low in early-weaned calves born to primiparous cows, while it increased in the other groups. The results suggest that weaning more mature calves has a positive effect on body growth, and calves born to primiparous cows particularly benefit from this weaning regimen. It also enables a smooth transition from liquid to solid feed, which might reduce the associated stress of weaning.

This paper contributes to the literature on innovation brokerage by analysing the effects of brokerage activities on the innovation and growth of small and medium-sized enterprises (SMEs). The authors provide a detailed description of the Technology Transfer Service (TTS), credited as a European best-practice innovation broker, at Area Science Park in Italy. They then carry out an exploratory econometric analysis, the results of which show that the support provided by the TTS enables research–industry collaboration and has positive effects on product and process innovation in SMEs, but it appears not to affect the generation of new patents in SMEs. The results also suggest that the growth in innovation enabled by the support of TTS has a positive effect on the SMEs' revenue growth and job creation. However the innovation broker is more effective in relation to larger firms than it is for micro-enterprises.

Intestinal Microbiocenosis

The recent scientific researches provide evidence of the important role of microbiota for human health. The microbiome is a very complex system, that exists in an equilibrium state and performs multiple functions. The intestinal microflora is disturbed under the influence of iatrogenic factors, and products of microbial origin are used to correct this. The first group of such drugs include probiotics. Their positive effect is associated with immunological and non‑immunological effects. The results of many studies proved the positive effects of probiotics in clinical practice, however publications of recent years outline their low effectiveness and transient nature of the effect, even with prolonged use. Another group of preparations refers to prebiotics, which selectively stimulate the growth of colon microflora. A combination of probiotics and prebiotics, called synbiotics, also in use. Currently, much attention is paid to metabiotics. This group includes various low molecular weight molecules with various chemical manifestations. The components of metabiotics are cellular elements, metabolites and signaling molecules of probiotic cultures. Metabiotics provide the optimal conditions of homeostasis in the contact zone, which are necessary for the normal interaction of the epithelium and microflora, as well as directly affect the physiological functions and biochemical reactions of the macroorganism. The antibacterial properties of metabiotics allow to fight pathogenic and opportunistic flora, without affecting the beneficial microorganisms of the intestine. Creation of targeted metabiotics is a novel promising direction in this area. The possibility of creating a programmed metabiotic drug is considered, depending on the type of disorders of the intestinal microbiocenosis and the peculiarities of the life of specific pathogenic or opportunistic strains.
