Purpose Emerging economies have to address positive challenges such as sustainability, digitalization, entrepreneurial readiness and planning and behavioral strategies and negative challenges, such as corruption and bureaucracy. The COVID-19 pandemic hit all economies and arguably made hotel businesses that are from less typical emerging economies, such as the Czech Small and medium-sized enterprises (SMEs), to deal with similar challenges to that of their counterparts from typical emerging economies. How do Czech hotel SMEs address the COVID-19 challenges and what sustainability message can be extracted from that with the relevance for not only businesses from emerging economies? The purpose of this paper is to explore how Czech hotel SMEs address the COVID-19 challenges and what sustainability. Design/methodology/approach A consolidated parsing of the literature, legislative and analytical framework, along with an investigative case study of 11 Czech hotel SMEs was performed, based on the questionnaire survey and semi-structured in-depth direct interviews. The holistic thematic analysis processed this fresh data and allowed Socratic questioning and glossing while addressing both research questions. Findings The performed case study reveals that typical challenges faced by entrepreneurs in emerging economies became, via COVID-19, universal challenges, these challenges are a valuable impulse for digitalization and changes of entrepreneurial strategies, but not so much for sustainability, and the omnipresent negative impact of corruption and bureaucracy. Originality/value This paper presents a pioneering study regarding the addressing COVID-19 and sustainability concerns by SMEs in a less typical emerging economy and offering a universal, partially comparative and sadly not so sustainable, message which is not just limited to emerging economies.

This paper provides a case study of a threatened seahorse species, Hippocampus reidi, highlighting the importance of using ecological information to assist conservation and management initiatives. Underwater visual sighting data (50 x 2m transect) gathered along the NE, SE and S portions of the Brazilian coast revealed an unequal distribution across localities, perhaps related to harvesting pressure, and a mean density of 0.026 ind.m-2. Our findings suggest some restricted spatial use by H. reidi, which was consistent with its estimated home range, and with re-sighting of specimens. Reproduction was recorded year-round, however productive peaks may exist. Components of habitat structure mostly used as anchoring points were mangrove plants, macroalgae, cnidarians, seagrass, sponges, and bryozoans. Conservation recommendations include: further characterization and mapping of habitats; assessment of availability and condition of microhabitats in selected areas, and studies on dispersal routes during initial life stages.

It is often important to estimate the abundance of a fish stock when the stock is somewhat depleted. For pelagic species this presents great operational difficulties, because adult surveys may be prohibitively expensive and time consuming. Here we introduce a method for estimating the spawning biomass of a stock by means of egg or larval surveys. In particular, we develop a series of models for presence-absence sampling of eggs or larvae and show how presence-absence data can be used to estimate adult spawning biomass. The models are based on an underlying probabilistic description of the aggregation of eggs or larvae, a search process, and a description of habitat structure. Methodologies are given for estimating the distribution of the size of the spawning biomass from presence-absence data. A case study of sardine is used to justify a number of the assumptions. The methods are applied to a 1985 survey for sardine eggs and are compared to an alternative method based on egg production.

Abstract This article presents an application of applied psychophysiological and cognitive and behavioral strategies to the treatment of sex offenders. The participants were 21 sex offenders treated as outpatients at the Veterans Administration Medical Center in White River Junction, Vermont. A repeated-case-study format was used. Because hyperventilation destabilizes the autonomic nervous system (disrupting and/or preventing erection and other aspects of male sexual arousal) and dramatically changes brain function (degrading train of thought and shifting neuroendocrine function), clients were taught to hyperventilate in response to thoughts and images of the targets of their illegal behavior. Psychophysiological indices included skin conductance and penile plethysmograph. Participants were treated in six individual sessions, and most have been followed up for more than 2 years. Results show that with motivated clients, this procedure produces convincing, positive results.

Cognitive-behavioral treatment (CBT) has rarely been applied as the primary treatment for the multiple, severe and persistent problems that characterize schizophrenia. This case study describes the process of CBT in the long-term outpatient care of a young woman with schizophrenia. The study highlights the adaptation of cognitive-behavioral strategies to the unique needs of schizophrenia and presents data regarding clinical outcomes in this case. Measures of psychosocial functioning, severity of symptoms, attainment of treatment goals and hospitalization data were used to assess change over the 3- year treatment period and at 1-year follow-up. Results indicate considerable improvement in all outcome variables and maintenance of treatment gains. These findings suggest the potential usefulness of cognitive-behavioral interventions in the treatment of schizophrenia.

Using an exemplar case study of an intervention completed in the sport of motocross, the authors attempt to demonstrate the advantages inherent in using integrated multidisciplinary approaches in the application of sport sciences to performance enhancement. The need for comprehensive, detailed, and well-planned interventions, which of necessity take time to both set up and implement, is also highlighted. In addition, the authors furnish examples of practical techniques that can be used to facilitate cognitive behavioral strategies in this type of sport. Implications for the preparation and training of applied sport psychology consultants are briefly discussed.

Telemedicine is an innovative approach that helps alleviate the health disparity in developing countries and improve health service accessibility, affordability, and quality. Few studies have focused on the social and organizational issues involved in telemedicine, despite in-depth studies of and significant improvements in these technologies. This paper used evolutionary game theory to analyze behavioral strategies and their dynamic evolution in the implementation and operation of telemedicine. Further, numerical simulation was carried out to develop management strategies for promoting telemedicine as a new way of delivering health services. The results showed that: (1) When the benefits are greater than the costs, the higher medical institutions (HMIs), primary medical institutions (PMIs), and patients positively promote telemedicine with benign interactions; (2) when the costs are greater than the benefits, the stability strategy of HMIs, PMIs, and patients is, respectively, ‘no efforts’, ‘no efforts’, and ‘non-acceptance’; and (3) promotion of telemedicine is influenced by the initial probability of the ‘HMI efforts’, ‘PMI efforts’, and ‘patients’ acceptance’ strategy chosen by the three stakeholders, telemedicine costs, and the reimbursement ratio of such costs. Based on theoretical analysis, in order to verify the theoretical model, this paper introduces the case study of a telemedicine system integrated with health resources at provincial, municipal, county, and township level in Guizhou. The findings of the case study were consistent with the theoretical analysis. Therefore, the central Chinese government and local governments should pay attention to the running cost of MIs and provide financial support when the costs are greater than the benefits. At the same time, the government should raise awareness of telemedicine and increase participation by all three stakeholders. Lastly, in order to promote telemedicine effectively, it is recommended that telemedicine services are incorporated within the scope of medical insurance and the optimal reimbursement ratio is used.
