Purpose The purpose of this paper is to investigate and develop an integrated theoretical relationship by including destination image and attitudes into the quality-value-satisfaction-loyalty paradigm in the context of beach tourism. Design/methodology/approach A personal-administered survey was conducted using a convenient sampling technique to collect data from 601 tourists who had visited popular beach destinations in Bangladesh. Then, the structural relationships between the factors likely to affect tourist attitudes and loyalty were examined. Findings The findings reveal that both service quality and perceived values have a direct effect on destination image, tourist attitudes and satisfaction. Additionally, destination image and satisfaction significantly affect tourist attitudes and loyalty. Research limitations/implications The direct relationship of perceived service quality and perceived value with tourist loyalty was ignored in the model due to reporting consecutive indirect relationship between them in prior studies. Practical implications These findings contribute to the extension of theoretical and managerial knowledge, especially in a beach tourism setting, where little research has been done to investigate the proposed relationships. Originality/value The originality of this study lies in providing theoretical and empirical evidence regarding the effect of service quality and perceived value, especially on destination image and tourist attitude to behaviour in the loyalty model, which has been scarcely examined in the prior tourism literature.

Sulfur‐containing scaffolds play a significant role in many important biological processes. The thiazole‐2‐imine derivatives have gained significant biological attention due to their interesting pharmacological activities and act as potential therapeutic agents. Many of their syntheses suffer from the drawbacks such as the handling of toxic reagents, harsh reaction conditions, longer reaction times and tedious separation procedures. To their easy access, we applied first time flow electrochemical approach under free supporting electrolytes conditions and without the use of expensive catalysts and reagents. This is not only the first electrochemical cyclization to access thiazolidin‐2‐imines also represents the first intramolecular sulfurization of unfunctionalized terminal alkenes. This flow electrolysis of N‐allylic thioureas generates radical intermediates of nitrogen and sulfur that cyclized via oxysulfurization of terminal alkenes and gives thiazolidin‐2‐imines with good to high yields under mild, green and environmentally friendly conditions.

Acetone semicarbazone (a Schiff base) has been synthesized and characterized. Its antineoplastic activity has been studied against Ehrlich ascites carcinoma (EAC) cells in Swiss albino mice by monitoring parameters like tumor weight, survival time, tumor cell growth inhibition and haematological characteristics. It was found that the compound at dose 2.0 mg/kg/day i.p (intra peritoneal) significantly decreases tumor weight, increases life span and reduces tumor cell growth rate in comparison to those of EAC bearing mice. The compound also alters the depleted haematological parameters like red blood cells (RBC), white blood cells (WBC), haemoglobin (Hb) % and differential counts (i.e. lymphocytes, neutrophils, monocytes) of EAC bearing mice towards normal. The compound enhances the number of macrophages in normal mice. The toxic effects of the compound on the host are not very high and the host recovers gradually towards normal within a few days after treatment. The compound can therefore be considered as a new potent antitumor agent. The efficiency is more or less comparable to that of a standard drug like bleomycin (0.3 mg/kg/day, i.p.).
