    Get PDF
    This study aimed to examine consumers’ willingness to pay a premium price for several environmental attributes of organic tomato to increase both producer production and consumer health in Palestine. The paper adopts the choice experiment method using the econometric analysis of the random utility model. The research questions of this study focus on awareness of the importance of ensuring / securing the environment, how many households in the West Bank purchase organic tomatoes, reasons for which households may be willing or not willing to pay more for organic tomatoes, and the main socio-economic variables that affect the households willingness to pay for organic tomatoes when making organic tomatoes choices. The empirical results show that organic tomatoes are preferred to conventional ones because of health claims by respondents so that we conclude that respondents are willing to pay more for organic tomatoes compared to conventional ones. Additionally, consumers prefer organic products because of health and environmental benefits. Some policy measures might further promote the consumption of organic products. These include creating awareness of the relevance of consuming organic products through effective marketing and educational campaigns. However, there are about 500 organic farms in Palestine with a total area of 1’0000 square meters mainly under fruit, almond, olives and dates. According to the Palestinian Agricultural Relief Committee, organic pasturelands are not found because of the Israeli control (German Development Agency GTZ) and according to the ministry of agriculture in Palestine, there are 24 organic olive farms with a total area of 18885 square meters

    The purpose of the present study is to investigate the role of human resource management (HRM) in the growth of startups. Accordingly, the missions and practices of HRM in startups are identified from the perspective of entrepreneurs and employees. A multiple case study approach is used by focusing on two startups in Iran. Moreover, the data are collected by interviewing one entrepreneur and four employees in each company. Besides, qualitative data are analysed using thematic analysis. Results demonstrated the various types of HRM missions and practices in startups and reflect different perspectives of entrepreneurs and employees of human resources management in these companies. Finally, the results illustrated that HRM can play an important role in the growth of these companies. Although research in the field of startups has increased in recent years, the role of HRM in the growth of these companies has rarely been addressed. The present research helps to expand literature related to the role of HRM in the growth of startups by considering the different perspectives of startups' entrepreneurs and employees

    Histological and allometric growth analysis of eye in Caspian kutum, Rutilus kutum Kamensky, 1901 (Teleostei: Cyprinidae) during early developmental stages

    Fish larvae have several sensory systems that are functional at or soon after hatching and then are developed further during larval and juvenile stages. This study was conducted to investigate development of the eye in Rutilus kutum, based on histological and allometric growth analysis during early developmental stages up to 35 day post hatching with emphasis on retinal morphology. For this purpose, the histological sections were prepared and allometric growth pattern of the eye was calculated. The results showed that the most eye's structures along with the retina of the newly hatched larvae, as the inner sensory (photosensitive) tissue were completely differentiated. Allometric growth pattern of the eye diameter up to the inflexion point (7 dph) was somewhat positive and then it became negative. The results revealed that the Caspian kutum is dependence on visual capability as visual feeder during their larval period which itself explains completion of eye structures and the high growth rate of eye before 3 dph i.e. beginning of mixed feeding

    Background: Using local anesthetic is common to control the pain through blocking the nerve reversibly in dental procedures. Gow-Gates (GG) technique has a high success rate but less common. This study aimed to compare the onset time and success rate in GG and standard technique of inferior alveolar nerve block (IANB). Material and Methods: This descriptive, single blind study was consisted of 136 patients (59 males and 77 females) who were randomly received GG or IANB for extraction of mandibular molar teeth. Comparisons between the successes of two anesthetic injection techniques were analyzed with Chi-square test. Incidence of pulpal anesthesia and soft tissue anesthesia were analyzed with Kaplan-Meier method. Mean onset times of pulpal anesthesia, soft tissue and lip numbness were analyzed with Log-Rank test. Comparisons were considered significant at P ≤0.05 by using SPSS software ver.15. Results: The incidence of pulpal anesthesia in the IANB group (canine 49.3%, premolar 60.3%) were not significantly different from the GG group (canine 41.3%, premolar 74.6%) ( P =0.200 and P =0.723). The success rate in the IANB group (80.82%) was not significantly different from the GG group (92.02%) ( P =0.123). Furthermore, onset time of lip and buccal soft tissue numbness in GG group (3.25, 4.96 minutes) was quite similar to IANB group (3.22, 4.89 minutes) (all P values >0.05). Conclusions: Although this study demonstrated higher clinical success rate for GG than IANB technique, no significant differences in success rates and onset time were observed between two techniques
