- چکیده:
- چکیده انگلیسی: The aim of the research was analysis of rice producers’ perceptions of participatory communication in the use of integrated pest management (IPM). Research population was consisted of rice producers in the west of Mazandaran province (N=16126), whose 187 ones were selected using Cochran’s formula. Data were gathered by systematic random sampling method. The instrument for data collection was a questionnaire which its validity was confirmed by a panel of experts. Its reliability was confirmed by Cronbach's alpha coefficients. Results of descriptive statistics showed that the rice producers are in the good status in terms of use of integrated pest management’s technologies. The results of ANOVA showed that there are significant differences among rice producers based on their perceptions of participatory communication and use of integrated pest management. Rice producers with higher perception use integrated pest management’s technologies more than others. The results of the correlation coefficient also showed that there is significant positive relationship among all factors related to perceptions of participatory communication (individual effect, contextual education, information receiving and Agricultural Jihad’s flexibility) and the use of integrated pest management, except to the information sending one. Stepwise regression analysis showed that two factors including Agricultural Jihad’s flexibility and contextual education can explain 70/02% of the changes in the dependent variable (use of IPM)

- چکیده: هدف از این مطالعه، شناسایی عوامل خارجی مؤثر بر مدیریت استراتژیک در نظام دانش و اطلاعات کشاورزی و بررسی اهمیت نسبی آن از دیدگاه کارشناسان میباشد. براساس مصاحبه ها، بررسی ادبیات مربوطه و تحقیقات قبلی، پنج عامل مؤثر برای بررسی تعیین شد. برای این منظور، یک پرسشنامه طراحی گردید. اعتبار صوری و محتوایی این ابزار سنجش نیز توسط کمیته تحقیقاتی تأیید شد. برای تعیین قابلیت اطمینان این ابزار، یک مطالعه آزمایشی توسط 30 نفر از پرسنل سازمان جهاد کشاورزی استان قزوین انجام شد. ضریب اطمینان (آلفای کرونباخ) 95/0 محاسبه شد که نشان دهنده این است که پرسشنامه دارای شاخص اعتماد بالایی بوده است. عوامل خارجی مورد بررسی در این تحقیق عبارت بودند از عوامل اجتماعی - فرهنگی، سیاسی، اقتصادی، تکنولوژیکی و زیستمحیطی. جامعه آماری نیز شامل کارشناسان ستادی و کارکنان سازمانهای کشاورزی استانهای البرز و تهران (161 نفر) بود. تجزیه و تحلیل داده ها با استفاده از نرم افزار SPSS ورژن 20 انجام شد. نتایج نشان داد که عوامل اجتماعی- فرهنگی، اقتصادی، بومشناختی، سیاسی،تکنولوژیکی به ترتیب از مهمترین عوامل خارجی مؤثر بر مدیریت استراتژیک دانش و اطلاعات کشاورزی میباشند.
- چکیده انگلیسی: The purpose of this study was to identify external factors affecting strategic management in agricultural knowledge and information system and to examine their relative importance from experts’ point of view. Five factors were identified based on the interviews, examination of relevant literature and previous researches; In line with that, a questionnaire was developed to suit this purpose. Face and content validity of the research instrument verified by the research committee. To determine the reliability of the instrument, a pilot study was conducted with 30 Agriculture - Jihad Organization personnel from Qazvin Province. The reliability coefficient (Cronbach’s Alpha) was computed 0.95, which indicated that the questionnaire had a high reliability index. External factors consisted of sociocultural, policy, economic, technological, and ecological factors. The statistical population was consisted of line and staff experts of Agriculture Organizations of Alborz and Tehran Provinces (N=161). Data was analyzed by SPSSwin20 software. The results showed that sociocultural, economic, ecological, policy and technological factors were the most important external factors affecting strategic management in agricultural knowledge and information respectively.

- چکیده: امروزه، میان سازمانها توافقی وجود دارد که تقویت آموزش و پرورش منجر به بهبود عملکرد سازمانی میشود. تأکید بر سرمایههای انسانی در سازمانها نشاندهنده این دیدگاه است که ارزشهای بازار وابستگی کمتری به منابع ملموس دارد و بیشتر به منابع ناملموس، به ویژه منابع انسانی مرتبط است. باتوجه به این، هدف اصلی این مطالعه، طراحی مدلی برای اعضای هیات علمی در آموزش عالی کشاورزی ایران بود. جمعآوری دادهها در نه دانشکده کشاورزی به روش پیمایشی انجام شد. تعداد 284تن اعضای هیات علمی با استفاده از روش نمونهگیری تصادفی ساده جمعآوری شدند. ابزار تحقیق پرسشنامهای بود که روایی و پایایی آن با استفاده از روش مدل معادلات ساختاری و نرمافزار لیزرل محاسبه شد. در نهایت، مدلی برای اعضای هیئت علمی در نظام آموزش عالی کشاورزی ایران ارائه شد. یافته ها نشان دادند که متغیرهای زمینهای (یعنی، توسعه فردی، سازمانی، اجتماعی، آموزشی، و حرفهای) اثرات مستقیم بر فرایند توسعه اعضای هیئت علمی دارد. علاوه بر این، توسعه فردی و سازمانی، اثرات مستقیم و غیر مستقیم در توسعه اعضای هیئت علمی دارند (R2 = 0.70).
- چکیده انگلیسی: Nowadays, there is an agreement among organizations that reinforcing of education leads to the improvement of organizational performance. The emphasis on the human capital in organizations reflects the view that market values depend less on tangible resources, but more on intangible ones, particularly human resources. The main purpose of this study was to design a model for faculty members in public Agricultural Higher Education in Iran. A survey method was used to collect data from nine Public Agricultural Faculties in Iran. Samples were collected from faculty members using a simple random sampling method (n=284) and a questionnaire was used as the main research instrument to collect data. Reliability and validity were calculated using Structural Equation Modeling through LISREL software, version 8.54 (above 0.7). Finally, a model was developed and tested for faculty members in Agricultural Higher Education System in Iran. The findings showed that contextual variables (i.e. personal, organizational, social, educational, and professional development) had direct impacts on the process of Human Resource Development (HRD). Furthermore, personal and organizational development had direct and indirect impacts on HRD (R2 = 0.70).

- چکیده:
- چکیده انگلیسی: Objective: Antiepileptic drugs (AEDs) that are usually used for treatment of epilepsy have substantial side effects and about 30% of patients continue to have seizures with current AEDs therapy. Some herbs which traditionally used in the management of seizures of many rural areas of the developing countries have shown anticonvulsant activity in modern pharmacological bioassays. The aim of the present study was to evaluate the effects of berberine, an alkaloid from Berberis vulgaris, on seizures induced by pentylenetetrazol (PTZ) in rats. Material and Methods: Rats (n=6-7) received berberine (100, 200 and 400 mg/kg, i.p.), diazepam (4mg/kg, i.p. as positive control), and vehicle (saline) and then 30 min later PTZ (110mg/kg, i.p.) were injected . Behavioral responses of the animals to PTZ administration were evaluated using these criteria: latency to first minimal clonic seizure (MCS), incidence of MCS, latency to the first generalized tonic–clonic seizures (GTCS), incidence of GTCS, protection against GTCS and mortality. Results: Intraperitoneal administration of lower doses of berberine (100 and 200 mg/kg) had no significant effects on minimal clonic seizures (MCS) and generalized tonic-clonic seizures (GTCS) latencies, while injection of 400 mg/kg caused significant increase in both MCS and GTCS latencies (p<0.05). In this study diazepam, (4 mg/kg) 30 min prior to PTZ, significantly increased GTCS latency. Berberine at tested doses had no protection against mortality following PTZ administration. Conclusion: It can be concluded that berberine at high doses could be a useful protective agent in PTZ-induced epileptic seizures in rats.
