  هدف پژوهش حاضر، بررسی رابطه کنترل عواطف و تحمل پریشانی با استفاده آسیب زا از تلفن ‌همراه در میان دانشجویان پیام نور تهران بود. پژوهش حاضر از نوع توصیفی- همبستگی است. جامعه آماری این پژوهش کلیه دانشجویان تحصیلات تکمیلی دانشگاه پیام نور واحد شهر تهران در سال تحصیلی 94-1393 می‌باشند. نمونه این تحقیق شامل 160 نفر بود که با روش نمونه‌گیری در دسترس از بین جامعه دانشجویان دانشگاه پیام نور واحد شرق تهران انتخاب شدند. داده‌ها، به وسیله آزمون استفاده آسیب زا از تلفن همراه ویلیامز و همکاران، آزمون کنترل عواطف و مقیاس تحمل پریشانی سیمونز و گاهر گردآوری شد. به منظور آزمون فرضیه ها، با استفاده از نرم‌افزار SPSSاز آزمون های آماری همبستگی پیرسون و تحلیل رگرسیون چندگانه استفاده شده است. نتایج همبستگی پیرسون نشان داد که کنترل عواطف و مؤلفه های آن و هم‌چنین، تحمل پریشانی، با استفاده مفرط دانشجویان از تلفن همراه رابطه منفی و معناداری دارد. هم‌چنین، نتایج رگرسیون چندگانه نشان داد که کنترل عواطف و تحمل پریشانی استفاده مفرط از تلفن همراه را در بین دانشجویان پیش بینی می کند. با توجه به یافته های پژوهشی می توان نتیجه گرفت که کنترل عواطف و تحمل پریشانی نقش مهمی در پیش بینی استفاده آسیب زای دانشجویان از تلفن همراه دارند. لذا، توجه ویژه مسؤولان آموزشی به استرسورهای دانشجویی و تقویت جنبه های مثبت شخصیتی آنان توصیه می‌گردد. تفاصيل المقالة

  The study investigated the roles of different stakeholders influencing the use of mobile phones in accessing agricultural information in Tanzania. While information is becoming an important ingredient in agriculture, farmers in Tanzania suffer the problem of lacking access to agricultural information. Promisingly, mobile phone technology has become the most valued infrastructure which gives people access to information and services they need. Actually, the subscription of mobile phones in Tanzania is ubiquitous and is ever-growing. However, many farmers are not fully utilizing the potential that the technology prevails. There is an apparent disparity between mobile phone subscriptions which is increasingly being adopted on one hand and their uptake into farming practices. The question is, why farmers not fully utilizing the potential the technology prevails in agriculture and how could they be helped?

  The objective of this study was to assess the influence of some socioeconomic characteristics on purposes for which mobile phone was used by small scale farmers in the Gezira State, Sudan. The total number of small- scale farmers in the State for 2013-2014 growing season was estimated to be 5000. Ten percent of the population was used using the simple random sampling technique. The collected data were statistically analyzed and interpreted using percentage, frequency distribution and chi-square test. The results showed significant association between the age, education level and farm size of small scale farmers and their purposes for which mobile phone was used. It can be concluded that the relatively high cost of buying and use of mobile phones can negatively influence the frequency of contacts of small scale farmers particularly their use of mobile phones for agriculture services needed. In addition, the results of this study can help in improving the mobile telephone services which in turn may increase the success of agricultural development programmes in the State and the rest of the country. Thus, more efforts should be paid by mobile telephone service companies of Sudan to expand their services to provide services for all aspects of agricultural activities in the State and use more advanced technology in operating mobile telephone networks in order to reduce cost of buying and using mobile phones particularly for small scale farmers in the Gezira State and the rest of the country. تفاصيل المقالة
