BACKGROUND: Researchers have a moral responsibility to offer to return research results to participants, but the needs and attitudes of parents and adolescents with cancer in paediatric oncology regarding the issue are relatively unknown.OBJECTIVES: To explore the needs of potential research participants or their guardians with respect to the offer of a return of research results. METHODS: A questionnaire was used in a focus group and in telephone interviews with eight adolescents and 12 parents of children with cancer. The participants (...) were asked to respond to the questions and to comment on the inclusiveness of the questionnaire.RESULTS: The majority of participants (18 of 20) wished to receive research results. Two somewhat unexpected findings are described. First, all participants in the present study felt that it was the primary responsibility of the participant to retain contact with the researchers for the purpose of obtaining research results. Second, few participants (n=2) indicated that the Internet would be a satisfactory way of transmitting these results. One-half of the participants wished to have face-to-face communication of results.CONCLUSIONS: These results provide preliminary guidance for the return of research results to participants and validate the use of the questionnaire in a larger study of this issue.

BACKGROUND: The offer of return of research results to study participants has many potential benefits. The current study examined the offer of return of research results by analyzing consent forms from 2 acute lymphoblastic leukemia studies of the 235 institutional members of the Children's Oncology Group. METHODS: Institutional review board (IRB)-approved consent forms from 2 standard-risk acute lymphoblastic leukemia studies (Children's Cancer Group [CCG] 1991 and Pediatric Oncology Group [POG] 9407) were analyzed independently by 2 reviewers. RESULTS: The authors received (...) replies from 202 of the 235 institutions that were contacted (85%). One hundred eighty-one institutions had CCG 1991 (n = 96) or POG 9905 (n = 85) protocols that were approved by an IRB. Most institutions provided contact information for the principal investigator (n = 175; 97%) and a member of the institution's research services office (n = 154; 85%). Only 5 (2.8%) institutions provided an indication of a participant's right to receive a summary of research results; most of these institutions provided details on how (n = 5) or when (n = 5) this was to occur. All of these institutions (n = 162; 89.5%) provided a specific statement offering new information that might affect a participant's decision to continue to participate in a study. Only 2 institutional consent forms offered participants the option to receive research results, and only 10 (5.5%) consent forms contained an unambiguous, specific statement offering to provide new information after the study was closed. CONCLUSIONS: Few institutional review board-approved consent forms explicitly indicate the right of research recipients to receive a summary of the results of the research in which they have participated.

Norms provide a valuable mechanism for establishing coherent cooperative behaviour in decentralised systems in which there is no central authority. One of the most influential formulations of norm emergence was proposed by Axelrod :1095–1111, 1986). This paper provides an empirical analysis of aspects of Axelrod’s approach, by exploring some of the key assumptions made in previous evaluations of the model. We explore the dynamics of norm emergence and the occurrence of norm collapse when applying the model over extended durations. It (...) is this phenomenon of norm collapse that can motivate the emergence of a central authority to enforce laws and so preserve the norms, rather than relying on individuals to punish defection. Our findings identify characteristics that significantly influence norm establishment using Axelrod’s formulation, but are likely to be of importance for norm establishment more generally. Moreover, Axelrod’s model suffers from significant limitations in assuming that private strategies of individuals are available to others, and that agents are omniscient in being aware of all norm violations and punishments. Because this is an unreasonable expectation, the approach does not lend itself to modelling real-world systems such as online networks or electronic markets. In response, the paper proposes alternatives to Axelrod’s model, by replacing the evolutionary approach, enabling agents to learn, and by restricting the metapunishment of agents to cases where the original defection is observed, in order to be able to apply the model to real-world domains. This work can also help explain the formation of a “social contract” to legitimate enforcement by a central authority. (shrink)

After receiving the divine authorization from Allah to openly notify people of Islam, the Messenger of Allah started to publicly to invite the people of Mecca to Islam. Idolaters however felt heavy shame to give up the faith of their ancestors, and the pagans did not accept the Prophet's invitation to Islam. They applied various pressures to the Messenger of Allah and the believers to renounce the cause of Islam. When the animosity against the new Muslims became intolerable, Almighty Allah (...) gave permission to immigrate, first to Habasha and then to Medina. Some of the companions of the Prophet periodically immigrated to Habasha and then to Medina. In the sources that have survived to the present day, poets (ṣaḥāba: companion of the Prophet Muhammad peace be upon him) reflect the events experienced during the immigration to Medina and the intensity of emotions they felt during the holy journey. These poets demonstrate in their writings a sense of elation and pride, having followed the Prophet's favorable advice to immigrate to Medina and portend that their religion will be strengthened in Medina by their presence. Their poems in terms of style are more focused on unscripted, or spontaneous feelings, a style of pauses to give harmony between the shorter verses, unlike long poetic tradition in the period of ignorance (Jāhiliyya).Summary: The Messenger of Allah comes into the world of Mecca, where injustice and distorted belief forms prevail, and when he is forty years old, he is commissioned as a prophet by Allah Almighty. Considering the possibility that the Islamic invitation will not be accepted and welcomed by the pagan Arabs in Mecca, the Prophet tries to spread his cause among the people only he has trusted for three years. When revelation regarding publicly conveying Islam came, the Prophet begins to openly invite the people of Mecca to Islam. Since leaving the beliefs that are patrimonies preponderated the pagans, they started oppressing the Prophet and the believers. When the pressure exerted by the pagans exceeded the limit of tolerance, the Prophet advised the Ṣaḥāba for the temporary migration to Abyssinia. Some Muslims in need of protection followed the advice of the Messenger of Allah, and they migrated to Abyssinia. In the meantime, the Prophet was under the protection of his uncle Abū Ṭālib. After the death of Abū Ṭālib, the pressure on the Prophet increased day by day. Moreover, it was even planned by the pagans to have them eradicated through conspiring against them. The Prophet, who understood that he cannot convey Islam in Mecca, went to Tāif to describe his case. The Prophet, however, faced a harsh reaction in Tāif and was forced to return to Mecca.In the meantime, the people of Medina were in search of a leader to eliminate the mess in consequence of wars and instability with Jews on the one hand and among each other on the other hand. The Prophet came to Mecca in the Ḥājj (pilgrimage) season and also presented the religion of Islam to groups from Medina People who perceived that the Prophet has the features to overcome the disasters between them, they pledge allegiance to the Prophet through the agreements known as Bay‘a al-‘Aqaba in the region called al-‘Aqaba, respectively as Bay‘a al-‘Aqaba I and II. In this way, the city of Medina became ready to welcome the immigrants and to be a base of the Islamic religion that will open up to the world. Almighty Allah is first allowed to Ṣaḥāba and then to Prophet to migrate to Medina and with migration of Prophet to Medina, a significant breakthrough was achieved in the history of Islam.Since the issue of the migration to Medina corresponds to the early period of Islam, the sources of poetry reflected the migration of the Ṣaḥāba to Medina are few in number. Relevant texts in the available sources can be found consist of five articles as, three of them belong to Abū Aḥmad b. Jaḥsh, the fourth belongs to Bujaid b. 'Imran al-Huzâ'î'e and the last one belongs to an unknown poet. Because of his connection to the hegira, a verse pursuant to idolater poet Utbe b. Rabî‘a was also included in the subject. In related poem texts, it is seen that the Ṣaḥābahs poets had prided themselves on the fact that they followed the advice made by the Messenger of Allah on his way to hegira to Medina and they tried to reflect the intensity of emotions they experienced in the face of the developments that occurred since the first moments of the movement of emigration to the poems. Determined to migrate to Medina in order to strengthen the Islamic invitation, the poet Abū Aḥmad reflected the self-confidence of walking on the right way. Abū Aḥmad promised the Messenger of Allah that he will migrate to Medina and he was faithful to his word. Abū Aḥmad tried to resolve his concerns of his wife Umm Aḥmad that they might be harmed by the polytheists if they migrate to Medina and emphasized that they migrate to Medina in order to strengthen the God Almighty against superstitions.Undoubtedly, the concerns of Umm Aḥmad in this context give clues about the dimensions of mobbing, oppression and torture policies applied to Muslims in Mecca. Abū Aḥmad and his associates were full of belief that Almighty Allah will meet their expectations as they migrate to Medina in line with the recommendations of the Prophet. In this respect, the poet turns a deaf ear to the advice of many men, women and friends to not to leave Mecca environment that he was born and grew up in and the memories that adorns his inner life shaped. The poet also points to the importance of the fellowship of Islam, rather than the spirit of Jāhiliyya As a matter of fact, because of tribal chauvinism, the poet called for the termination of hostilities in the past and convinced those around him to follow the call. In this respect, the poet is in peace with the fact that the family members will also have the blessings waiting for those who migrate for Allah. According to the poet, the idolaters who favored blasphemy and who opposed Muslims, deserved the wrath of Allah. Even if there are blood ties with the Muslims, the idolaters who favor the blasphemy and opposed the Muslims are frustrated. In another poem, the poet also boasts Ghanm family, of whom he was a member, because they had fulfilled the promise they had given to the Prophet, that they would migrate to Medina. According to the poet, the Ghanm family is essentially loyal to the Prophet. As a matter of fact, the Ghanm family, which once occupied Mecca and lived off in Mecca, left the lands they lived in for Allah and migrated to Medina in groups of single and two in order to strengthen the invitation to Islam.Poet Bujaid b. ʿImrān al-Khuāz‘i boasts about the fact that Khuzā'a tribe, of which he was a member, that is the lower tribe of the Kaʿb sons, supported the Prophet and some of his people migrated to Medina in his verses. In fact, according to the poet, the members of the Khuzā'a tribe trotted off to the Medina on the advice of the Prophet without wasting any time. Moreover, due to the agreement between the Khuzā'a tribe, who played a key role in the reasons causing conquest of Mecca, and the Prophet, Mecca was conquered and Mecca skies were cleaned from idolatry mist. The Khuzā'a tribe was instrumental owing to their admirable attitude in the conquest of Mecca and the Prophet to gain strength, despite the idolaters who once forced the Prophet to leave Mecca. In the verses of the unidentified poet, it is seen that the names of the eight Ṣaḥāba who were subjected to oppression in the most troubled early periods of Islam, who left their homeland for Allah, migrated to Abyssinia or Medina and were heralded to enter heaven were mentioned. According to an unidentified poet, it is not possible for anyone to reach the rankings of these eight people due to the beautiful actions they performed.In the last poem text, it is seen that the poet Abū Aḥmad was dissatisfied with the confiscation and sale of his house by Abū Sufyān when he emigrated to Medina. In the verses, the poet likens his home being unjustly confiscated by Abū Sufyān to a hunter holding the dove he seized tightly and he emphasizes that he will get his due in the afterlife from Abū Sufyān.The poetry texts bearing the traces of migration to Medina are a continuation of the poetry technique of the period of Jāhiliyya in terms of the poetry technique, when wordings that are in accordance with the spirit of Islam are left aside. As a matter of fact, poets try to reflect the intensity of emotions they live in short verses instead of long term poems. Again, poets use the types of art, such as borrowing, metaphor and comparison, which are frequently used in the poetry of the Jāhiliyya in order to bring the intensity of emotion they live in closer to the audience's perception. Poets build on these poems on taweel, muteqâreb, baseet and qamel, which are frequently found poetic measures in the poetry of Jāhiliyya. As a last word, it is necessary to say that the poetry texts of Ṣaḥāba poets are historical objects in terms of shedding light on the events experienced during the Hijra. Again, the poem texts in question are important in terms of getting an idea about the state of old Arabic poetry during the transition period from the period of Jāhiliyya to the period of Islam.
