The Relationship

Purpose Audiologists should be treating hyperacusis patients. However, it can be difficult to know where to begin because treatment protocols and evidence-based treatment studies are lacking. A good place to start in any tinnitus and hyperacusis clinic is to incorporate a group educational session. Method Here, we outline our approach to establishing a hyperacusis group educational session that includes specific aspects of getting to know each patient to best meet their needs, understanding the problems associated with hyperacusis, explaining the auditory system and the relationship of hyperacusis to hearing loss and tinnitus, describing the influence of hyperacusis on daily life, and introducing treatment options. Subjective responses from 11 adults with hyperacusis, who participated in a recent clinical group education session, were discussed to illustrate examples from actual patients. Conclusions Due to the devastating nature of hyperacusis, patients need to be reassured that they are not alone and that they can rely on audiologists to provide support and guidance. A group approach can facilitate the therapeutic process by connecting patients with others who are also affected by hyperacusis, and by educating patients and significant others on hyperacusis and its treatment options.

A group approach having an excess because its scope broader, and in accordance with communal culture of the people. Group dynamics and independency farmers become a yardstick to judge whether the programs the government (the course of development) involving group cattle farmers cut is sustainable or not, so that it can be evaluated for sustainability the next. The purpose of research are (1) analyze group dynamics formed in the group spr mega jaya, (2) analyzed levels of independency of farmers in the farmers spr mega jaya, (3) analyze relations group dynamics and independency of farmers with the success kejar farmers spr mega jaya. Data analysis of analysis descriptive statistics (a frequency, the percentage, on the average), and statistic analysis inferential by test a correlation coefficient rank the spearman. The research results show that group dynamics spr mega jaya tends in category high, and independency of farmers spr mega jaya tends in category enough, while test relations shows that there is a positive connection welfare between group dynamics the cattle farmer and independency of farmers with the success kejar cattle farmers cut. This means that the more dynamic group spr mega jaya and independency of felt farmers high, so the success of the program group farmers who reached the higher.Keywords: group dynamics, independency of groups, sekolah peternakan rakyatABSTRAKPendekatan kelompok memiliki kelebihan karena cakupannya yang lebih luas, dan sesuai dengan budaya masyarakat komunal. Dinamika kelompok dan keberdayaan peternak menjadi tolok ukur untuk menilai apakah program pemerintah (program pembangunan) yang melibatkan kelompok peternak sapi potong bersifat sustainable atau tidak, sehingga dapat dievaluasi untuk keberlanjutan program selanjutnya. Tujuan dari penelitian adalah (1) menganalisis dinamika kelompok yang terbentuk dalam kelompok SPR Mega Jaya, (2) menganalisis tingkat keberdayaan peternak pada kelompok peternak SPR Mega Jaya, (3) menganalisis hubungan dinamika kelompok dan keberdayaan peternak dengan keberhasilan program kelompok peternak SPR Mega Jaya. Analisis data berupa analisis statistik deskriptif (frekuensi, persentase, rata-rata), dan analisis statistik inferensial dengan uji koefisien korelasi rank Spearman. Hasil penelitian menunjukkan bahwa dinamika kelompok SPR Mega Jaya cenderung pada kategori tinggi, dan keberdayaan peternak SPR Mega Jaya cenderung pada kategori cukup, sedangkan uji hubungan menunjukkan bahwa terdapat hubungan positif signifikan antara dinamika kelompok peternak dan keberdayaan peternak dengan keberhasilan program kelompok peternak sapi potong. Hal ini berarti bahwa semakin dinamis kelompok SPR Mega Jaya dan keberdayaan yang dirasakan peternak tinggi, maka keberhasilan program kelompok peternak yang tercapai semakin tinggi.Kata kunci: dinamika kelompok, keberdayaan kelompok, sekolah peternakan rakyat

Neuroimaging Genetics

The Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) consortium brings together researchers from around the world to try to identify the genetic underpinnings of brain structure and function, along with robust, generalizable effects of neurological and psychiatric disorders. The recently-formed ENIGMA Brain Injury working group includes 8 subgroups, based largely on injury mechanism and patient population. This introduction to the special issue summarizes the history, organization, and objectives of ENIGMA Brain Injury, and includes a discussion of strategies, challenges, opportunities and goals common across 6 of the subgroups under the umbrella of ENIGMA Brain Injury. The following articles in this special issue, including 6 articles from different subgroups, will detail the challenges and opportunities specific to each subgroup.
