We describe some characteristics of persistent musical and verbal retrieval episodes, commonly known as "earworms." In Study 1, participants first filled out a survey summarizing their earworm experiences retrospectively. This was followed by a diary study to document each experience as it happened. Study 2 was an extension of the diary study with a larger sample and a focus on triggering events. Consistent with popular belief, these persistent musical memories were common across people and occurred frequently for most respondents, and were often linked to recent exposure to preferred music. Contrary to popular belief, the large majority of such experiences were not unpleasant. Verbal earworms were uncommon. These memory experiences provide an interesting example of extended memory retrieval for music in a naturalistic situation.

Various studies suggest that non-rapid eye movement (NREM) sleep, especially slow-wave sleep (SWS), is vital to the consolidation of declarative memories. However, sleep stage 2 (S2), which is the other NREM sleep stage besides SWS, has gained only little attention. The current study investigated whether S2 during an afternoon nap contributes to the consolidation of declarative memories. Participants learned associations between faces and cities prior to a brief nap. A cued recall test was administered before and following the nap. Spindle, delta and slow oscillation activity was recorded during S2 in the nap following learning and in a control nap. Increases in spindle activity, delta activity, and slow oscillation activity in S2 in the nap following learning compared to the control nap were associated with enhanced retention of face-city associations. Furthermore, spindles tended to occur more frequently during up-states than down-states within slow oscillations during S2 following learning versus S2 of the control nap. These findings suggest that spindles, delta waves, and slow oscillations might promote memory consolidation not only during SWS, as shown earlier, but also during S2.

As a reader, I am drawn to pieces that flirt with the boundaries between prose and poetry and I believe these preferences are evidenced in my own work, which not only encompasses creative nonfiction and poetry, but which also teases its way along the line separating the two. In The Atlantic and Everything After, I have worked with both prose poetry and the lyric essay, two styles that combine and highlight the different strengths of creative nonfiction and poetry.I created this work to explore the transformation I embarked upon when I first boarded that plane to Nova Scotia in August 2009. I created it to pay homage to the people and places that have moved or changed me. I created it to acknowledge the many similarities of travel and writing, both of which are often ugly, uncomfortable, a bit frightening, and terribly frustrating.In the process of its creation, I was forced to confront painful and delightful memories, to realize the significance of those memories within my own heart. I exercised the modes of poetry and nonfiction (and a few in between) in order to bring the many complicated aspects of travel together in a way that does its discomfort and enchantment equal justice. I have filled the pages of The Atlantic and Everything After with my poems and my prose, my own life-cherishing force. I am pleased to welcome you to it.

WE INVESTIGATED HOW WELL STRUCTURAL FEATURES such as note density or the relative number of changes in the melodic contour could predict success in implicit and explicit memory for unfamiliar melodies. We also analyzed which features are more likely to elicit increasingly confident judgments of "old" in a recognition memory task. An automated analysis program computed structural aspects of melodies, both independent of any context, and also with reference to the other melodies in the testset and the parent corpus of pop music. A few features predicted success in both memory tasks, which points to a shared memory component. However, motivic complexity compared to a large corpus of pop music had different effects on explicit and implicit memory. We also found that just a few features are associated with different rates of "old" judgments, whether the items were old or new. Rarer motives relative to the testset predicted hits and rarer motives relative to the corpus predicted false alarms. This data-driven analysis provides further support for both shared and separable mechanisms in implicit and explicit memory retrieval, as well as the role of distinctiveness in true and false judgments of familiarity.

A modified uvulopalatopharyngoplasty (UPPP) was carried out between January 1992 and December 2003 at the ENT Department of the Inselspital in Bern in 146 patients with habitual or complicated rhonchopathy. The operation consisted of a classical tonsillectomy or residual tonsil resection and additional shortening of the uvula. The natural mucosal fold between the uvula and the upper pole of the tonsils was carefully preserved. A wide opening to the rhinopharynx was created by asymmetric suturing of the glossopalantine and pharyngopalatine arches. A retrospective questionnaire with regard to rhonchopathy, phases of apnea, daytime drowsiness, obstruction of nasal breathing, long-term complications and patient satisfaction was used to evaluate the short-term and long-term effectiveness of the modified UPPP as well as the incidence of adverse side effects. Complete postoperative courses were evaluated in 116 patients. Surgical complications were restricted to one case with postoperative hemorrhage. A velum insufficiency or postoperative rhinopharyngeal stenosis did not occur. Eighty-three patients (72%) confirmed a persistent suppression or substantial improvement of the rhonchopathy. Disappearance or decrease of sleep apnea was confirmed in 12 (63%) out of 19 postoperative polysomnographic follow-up investigations. Long-term complications occurred in a total of 27 (23%) of 116 patients. They were confined to minor problems such as dryness of the mouth (n = 12), slight difficulty in swallowing (n = 7), discrete speech disturbances (n = 1), and slight pharyngeal dysesthesias (n = 7) with feeling of a lump in the throat and compulsive clearing of the throat. Eighty-five patients (73%) reported that they were satisfied with the postoperative result even several years after the operation. Looking back, 31 patients (27%) would no longer have the operation performed. The inadequate result of the rhonchopathy was specified as the reason by 21 patients. Ten patients had unpleasant memories of the operation because of intensive postoperative pain. Snoring and apneic phases are suppressed or improved by non-traumatic UPPP in the majority of patients. This effect persisted even years after the operation.

In the culture of primal peoples, the dumbbell-shaped bottle gourd or calabash is a symbol for the universe, two equal halves inextricably linked. They represent heaven and earth, Yin and Yang--balance and harmony. This essay reflects personal memories, where case histories, patient stories and a doctor's story are intertwined.

Spontaneous confabulation is a rare memory disorder resulting from orbitofrontal damage or disconnection. Patients act on the basis of memories that do not pertain to the current situation, and are disoriented. No medical treatment is known. Recent studies suggest that subcortical dopaminergic structures are involved in the selection of currently relevant memories. We present a patient who regained the ability to adapt thought and behavior to ongoing reality when treated with risperidone, a dopamine antagonist.

If the profession of social work is to have a future we must know where it came from, and the series of portraits of our pioneers is one of the paths into the origins of that profession. I feel grateful to the publishers for this online-journal and also honoured to be asked to continue the series on pioneers in social work. I gladly comply because, in connection with my research on Alice Salomon and other social workers who were expelled from Germany and other Nazi-occupied territories (Wieler1989 and 1995) I had the pleasure and privilege of meeting and interviewing Walter Friedländer shortly before he passed away. It is years ago that I visited him in his home among stacks of books and piles of papers. My memories are vivid. I still see his sparkling eyes and hear his soft voice with a very heavy German accent. I was most impressed by his memory of historical events and people which, it seemed, only a large hard-drive could retain these days. Now, I wish I had asked more questions but instead, we will have to rely largely on primary and secondary literature and box upon box of archival materials. I draw heavily on the comprehensive German and Jewish Intellectual Emigré Collection (http://library.albany.edu/speccoll/findaids/ger003.htm) which consists of nearly 50 cubic feet and another collection of the German Central Institute („Deutsches Zentralinstitut für Soziale Fragen-DZI“) in Berlin (www.dzi.de). Some of the more current archival materials were lost in a flood, and much of Friedländer’s early memorabilia up to 1933 was lost in Germany. There are also internet resources with widely differing information. I hope that I will not have overlooked too much in order to do justice to this remarkable pioneer and colleague. In order to appreciate and pay tribute to Walter Friedländer and his contributions we will have to reconsider the historical and international context of more than the 93 years of his life span: the German Monarchy, the Weimar Republic, Nazi-Fascism, Swiss, French and American exile and numerous visits to other countries.

Both climate change and socio-economic development will significantly modify the supply and consumption of water in future. Consequently, regional development has to face aggravation of existing or emergence of new conflicts of interest. In this context, transdisciplinary co-production of knowledge is considered as an important means for coping with these challenges. Accordingly, the MontanAqua project aims at developing strategies for more sustainable water management in the study area Crans-Montana-Sierre (Switzerland) in a transdisciplinary way. It strives for co-producing system, target and transformation knowledge among researchers, policy makers, public administration and civil society organizations. The research process basically consisted of the following steps: First, the current water situation in the study region was investigated. How much water is available? How much water is being used? How are decisions on water distribution and use taken? Second, participatory scenario workshops were conducted in order to identify the stakeholders’ visions of regional development. Third, the water situation in 2050 was simulated by modeling the evolution of water resources and water use and by reflecting on the institutional aspects. These steps laid ground for jointly assessing the consequences of the stakeholders’ visions of development in view of scientific data regarding governance, availability and use of water in the region as well as developing necessary transformation knowledge. During all of these steps researchers have collaborated with stakeholders in the support group RegiEau. The RegiEau group consists of key representatives of owners, managers, users, and pressure groups related to water and landscape: representatives of the communes (mostly the presidents), the canton (administration and parliament), water management associations, agriculture, viticulture, hydropower, tourism, and landscape protection. The aim of the talk is to explore potentials and constraints of scientific modeling of water availability and use within the process of transdisciplinary co-producing strategies for more sustainable water governance.

Decades of research on the cellular mechanisms of memory have led to the widely held view that memories are stored as modifications of synaptic strength. These changes involve presynaptic processes, such as direct modulation of the release machinery, or postsynaptic processes, such as modulation of receptor properties. Parallel studies have revealed that memories might also be stored by nonsynaptic processes, such as modulation of voltage-dependent membrane conductances, which are expressed as changes in neuronal excitability. Although in some cases nonsynaptic changes can function as part of the engram itself, they might also serve as mechanisms through which a neural circuit is set to a permissive state to facilitate synaptic modifications that are necessary for memory storage.
