Revolutionary Mothers: Women in the North Korean Revolution, 1945–1950
Authors: Kim Suzy 
Published: October 2010

Women today are struggling with all their passion and all their strength day and night for the creation of a new history of a democratic country. Today in the streets, men, women, the old, the young, everyone stops to listen to the women.———Nam Hyǒn-sǒ, “Women of a New Country,” January 1947In Korea from ancient times, the master of the home was thought to refer to the husband … we now realize that the master of the home must be the woman, that is, the wife or mother.———Chang Chǒng-suk, “The New Home and Housewife,” October 1947All social revolutions in modern history, from the Russian Revolution of 1917 to the Cuban one of 1959, have attempted to address the status of women as a critical element of social change.1North Korea was no different. With Japan's defeat in World War II, Korea was liberated from its thirty-five-year colonial rule, and as in many postcolonial nations after the war, revolution was in the air.2When the Cold War came early to the peninsula, Korea took two divergent paths. Divided at the 38th parallel into separate occupation zones, with the United States in the south and the USSR in the north, social reforms were carried out swiftly in the north, aided and abetted by the Soviets, while in the south, the American occupiers saw most Korean political movements as too radical and suppressed them. In what follows, I focus on the formative years of early North Korean history, the five-year period between the end of Japanese colonial rule in 1945 and the start of the Korean War in 1950. I show how North Korea from the outset attempted to meld the old and the new through the figure of the revolutionary mother as a uniquely feminine revolutionary subjectivity. This sets the North Korean case apart from other historical examples of social revolutions and their handling of “the woman question.”
Non-voice-related throat symptoms: comparative analysis of laryngopharyngeal reflux and globus pharyngeus scales

Published: October 2010

AbstractBackground:This study calculated the comparability of two throat symptom assessment scales devised to evaluate either laryngopharyngeal reflux or globus.Setting:United Kingdom hospital out-patient departments.Method:A total of 334 subjects, with and without throat symptoms, completed the Reflux Symptom Index and/or the Glasgow and Edinburgh Throat Scale. The following were calculated for the resultant data: Cronbach's α coefficient, principal component analysis, Kaiser normalisation, varimax and oblimin rotation, and eigenvalues.Results:Analysis of data from the Reflux Symptom Index and the Glasgow and Edinburgh Throat Scale revealed clearly similar symptom domains regarding (1) coughing and blockage, and (2) globus or postnasal drip or throat-clearing, as did combined analysis of their amalgamated items. Both instruments had good overall internal consistency (α = 0.75 and 0.81, respectively). The ‘heartburn or reflux’ item in the Reflux Symptom Index mapped poorly to each underlying factor.Discussion:The most commonly used laryngopharyngeal reflux and globus assessment questionnaires appear to detect very similar symptom clusters. The management of throat disorders may previously have been over-reliant on the presenting pattern of throat symptoms. Our findings indicate a need to revisit the traditional clinical classification of throat symptoms.
A first modern contribution to Caloplaca biodiversity in South Korea: two new species and some new country records

Published: October 2010

AbstractEleven species are recognized of which C. bogilana and C. subflavorubescens are described here as new to science while nine species (C. cinnabarina, C. decipiens, C. ferruginea, C. inconspecta, C. pellodella, C. scopularis, C. stantonii, C. squamosa and C. subsoluta) are reported for the first time for South Korea. Both new species are peculiar due to their secondary chemistry; anthraquinones along with atranorin, gyrophoric acid and lecanoric acid in C. bogilana, and gyrophoric acid together with anthraquinones in C. subflavorubescens.
Determination of usnic and perlatolic acids and identification of olivetoric acids in Northern reindeer lichen (Cladonia stellaris) extracts
Authors: SMEDS Annika I. , KYTÖVIITA Minna-Maarit 
Published: October 2010

AbstractThe ecologically important lichen Cladonia stellaris forms thick carpets in boreal forest floors. In addition to affecting temperature and water conditions in the soil underneath, the secondary metabolites formed by the lichen layer are of ecological interest. In this paper, we investigated the distribution of lichen acids in C. stellaris collected at different latitudes in Finland and developed methods to quantify the two optical enantiomers of usnic acid separately. The lichen extracts were analysed by high-performance liquid chromatography (HPLC) with UV and mass spectrometric (MS) detection and by gas chromatography with flame ionization (GC-FID) and MS detection. Usnic acid and perlatolic acid were quantified using GC-FID. The concentration of usnic acid in the top 20 mm of the lichen thallus ranged from 0·48–3·08% of dry weight, and that of perlatolic acid from 0·08–0·54%. The enantiomeric composition of usnic acid was determined using a chiral HPLC column coupled to an electrospray ionization-tandem mass spectrometer. (−)-Usnic acid was found to be the predominating enantiomer in all extracts; the proportion of (+)-usnic acid ranged from 0·4%–10·0%. Olivetoric acid methyl ester, diphenylmethanol, and 5-pentylresorcinol were identified, and several other olivetoric acid-type compounds were tentatively identified in the extracts.

Stable standing waves for the two-dimensional Klein–Gordon–Schrödinger system
Authors: Kikuchi Hiroaki 
Published: October 2010

AbstractWe study the orbital stability of standing waves for the Klein–Gordon–Schrödinger system in two spatial dimensions. It is proved that the standing wave is stable if the frequency is sufficiently small. To prove this, we obtain the uniqueness of ground state and investigate the spectrum of the appropriate linearized operator by using the perturbation method developed by Genoud and Stuart and Lin and Wei. Then we apply to our system the general theory of Grillakis, Shatah and Strauss.
One good thing leads to another: Cascades of positive youth development among American adolescents
Authors: Lewin-Bizan Selva , Bowers Edmond P. , Lerner Richard M. 
Published: October 2010

AbstractDevelopmental cascades are links across the life span among heterotypic (qualitatively distinct) variables associated with one or more levels of organization within the ecology of human development. Using data from the longitudinal, 4-H Study of Positive Youth Development (PYD), we illustrate a developmental systems theory predicated model of cascades in the relations between individuals and contexts that promote positive development among adolescents. Consistent with expectations about the bases of PYD and the role in such development on person and context, ecological resources associated with parenting are linked to individual self-regulatory behaviors that in turn impact PYD, which is then associated with youth community contributions. We discuss the limitations and future directions of this research and the implications of developmental cascades for applications to policies and programs.
Intergenerational transmission of depression: A launch and grow model of change across adolescence
Authors: Garber Judy , Cole David A. 
Published: October 2010

AbstractThe present study tested a “launch-and-grow” type of cascade model in which an earlier risk factor (e.g., exposure to maternal depression by age 12) was hypothesized to predict several risk processes during development (e.g., stress, family relationships, self-worth [SW]), which then set the course for the growth of children's depressive symptoms over time. Participants were 240 mothers and children (mean age = 11.87 years, SD = 0.57) who were evaluated annually across 6 years. The Structured Clinical Interview for DSM diagnoses was used to assess mothers' psychiatric history; 185 mothers had had a mood disorder and 55 mothers were lifetime free of psychiatric diagnoses. At each assessment, mothers completed measures of their current level of depressive symptoms and stressful life events; adolescents completed measures about their perceptions of the family environment and their SW; and clinicians rated adolescents' level of depressive symptoms based on separate interviews with the adolescent and mother. Latent growth curve analyses revealed that history of maternal depression significantly predicted the intercepts of the growth trajectories of adolescents' depressive symptoms, mothers' current depressive symptoms, stressful life events, family environment, and adolescents' SW. The intercepts of each of these variables then predicted the trajectory (i.e., slope) of the growth of adolescents' depressive symptoms across the 6 years of the study. These results were consistent with the hypothesized model of maternal depression launching a set of risk factors, which in turn predict the growth of depressive symptoms during adolescence. Implications for interventions aimed at preventing depression in at-risk youth are discussed.
Changes in genetic and environmental influences on the development of nicotine dependence and major depressive disorder from middle adolescence to early adulthood

AbstractThis longitudinal study used a representative community sample of same-sex twins (485 monozygotic pairs, 271 dizygotic pairs) to study longitudinal changes in genetic and environmental influences on nicotine dependence (NicD) symptoms and major depressive disorder (MDD) symptoms and the longitudinal relationships between NicD and MDD symptoms at three relatively discrete ages spanning middle adolescence to early adulthood (ages 15, 18, and 21). Clinical interviews were used to assess NicD and MDD symptoms lifetime at age 15 and during the previous 3 years at the two subsequent assessments. Biometric models revealed similar patterns of findings for NicD and MDD. Heritability increased with age, particularly between ages 15 and 18. Shared environmental influences were small, and the proportion of variance attributed to shared environmental influences decreased with age. Nonshared environmental influences were moderate to large in magnitude and were entirely age specific. Both NicD and MDD symptoms showed considerable stability from age 15 to 21, and at each age those with one disorder showed elevated rates of the other. However, a cross-lagged model revealed no longitudinal predictive relationships between MDD symptoms and NicD symptoms after accounting for stability of symptoms within disorders. In summary, the transition between middle and late adolescence is a critical period for developmental shifts in the magnitudes of genetic and environmental influences on both MDD and NicD symptoms. Despite similarities in the development of genetic and environmental influences for the two phenotypes, the association between NicD and MDD reflects concurrent covariation rather than one phenotype being an antecedent influence on the subsequent development of the other.
Continuity and cascade in offspring of bipolar parents: A longitudinal study of externalizing, internalizing, and thought problems

AbstractThere is growing evidence that many offspring of bipolar parents will develop moderate to severe forms of psychopathology during childhood and adolescence. The purpose of this study was to apply growth curve models to evaluate developmental progression with regard to continuity and cascades representative within the context of a family risk study of bipolar disorder (BD). Repeated assessments of externalizing, internalizing, and thought problems, spanning more than a decade, were examined in a total of 94 offspring of parents with BD (O-BD), major depressive disorder (O-UNI), or no significant psychiatric or medical problems (O-WELL). Continuity was defined by the growth curve of the O-WELL group who exhibited low levels of problems from early childhood through late adolescence. Discontinuity, as evidenced by greater complexity of growth curves relative to the O-WELL group, was exhibited in the at- risk offspring groups for internalizing problems. Different patterns of developmental cascades were supported for the at-risk group with O-UNI showing a robust cascade from self-regulatory deficits (externalizing problems) to internalizing problems. There was also support for a cascade from self-regulatory deficits to thought problems across the entire group (with some support that this pattern was accounted for primarily by O-BD). This study not only serves to advance our understanding of the risks associated with a family history of BD, but also provides a novel approach to examining developmental cascades.
A source, a cascade, a schizoid: A heuristic proposal from The Longitudinal Study of Personality Disorders
Authors: Lenzenweger Mark F. 
Published: October 2010

AbstractIt is argued that personality pathology represents the final emergent product of a complex interaction of underlying neurobehavioral systems as well as environment inputs. A number of factors may be involved in the developmental pathway and a cascading of effects is plausible, although a unifying cascade for all personality disorders is not likely. The present study suggests a possible cascade relevant to one personality disorder: schizoid personality disorder in emerging adulthood. In brief, it is hypothesized that the absence of a relationship characterized by a rich degree of psychological proximal process in early childhood, which is associated with nurturance and the facilitation of more complex development, predicts impairment in the actualization of the affiliation system (i.e., that system that facilitates interpersonal connectedness and social bonds in human beings and is under substantial genetic influence), and this impairment in the affiliation system predicts the appearance of schizoid personality disorder symptoms in emerging adulthood (late teens/early 20s), which persists over time into emerging adulthood. The impairment in the affiliation system is argued to proceed through childhood sociality as reflected in temperament on through adult personality as reflected in communal positive emotion. Furthermore, it is also hypothesized that the relationship between proximal processes and the affiliation system maintains irrespective of other childhood temperament factors that might adversely impact early parent/caregiver and child relations. The data for a preliminary illustration of this possible cascade are drawn from The Longitudinal Study of Personality Disorders, which is a prospective, multiwave study of personality disorders, personality, and temperament in a large sample of adults drawn from a nonclinical population.
On the origin and evolution of life in the Galaxy
Authors: McCabe Michael , Lucas Holly 
Published: October 2010

AbstractA simple stochastic model for evolution, based upon the need to pass a sequence ofncritical steps is applied to both terrestrial and extraterrestrial origins of life. In the former case, the time at which humans have emerged during the habitable period of Earth suggests a value ofn=4. Progressively adding earlier evolutionary transitions gives an optimum fit whenn=5, implying either that their initial transitions are not critical or that habitability began around 6 Ga ago. The origin of life on Mars or elsewhere within the Solar System is excluded by the latter case and the simple anthropic argument is that extraterrestrial life is scarce in the Universe because it does not have time to evolve. Alternatively, the timescale can be extended if the migration of basic progenotic material to Earth is possible. If extra transitions are included in the model to allow for Earth migration, then the start of habitability needs to be even earlier than 6 Ga ago. Our present understanding of Galactic habitability and dynamics does not exclude this possibility. We conclude that Galactic punctuated equilibrium, proposed as a way round the anthropic problem, is not the only way of making life more common in the Galaxy.
Hearing Loss Is Negatively Related to Episodic and Semantic Long-Term Memory but Not to Short-Term Memory

Published: October 2010

PurposeTo test the relationship between degree of hearing loss and different memory systems in hearing aid users.MethodStructural equation modeling (SEM) was used to study the relationship between auditory and visual acuity and different cognitive and memory functions in an age-hetereogenous subsample of 160 hearing aid users without dementia, drawn from the Swedish prospective cohort aging study known as Betula (L.-G. Nilsson et al., 1997).ResultsHearing loss was selectively and negatively related to episodic and semantic long-term memory (LTM) but not short-term memory (STM) performance. This held true for both ears, even when age was accounted for. Visual acuity alone, or in combination with auditory acuity, did not contribute to any acceptable SEM solution.ConclusionsThe overall relationships between hearing loss and memory systems were predicted by the ease of language understanding model (J. Rönnberg, 2003), but the exact mechanisms of episodic memory decline in hearing aid users (i.e., mismatch/disuse, attentional resources, or information degradation) remain open for further experiments. The hearing aid industry should strive to design signal processing algorithms that are cognition friendly.
The Effect of Listener Experience and Anchors on Judgments of Dysphonia
Authors: Eadie Tanya L. , Kapsner-Smith Mara 
Published: October 2010

Purpose
To determine the effect of auditory anchors on judgments of overall severity (OS) and vocal effort (VE) in dysphonic speech when judgments are made by experienced and inexperienced listeners, and when self-rated by individuals with dysphonia (speaker–listeners).

Method
Twenty individuals with dysphonia and 4 normal controls provided speech recordings. Speaker–listeners judged their own speech samples for OS and VE without auditory anchors, and then in the presence of anchors, using 100-mm visual analog scales (VAS). Twenty inexperienced and 10 experienced listeners evaluated the same speech samples for OS and VE in similar rating conditions. Twenty inexperienced listeners also made judgments of the speech samples solely in anchored conditions.

Results
All listeners judged the speech samples as significantly less severe and effortful in the anchored conditions. No significant effects of anchors or experience were found for intrarater agreement within 7.14 mm on the VAS. Both inexperienced and experienced listeners were significantly less variable and showed improved interrater agreement in the anchored conditions. Anchors significantly improved agreement across groups of listeners, particularly between inexperienced and speaker–listeners.

Conclusion
Listeners systematically shift judgments of voice quality in response to auditory anchors. Anchors reduce interrater variability and may improve agreement across some types of listeners.
Protein–ice interaction of an antifreeze protein observed with solid-state NMR

Published: October 2010

NMR on frozen solutions is an ideal method to study fundamental questions of macromolecular hydration, because the hydration shell of many biomolecules does not freeze together with bulk solvent. In the present study, we present previously undescribed NMR methods to study the interactions of proteins with their hydration shell and the ice lattice in frozen solution. We applied these methods to compare solvent interaction of an ice-binding type III antifreeze protein (AFP III) and ubiquitin a non-ice-binding protein in frozen solution. We measured1H-1H cross-saturation and cross-relaxation to provide evidence for a molecular contact surface between ice and AFP III at moderate freezing temperatures of -35 °C. This phenomenon is potentially unique for AFPs because ubiquitin shows no such cross relaxation or cross saturation with ice. On the other hand, we detected liquid hydration water and strong water–AFP III and water–ubiquitin cross peaks in frozen solution using relaxation filtered2H and HETCOR spectra with additional1H-1H mixing. These results are consistent with the idea that ubiquitin is surrounded by a hydration shell, which separates it from the bulk ice. For AFP III, the water cross peaks indicate that only a portion of its hydration shell (i.e., at the ice-binding surface) is in contact with the ice lattice. The rest of AFP III’s hydration shell behaves similarly to the hydration shell of non-ice-interacting proteins such as ubiquitin and does not freeze together with the bulk water.

The evolution of Earth’s biota is intimately linked to the oxygenation of the oceans and atmosphere. We use the isotopic composition and concentration of molybdenum (Mo) in sedimentary rocks to explore this relationship. Our results indicate two episodes of global ocean oxygenation. The first coincides with the emergence of the Ediacaran fauna, including large, motile bilaterian animals, ca. 550–560 million year ago (Ma), reinforcing previous geochemical indications that Earth surface oxygenation facilitated this radiation. The second, perhaps larger, oxygenation took place around 400 Ma, well after the initial rise of animals and, therefore, suggesting that early metazoans evolved in a relatively low oxygen environment. This later oxygenation correlates with the diversification of vascular plants, which likely contributed to increased oxygenation through the enhanced burial of organic carbon in sediments. It also correlates with a pronounced radiation of large predatory fish, animals with high oxygen demand. We thereby couple the redox history of the atmosphere and oceans to major events in animal evolution.
