Strategic Orientation and Nursing Home Response to Public Reporting of Quality Measures: An Application of the Miles and Snow Typology
Authors: Zinn Jacqueline S. , Spector William D. , Weimer David L. , Mukamel Dana B. 
Published: September 2007

Objective. To assess whether differences in strategic orientation of nursing homes as identified by the Miles and Snow typology are associated with differences in their response to the publication of quality measures on the Nursing Home Compare website.Data Sources. Administrator survey of a national 10 percent random sample (1,502 nursing homes) of all facilities included in the first publication of the Nursing Home Compare report conducted in May–June 2004; 724 responded, yielding a response rate of 48.2 percent.Study Design. The dependent variables are dichotomous, indicating whether or not action was taken and the type of action taken. Four indicator variables were created for each of the four strategic types: Defender, Analyzer, Prospector, and Reactor. Other variables were included in the seven logistic regression models to control for factors other than strategic type that could influence nursing home response to public disclosure of their quality of care.Data Collection/Extraction Methods. Survey data were merged with data on quality measures and organizational characteristics from the first report (November 2002).Principal Findings. About 43 percent of surveyed administrators self‐typed as Defenders, followed by Analyzers (33 percent), and Prospectors (19 percent). The least self‐selected strategic type was the Reactor (6.6 percent). In general, results of the regression models indicate differences in response to quality measure publication by strategic type, with Prospectors and Analyzers more likely, and Reactors less likely, to respond than Defenders.Conclusions. While almost a third of administrators took no action at all, our results indicate that whether, when, and how nursing homes reacted to publication of federally reported quality measures is associated with strategic orientation.

Published: September 2007

Objective.To determine whether late middle‐aged U.S. workers with depression are at an increased risk for retirement.Data Source.Six biennial waves (1992–2002) of the Health and Retirement Study, a nationally representative panel survey of noninstitutionalized 51–61‐year‐olds and their spouses started in 1992.Study Design.Workers aged 53–58 years in 1994 were followed every 2 years thereafter, through 2002. Depression was coded as lagged time‐dependent variables measuring active depression and severity of depression. The main outcome variable was a transition to retirement which was measured using two distinct definitions to capture different stages in the retirement process: (1) Retirement was defined as a transition out of the labor force in the sample of all labor force participants (N=2,853); (2) In addition a transition out of full time work was used as the retirement definition in the subset of labor force participants who were full time workers (N=2,288).Principal Findings.In the sample of all labor force participants, the presence of active depression significantly increased the hazard of retirement in both late middle‐aged men (adjusted OR: 1.37 [95 percent CI 1.05, 1.80]) and women (adjusted OR: 1.40 [95 percent CI 1.10, 1.78]). For women, subthreshold depression was also a significant predictor of retirement. In the sample of full time workers, the relationship between depression and retirement was considerably weaker for women yet remained strong for men.Conclusions.Depression and depressive symptoms were significantly associated with retirement in late middle‐aged U.S. workers. Policymakers must consider the potentially adverse impact of these labor market outcomes when estimating the cost of untreated depression and evaluating the value of interventions to improve the diagnosis and treatment of depression.
When thinking hurts: Attachment, rumination, and postrelationship adjustment
Authors: SAFFREY COLLEEN , EHRENBERG MARION 
Published: September 2007

AbstractThe current study used an attachment framework to explore postrelationship rumination and adjustment. Young adults (N= 231) involved in a romantic relationship that (a) was of 3 months duration or longer and (b) ended in the last 12 months participated in the study. The study assessed rumination generally (brooding, regret, and reflection), and specifically concerning the ended relationship (relationship preoccupation and romantic regret). At the general level, brooding and regret were associated with more negative adjustment, whereas reflection was associated with more positive adjustment. At the relationship level, both relationship preoccupation and romantic regret were associated with more negative adjustment. Models tested indicated that rumination largely mediated the association between attachment anxiety and adjustment.
Empathic accuracy of intimate partners in violent versus nonviolent relationships
Authors: CLEMENTS KAHNI , HOLTZWORTH‐MUNROE AMY , SCHWEINLE WILLIAM , ICKES WILLIAM 
Published: September 2007

AbstractThis study compared the empathic accuracy of men and women who had perpetrated physical intimate partner violence with that of partners in nonviolent but distressed and nonviolent and nondistressed relationships. Examined was the empathic accuracy (a) of partners for one another’s thoughts and feelings during a relationship problem discussion in the laboratory, (b) of partners’ empathic accuracy for each other with the empathic accuracy of objective observers who watched the couples’ interactions, and (c) the males’ empathic accuracy for their female partner to their empathic accuracy for female strangers. No significant group differences were found among women’s empathic accuracy, but the data suggest that violent men exhibit poor empathic accuracy when attempting to understand their female partner’s thoughts and feelings.
From bad to worse: Relationship commitment and vulnerability to partner imperfections
Authors: ARRIAGA XIMENA B. , SLAUGHTERBECK ELIZABETH S. , CAPEZZA NICOLE M. , HMUROVIC JILLIAN L. 
Published: September 2007

AbstractHaving a satisfying romantic relationship is not always feasible, particularly as one discovers less‐than‐perfect partner characteristics. It is suggested that less committed couple members are more vulnerable to negative partner characteristics than are highly committed couple members. Forty‐one dating couples individually indicated their commitment level, were randomly assigned to receive positive‐ or negative‐false feedback about the partner’s personality, and indicated their postmanipulation satisfaction and uncertainty levels. Negative partner feedback affected the satisfaction of less committed but not highly committed individuals. Feeling uncertain about the relationship mediated less committed couple members’ increased vulnerability to negative partner information. The association between uncertainty and commitment was curvilinear and stronger under conditions of relationship threat. Self‐esteem did not predict responses to threat.
Misperception of sexual and romantic interests in opposite‐sex friendships: Four hypotheses
Authors: KOENIG BRYAN L. , KIRKPATRICK LEE A. , KETELAAR TIMOTHY 
Published: September 2007

AbstractTwo online studies evaluated the misperception of sexual and romantic interests in established relationships and tested four hypotheses: a simple sex‐difference hypothesis, a projection hypothesis, a mate value hypothesis, and a mediation hypothesis. Two hundred thirty‐eight (Study 1) and 198 (Study 2) members of young adult opposite‐sex friendship dyads indicated their sexual and romantic interests in their friend and their perceptions of their friend’s sexual and romantic interests in them. Participants projected their own levels of sexual and romantic interests onto their opposite‐sex friend, mediating the following effects: males overperceived and females underperceived their friends’ sexual (but not romantic) interest, and participants of both sexes misperceived the sexual (but not romantic) interest of friends depending on the friends’ mate value.
Attachment style and two forms of affect coregulation between romantic partners
Authors: BUTNER JONATHAN , DIAMOND LISA M. , HICKS ANGELA M. 
Published: September 2007

AbstractThis study examined 2 forms of affect coregulation in 48 cohabiting heterosexual couples who provided daily ratings of positive and negative affect for 21 days. Coregulation was operationalized as covariation in partners’ daily levels of affect and coupling of the rates of change of partners’ affective cycles. Both forms of coregulation were detected, and both were moderated by attachment style. These results are interpreted with respect to the timescales and time courses of each form of coregulation, suggesting that covariation may be more sensitive to discrete affective episodes unfolding during couples’ shared time together, whereas coupling may be a longer term process in which partners manifest sensitivity to one another’s overall patterns of affective fluctuation.
Changes in contact and support exchange in personal networks after widowhood

Published: September 2007

AbstractThe convoy model conceptualizes older adults’ networks of personal relationships as convoys of social support. This prospective study examined how contact and support in several relationships changed due to widowhood. Using observations between 1992 and 2002 from the Longitudinal Aging Study Amsterdam, multilevel models describe change in contact and support of 227 widowed and 408 married older adults. Contact and support were low before widowhood and increased in all relationships after widowhood, and more so in child and sibling relationships. Around 2.5 years after widowhood, contact and support started to decrease. Our findings increase our understanding of the heterogeneity of network changes in old age and of the instability of the network as a social convoy in late life.
Attachment, sexual experience, and sexual pressure in romantic relationships: A dyadic approach
Authors: BRASSARD AUDREY , SHAVER PHILLIP R. , LUSSIER YVAN 
Published: September 2007

AbstractThe goal of this research was to extend the previously documented associations between attachment style and sexual experiences in samples of adolescents and college students to adult couples in committed romantic relationships. A sample of 273 French‐Canadian heterosexual couples aged 18–35 years completed measures of attachment‐related anxiety and avoidance, sexual coercion, and sexual experiences in their relationships. Avoidant attachment was related to two strategies for limiting intimacy in sexual relationships: avoidance of sexual encounters and avoidance of sexual fantasies about one’s partner (the latter for women only). Anxious attachment appeared to interfere with comfortable intimacy, especially among men, who viewed their partner as avoiding sex and who applied more insistent pressure to have sex.
Missionaries, Colonialism and Language in Nineteenth‐Century South Africa
Authors: Gilmour Rachael 
Published: September 2007

AbstractThroughout the nineteenth century, driven by the need both to communicate with potential African converts and to produce written Scriptural translations, Christian missionaries set about studying, transliterating and transforming South African languages. Their work served, in various ways, the demands of the developing British colonial order; established new ‘standard forms’ of South African vernaculars; and facilitated the development of literacy among African people in the region. The close relationship between missionaries, colonialism and language study in South Africa has been documented and analysed by scholars from a wide range of disciplines. This article summarizes some of the key issues in the field, as they have defined critical debates since the 1980s, by focusing on models of ‘invention’ on the one hand and ‘reciprocity’ on the other, and exploring continuities and dissonances between these debates and the wider fields of colonial studies and colonial discourse analysis. It concludes by arguing for a balance. On the one hand, it is vital that we acknowledge the significance of missionary language study as a mode of colonial discourse with the power to shape the social, linguistic, and political realities it purported only to describe. On the other, this should not eclipse our understanding of missionary linguistic work in social context, as the product of fraught, complex, and often mutually transformative encounters between European missionaries and African speakers of the languages in question.
Civil Wars in the Sudan
Authors: Collins Robert 
Published: September 2007

AbstractThis article spans the fifty years of the independent Sudan (1956–2006) during which the country was torn by five civil wars made manifest by the historic marginalization of the Sudanese on the periphery by the powerful riverine Sudanese living in the heartland along the Nile, theawlad al‐bahr(people of the river) and the deep cultural, ethnic, linguistic, and religious differences between those of the center and the periphery that have produced four of the five civil wars. The longest, most violent, and destructive were the two civil wars between the northern and southern Sudanese, the Anya‐Nya civil war, 1963–1972 and the second southern civil war, 1983–2006. Moreover, the second southern civil war experienced from 1991 to 1996 its own internal civil war between the Dinka and Nuer that caused enormous casualties and suffering before the Sudan People's Liberation Army could establish its supremacy. After the military coup détat (June 30, 1989) and the subsequent Islamist revolution, insurgencies erupted both in the East led by the Beja Congress in 1994 and in the West in Darfur by the Sudan Liberation Movement and the Justice and Equality Movement in 2003. The Beja insurgency was settled in 2006 but the disaster in Darfur continues after great loss of life. This article summarizes each of these insurgencies, interprets their ideology, and analyzes the deep tensions which produced them.
Women, Gender and Lordship in France, c.1050–1250
Authors: LoPrete Kimberly A. 
Published: September 2007

AbstractArguing that scholars should follow methods of analysis developed by historians of women in the early Middle Ages and must confront problems in the so‐called ‘Duby thesis’, this article shows how anachronistic analytical categories and insufficient source criticism have masked our appreciation of the extensive political activities of non‐royal aristocratic women in France during the eleventh to thirteenth centuries. Emphasising the domestic context of lordship and political action in this period, as well as the multivalence of gender as an explanatory category, it reveals strong continuities between women's powers in the early and central Middle Ages and shows that female lords were a routine and acceptable part of the medieval French political scene.
Construction of a composite pressure–temperature path: revealing the synorogenic burial and exhumation history of the Sevier hinterland, USA
Authors: HARRIS C. R. , HOISCH T. D. , WELLS M. L. 
Published: September 2007

AbstractMetamorphic pressure–temperature (P–T) paths derived from 16 growth‐zoned garnets, nine from this study and seven from a previous study, have been combined to construct a detailed composite path for an area in the hinterland of the Cretaceous to early Tertiary Sevier orogenic belt in southern Idaho and north‐west Utah. Samples are from two Proterozoic units in the footwall of the Basin‐Elba thrust: the schist of Mahogany Peaks in the central Albion Mountains, Idaho, and the schist of Stevens Spring in the Basin Creek area of the Grouse Creek Mountains, Utah, ∼40 km to the south. The simulated portions of the garnets analysed in this study grew from reactions involving the breakdown of chlorite in the upper greenschist to lower amphibolite facies. Multiple garnets were analysed from three samples. Overlapping segments ofP–Tpaths from different garnets in the same sample correlate with respect to slope and garnet Mn concentration. The compositeP–Tpath documents three episodes of sharply increasing pressures separated by two episodes of pressure decrease, all during progressively increasing temperatures. The path is interpreted to represent alternating episodes of synconvergent thrusting and extensional exhumation in the hinterland of the Sevier orogen. Burial was probably caused by the Basin‐Elba fault, the only major thrust exposed in the region. Extensional exhumation may have occurred along the Mahogany Peaks or Emigrant Spring faults, or by extensional reactivation of the Basin‐Elba fault. This method of correlating partialP–Tpaths to reveal a more complete composite path provides a powerful tool in unveiling orogenic histories in metamorphic terranes, where evidence of major structures responsible for burial and exhumation is commonly obscured by later events.
Zircon U–Pb age and Hf isotope evidence for contrasting origin of bimodal protoliths for ultrahigh‐pressure metamorphic rocks from the Chinese Continental Scientific Drilling project

AbstractA combined study of zircon morphology, U–Pb ages and Hf isotopes as well as whole‐rock major and trace elements was carried out for ultrahigh‐pressure (UHP) eclogite and felsic gneiss from the main hole (MH) of the Chinese Continental Scientific Drilling (CCSD) project in the Sulu orogen. The results show contrasting Hf isotope compositions for bimodal UHP metaigneous rocks, pointing to contrasting origins for their protoliths (thus dual‐bimodal compositions). The samples of interest were from two continuous core segments from CCSD MH at depths of 734.21–737.16 m (I) and 929.67–932.86 m (II) respectively. Zircon U–Pb dating for four samples from the two core segments yields two groups of ages at 784 ± 17 and 222 ± 3 Ma, respectively, corresponding to protolith formation during supercontinental rifting and metamorphic growth during continental collision. Although the Triassic UHP metamorphism significantly reset the zircon U–Pb system of UHP rocks, the Hf isotope compositions of igneous zircon can be used to trace their protolith origin. Contrasting types of initial Hf isotope ratios are, respectively, correlated with segments I and II, regardless of their lithochemistry. The first type shows positive ɛHf(t) values of 7.8 ± 3.1 to 6.0 ± 3.0, with young Hf model age of 1.03 and 1.11 Ga. The second type exhibits negative ɛHf(t) values of −6.9 ± 1.6 to −9.1 ± 1.1, with old Hf model ages of 2.11 and 2.25 Ga. It appears that the UHP rocks from the two segments have protoliths of contrasting origin. Consistent results are also obtained from their trace element compositions suggesting that mid‐Neoproterozoic protoliths of bimodal UHP metaigneous rocks formed during supercontinental rifting at the northern margin of the South China Block. Thus, the first type of bimodal magmatism formed by rapid reworking of juvenile crust, whereas the second type of bimodal magmatism was principally generated by rift anatexis of Paleoproterozoic crust. Melting of orogenic lithosphere has potential to bring about bimodal magmatism with contrasting origins. Because arc–continent collision zones are the best place to accumulate both juvenile and ancient crusts, the contrasting types of bimodal magmatism are proposed to occur in an arc–continent collision orogen during the supercontinental rifting, in response to the attempted breakup of the supercontinent Rodinia at c. 780 Ma.

AbstractPan‐African high‐pressure granulites occur as boudins and layers in the Lurio Belt in north‐eastern Mozambique, eastern Africa. Mafic granulites contain the mineral assemblage garnet + clinopyroxene + plagioclase + quartz ± magnesiohastingsite. Garnet porphyroblasts are zoned with increasing almandine and spessartine contents and decreasing grossular and pyrope contents from core (Alm46Prp32Grs21Sps2) to rim (Alm52Prp26Grs19Sps3). This pattern is interpreted as a retrograde diffusion zoning with the preserved core chemistry representing the peak metamorphic composition. Mineral reaction textures occur in the form of monomineralic and composite plagioclase ± orthopyroxene ± amphibole ± biotite ± magnetite coronas around garnet porphyroblasts. Thermobarometry indicates peak metamorphic conditions of up to 1.57 ± 0.14 GPa and 949 ± 92 °C (stage I), corresponding to crustal depths of ∼55 km. Zircon yielded an U–Pb age of 557 ± 16 Ma, inferred to date crystallization of zircon during peak or immediately post‐peak metamorphism. Formation of plagioclase + orthopyroxene‐bearing coronas surrounding garnet indicates a near‐isothermal decompression of the high‐pressure granulites to lower pressure granulite facies conditions (stage II). Development of plagioclase + amphibole‐coronas enclosing the same garnet porphyroblasts shows subsequent cooling into amphibolite facies conditions (stage III). Symplectitic textures of the corona assemblages indicate rapid decompression. The high‐pressure granulite facies metamorphism of the Lurio Belt, followed by near‐isothermal decompression and subsequent cooling, is in accordance with a long‐lived tectonic history accompanied by high magmatic activity in the Lurio Belt during the late Neoproterozoic–early Palaeozoic East‐African–Antarctic orogeny.
Zircon U–Pb ages and Hf isotope compositions of migmatite from the North Dabie terrane in China: constraints on partial melting

AbstractMigmatite gneisses are widespread in the Dabie orogen, but their formation ages are poorly constrained. Eight samples of migmatite, including leucosome, melanosome, and banded gneiss, were selected for U–Pb dating and Hf isotope analysis. Most metamorphic zircon occurs as overgrowths around inherited igneous cores or as newly grown grains. Morphological and internal structure features suggest that their growth is associated with partial melting. According to the Hf isotope ratio relationships between metamorphic zircon and inherited cores, three formation mechanisms for metamorphic zircon can be determined, which are dissolution–reprecipitation of pre‐existing zircon, breakdown of Zr‐bearing phase other than zircon in a closed system and crystallization from externally derived Zr‐bearing melt. Four samples contain magmatic zircon cores, yielding upper intercept U–Pb ages of 807 ± 35–768 ± 12 Ma suggesting that the protoliths of the migmatites are Neoproterozoic in age. The migmatite zircon yields weighted mean two‐stage Hf model ages of 2513 ± 97–894 ± 54 Ma, indicating reworking of both juvenile and ancient crustal materials at the time of their protolith formation. The metamorphic zircons give U–Pb ages of 145 ± 2–120 ± 2 Ma. The oldest age indicates that partial melting commenced prior to 145 Ma, which also constrains the onset of extensional tectonism in this region to pre‐145 Ma. The youngest age of 120 Ma was obtained from an undeformed granitic vein, indicating that deformation in this area was complete at this time. Two major episodes of partial melting were dated at 139 ± 1 and 123 ± 1Ma. The first episode of partial melting is obviously older than the timing of post‐collision magmatism, corresponding to regional extension. The second episode of partial melting is coeval with the widespread post‐collision magmatism, indicating the gravitational collapse and delamination of the orogenic lithospheric keel of the Dabie orogen, which were possibly triggered by the uprising of the Cretaceous mid‐Pacific superplume.
