Canopy CO2 exchange of sugar beet under different CO2 concentrations and nitrogen supply: results from a free-air CO2 enrichment study.

Sugar beet (Beta vulgaris ssp. altissima Döll) was grown in the field under free-air CO(2) enrichment (FACE, 550 ppm) and different nitrogen (N) supply (2001: 126 (N100) and 63 kg.ha(-1) (N50); 2004: 156 (N100) and 75 kg.ha(-1)) during two crop rotations. Canopy CO(2) exchange rates (CCER) were measured during the main growth phase (leaf area index > or =2) using a dynamic chamber system. Canopy CO(2) exchange data were analysed with respect to treatment effects on seasonal means and light use efficiency and light response characteristics. CO(2) enrichment enhanced CCER throughout the season. However, in both years, CCER declined after the second half of August independent of radiation and [CO(2)]. Elevated [CO(2)] strongly stimulated CCER on a seasonal basis, whereas the reduction of CCER caused by low N was below 10% and not significant. There were no effects of N on daily radiation use efficiency of carbon gain calculated from CCER data, but a strong enhancement by CO(2) enrichment. CCER closely tracked diurnal variations in incident photosynthetic photon flux density (PPFD, mumol.m(-2). s(-1)). The relationship between CCER and incident PPFD was curvilinear. In both seasons, initial slopes and maximum rates (CCER(max)) were determined from two 6-day periods using these relationships. The first period was measured after canopy closure (first half of July) and the second in the second half of August. In the first period, elevated [CO(2)] increased the initial slopes. Low N supply affected neither the initial slopes nor their response to elevated [CO(2)] in either period. In contrast to initial slopes, N stress limited the [CO(2)] response of CCER(max) in the first period. In the second period, however, this interaction of [CO(2)] and N on CCER(max) was completely dominated by a general decline of CCER(max) whereas no general decline of the initial slopes occurred in the second period. This response of light response parameters to [CO(2)] and N suggests that, in sugar beet, the decline of CCER in the late season may rely on limiting mechanisms such as photosynthetic acclimation responses to elevated [CO(2)] caused by sink limitations.
Information behavior in stages of exercise behavior change

This study augments the transtheoretical model (TTM) of behavior change with the concepts of information behavior and employs this framework to understand young men's needs for and practices of obtaining and avoiding information on physical activity and exercise in relation to their readiness to change exercise behavior. The results, based on statistical analyses of a population-based survey (N = 616) conducted in Finland, indicate that health information behavior is influenced by an individual′s stage of change in the context of physical activity and exercise. In pre-action stages (precontemplation, contemplation, preparation) where individuals do not exercise regularly and are uninformed or lack motivation, commitment, or skills to change behaviors, information is most often encountered through the passive practice of nondirected monitoring. In the action stage, where individuals have recently changed their exercise behaviors, information is obtained most frequently by active seeking. In the maintenance stage, where individuals maintain earlier adopted behaviors, information is habitually obtained through active scanning. These results support the TTM in its postulation that individuals may benefit from stage-tailored health-communication strategies. The limitations of this study include self-reported behaviors, cross-sectional study design, and a possibly biased sample. Further research is needed to explore the role of information behavior in the process of behavior change in greater detail. © 2012 Wiley Periodicals, Inc.
Exploring Trait Assessment of Samples, Persons, and Cultures

I present a very broad overview of what I have learned about personality trait assessment at different levels and offer some views on future directions for research and clinical practice. I review some basic principles of scale development and argue that internal consistency has been overemphasized; more attention to retest reliability is needed. Because protocol validity is crucial for individual assessment and because validity scales have limited utility, I urge combining assessments from multiple informants, and I present some statistical tools for that purpose. As culture-level traits, I discuss ethos, national character stereotypes, and aggregated personality traits, and summarize evidence for the validity of the latter. Our understanding of trait profiles of cultures is limited, but it can guide future exploration.
Analysis of image search queries on the web: Query modification patterns and semantic attributes

This study investigated query modification patterns and semantic attributes in queries executed during user searches for images on the web. Its purpose was to identify whether query modification patterns were related to users' contextual factors and content sources as well as whether the patterns characterize the use of semantic attributes expressed in users' search queries in an interactive web‐searching process. To this end, a collection of 970 image search queries executed by undergraduate students in a naturalistic setting was analyzed. The study's findings showed that query modification patterns were significantly associated with content sources. Among the types of query modification employed, “Reformulation” and “New” were the most frequently used. Terms related to format, object, or place associated with an image also were found to be frequently used in search queries. Terms referring to type or genre were the most frequent attributes in web image search queries, which suggests a change from previous findings of search queries in a professional context. Implications are discussed in terms of search assistants for web image searches and semantic annotation to improve image indexing.
Drought advances spring growth phenology of the Mediterranean shrub Erica multiflora.

Current climate projections predict drier and warmer conditions in the Mediterranean basin over the next century. While advanced spring growth due to warming has been described in the literature, few data are available on the effects of drought on phenology. Hence, the phenology and growth of two Mediterranean shrubs, Erica multiflora and Globularia alypum, was studied in a rainfall exclusion field experiment to simulate spring drought in a natural shrubland. We estimated the onset of growth in spring by monitoring the appearance of new stems, and the end of growth in summer by following the elongation of stems. Drought treatment caused earlier onset of the spring growing season in E. multiflora, whereas no advance was observed in G. alypum. However, growth cessation was not affected in E. multiflora. Drought reduced the growth of both shrubs, as reflected in less stem elongation. The results show that a drier climate might affect not only growth but also spring phenology of some Mediterranean species. We suggest that a reduction in the cooling effect of transpiration may have analogous effects to warming and might advance the start of growth in E. multiflora, a species whose phenology has been described as warming-sensitive. The lengthening of the growing season resulting from advanced growth did not imply higher productivity, as growth was restricted by drought.
Assessing Adult Attachment Across Different Contexts: Validation of the Portuguese Version of the Experiences in Close Relationships–Relationship Structures Questionnaire

The Experiences in Close Relationships–Relationship Structures questionnaire (ECR–RS) is one of the most recent measures of adult attachment. This instrument provides a contextual assessment of attachment-related anxiety and avoidance by measuring these dimensions in various close relationships (mother, father, partner, friend). To further explore its psychometric properties and cross-cultural adequacy, this study presents the validation of the ECR–RS in a sample of Portuguese community individuals (N = 236). The Portuguese version showed adequate reliability and construct validity. The original 2-factor structure was confirmed through confirmatory factor analysis. The ECR–RS is a psychometrically robust measure of attachment, representing an important advance in the measurement of adult attachment.
Determining the factors that influence college students' adoption of smartphones

This study examines smartphone adoption behavior among American college students by combining all components of innovation diffusion theory (IDT), the technology acceptance model (TAM), the value‐based adoption model (VAM), and the social influence (SI) model. Data indicate that the smartphone adoption rates are beyond the early majority and are now approaching the late majority. The findings of analysis of variance tests revealed that all variables of TAM, VAM, and SI varied across the adopter groups: The current adopter's mean values of the variables were the highest, followed by those of potential and nonadoption groups. Multinomial logistic regression (MLR) analyses revealed that perceived value and affiliation mainly determine the different perceptions of adoption groups. Smartphone adoption, however, was relatively unaffected by perceived ease of use and perceived usefulness. Perceived popularity, perceived price, and ethnicity played a role in distinctive determinants between current adopters and nonadopters. The results imply that adopters perceive smartphones as not only a worthwhile device in which to invest money but also a symbolic device to signal their affiliation and timely technology adoption. Another intriguing finding is the differences of interest in contents between current adopters and nonadopters. Social interactions via social networking services, acquisition for lifestyle, information seeking, and entertainment via gaming were the main applications of interest.
Understanding information and communication technology behavioral intention to use: Applying the UTAUT model to social networking site adoption by young people in a least developed country

According to many studies, social network sites (SNS) have become some of the most popular online destinations. It has been pointed out that very little is known about the psychosocial variables that predict people's use of these websites. In this article, our general objective is to understand behavioral intentions to use SNS employing the well‐known unified theory of acceptance and use of technology (UTAUT), which has been validated in a number of studies. Data were collected through a questionnaire survey from a final sample of 1,039 social networking website users in Africa. We have shown that there are contexts, such as the African context, in which the UTAUT does not hold up. Explanations are provided to support the findings.
Effects of phosphorus availability and genetic variation of leaf terpene content and emission rate in Pinus pinaster seedlings susceptible and resistant to the pine weevil, Hylobius abietis.

We studied the effects of phosphorus fertilisation on foliar terpene concentrations and foliar volatile terpene emission rates in six half-sib families of Pinus pinaster Ait. seedlings. Half of the seedlings were resistant to attack of the pine weevil Hylobius abietis L. , a generalist phloem feeder, and the remaining seedlings were susceptible to this insect. We hypothesised that P stress could modify the terpene concentration in the needles and thus lead to altered terpene emission patterns relevant to plant-insect signalling. The total concentration and emission rate ranged between 5732 and 13,995 μg·g(-1) DW and between 2 and 22 μg·g(-1) DW·h(-1), respectively. Storage and emission were dominated by the isomers α- and β-pinene (77.2% and 84.2% of the total terpene amount amassed and released, respectively). In both resistant and susceptible families, P stress caused an increase of 31% in foliar terpene concentration with an associated 5-fold decrease in terpene emission rates. A higher terpene content in the leaves implies that the 'excess carbon', available under limiting growth conditions (P scarcity), is allocated to terpene production. Sensitive families showed a greater increase in terpene emission rates with increasing P concentrations, which could explain their susceptibility to H. abietis.
Facets of Object Representation: Process and Outcome Over the Course of Psychodynamic Psychotherapy

ABSTRACT This study explores the effectiveness of psychodynamic psychotherapy in improving facets of object relations (OR) functioning over the course of treatment. The sample consisted of 75 outpatients engaged in short-term dynamic psychotherapy at a university-based psychological services clinic. Facets of OR functioning were assessed at pre- and posttreatment by independent raters using the Social Cognition and Object Relations Scale–Global rating method (SCORS–G; Stein, Hilsenroth, Slavin-Mulford, & Pinsker, 2011; Westen, 1995) from in-session patient relational narratives. The Comparative Psychotherapy Process Scale (CPPS; Hilsenroth, Blagys, Ackerman, Bonge, & Blais, 2005) was used to assess therapist activity and psychotherapy techniques early in treatment. Independent clinical ratings of OR functioning and psychotherapy technique were conducted and all were found to be in the good to excellent range of reliability. Specific facets of OR functioning improved with medium to large effect changes posttreatment. These adaptive changes were significantly related to the incidence of psychodynamic-interpersonal (PI) techniques. Also, this study identified the role specific psychodynamic techniques had in facilitating change in a number of underlying dimensions of OR. Patient self-reported reliable change in symptomatology and reliable change in facets of OR were significantly related as well. This study highlights the utility of incorporating psychological assessment into psychotherapy practice to assess change at the explicit (symptoms) and implicit (OR) level. Limitations of this study, future research directions, and implications for clinical practice are discussed.

A Multilevel Analysis of Examinee Gender and USMLE Step 1 Performance

Background To examine the effects of (1) examinee gender on United States Medical Licensing Examination (USMLE) Step 1 performance, (2) examinee gender on the relationships between prematriculation measures and Step 1 performance, and (3) medical school characteristics on the relationships between examinee characteristics and Step 1 performance. Method A series of hierarchical linear models (examinees-nested-in-schools) was conducted predicting Step 1 scores. The sample included 66,412 examinees from 133 U.S. Liaison Committee on Medical Education-accredited medical schools/campuses. Results Controlling for prematriculation measures, men outperformed women slightly on Step 1. Undergraduate science grade point averages were more associated with Step 1 performance for women than men. Schools with higher mean Medical College Admission Test (MCAT) science scores had higher mean Step 1 scores, and MCAT science scores were slightly more associated with Step 1 performance for students from schools with higher percentages of female students. Conclusions Patterns of gender-related performance differences on Step 1 generally mirrored those reported in earlier research. School-level variables provided some additional insight into these relationships, but additional research is needed to fully understand why men and women perform differently on the USMLE.
The Development of the Inventory of Problems–29: A Brief Self-Administered Measure for Discriminating Bona Fide From Feigned Psychiatric and Cognitive Complaints

ABSTRACT This article describes the development of the Inventory of Problems–29 (IOP–29), a new, short, paper-and-pencil, self-administered measure of feigned mental and cognitive disorders. Four clinical comparison simulation studies were conducted. Study 1 (n = 451) selected the items and produced an index of potential feigning. Study 2 (n = 331) scaled this index to produce a probability score, and examined its psychometric properties. Study 3 tested the generalizability of Study 2's findings with 2 additional samples (ns = 128 and 90). Results supported the utility of the IOP–29 for discriminating bona fide from feigned psychiatric and cognitive complaints. Validity was demonstrated in feigning mild traumatic brain injury, psychosis, posttraumatic stress disorder, and depression. Within the independent samples of Studies 2 and 3, the brief IOP–29 performed similarly to the MMPI–2 and Personality Assessment Inventory, and perhaps better than the Test of Memory Malingering. Classifications within these samples with base rates of . 5 produced sensitivity, specificity, positive predictive power, and negative predictive power statistics of about . 80. Further research is needed testing the IOP–29 in ecologically valid field studies.
Understanding review helpfulness as a function of reviewer reputation, review rating, and review depth

This article examines review helpfulness as a function of reviewer reputation, review rating, and review depth. In drawing data from the popular review platform Amazon, results indicate that review helpfulness is positively related to reviewer profile and review depth but is negatively related to review rating. Users seem to have a proclivity for reviews contributed by reviewers with a positive track record. They also appreciate reviews with lambasting comments and those with adequate depth. By highlighting its implications for theory and practice, the article concludes with limitations and areas for further research.
In Vitro Susceptibility Rhythms. II. Biological-Time-Dependent Differences in Effect of βr and β2-Adrenergic Agonists of Rat Aorta and Influence of Endothelium

Time-dependent variations in the vasodilator effects of β-adrenergic agonists terbutaline (Ter) and dobutamine (Dob) were studied in isolated rings of rat thoracic aorta in both endothelium-intact and endothelium-de-nuded preparations. Rats were housed in light from 08: 00 to 20: 00 and in darkness from 20: 00 to 08: 00 and sacrificed at six different times of the day. In endothelium-intact and endothelium-denuded aortic rings precontracted submaximally with phenylephrine (Phe), addition of Ter and Dob produced concentration-dependent relaxations. Removal of endothelium reduced the relaxant responses and area under curve (AUC) values and augmented the EC50 values to Ter and Dob at most, but not all, time points. Two-way analysis of variance (ANOVA) revealed that AUCs, maximum responses, and EC50values significantly depended on both treatment (endothelium intact/endothe-lium denuded) and time of sacrifice. Results of the present study clearly show that in vitro sensitivity of rat thoracic aorta to P-adrene.
Clinician-Guided Assessment of Personality Using the Structural Interview and the Structured Interview of Personality Organization (STIPO)

ABSTRACT This article demonstrates the utility of a theory-guided psychodynamic approach to the assessment of personality and personality pathology based on the object relations model developed by Kernberg (1984). We describe a clinical interview, the Structural Interview (SI; Kernberg, 1984), and also a semistructured approach, the Structured Interview of Personality Organization (STIPO; Clarkin, Caligor, Stern, & Kernberg, 2004) based on this theoretical model. Both interviews focus on the assessment of consolidated identity versus identity disturbance, the use of adaptive versus lower level defensive operations, and intact versus loss of reality testing. In the context of a more clinically oriented assessment, the SI makes use of tactful confrontation of discrepancies and contradictions in the patient's narrative, and also takes into account transference and countertransference phenomena, whereas the more structured approach of the STIPO incorporates clinical judgment informed by clinical theory into a well-guided interaction with the patient. Both interviews have good interrater reliability and are coherent with the alternative model for personality disorder diagnosis proposed by the Diagnostic and Statistical Manual of Mental Disorders (5th ed.), Section III. Finally, they provide the clinician with specific implications for prognosis and treatment planning and can rationally guide clinical decision making.
Why We Need a Formal Systematic Approach to Validating Psychological Tests: The Case of the Rorschach Comprehensive System

ABSTRACT This article documents and discusses the importance of using a formal systematic approach to validating psychological tests. To illustrate, results are presented from a systematic review of the validity findings cited in the Rorschach Comprehensive System (CS; Exner, 2003) test manual, originally conducted during the manuscript review process for Mihura, Meyer, Dumitrascu, and Bombel's (2013) CS meta-analyses. Our review documents (a) the degree to which the CS test manual reports validity findings for each test variable, (b) whether these findings are publicly accessible or unpublished studies coordinated by the test developer, and (c) the presence and nature of data discrepancies between the CS test manual and the cited source. Implications are discussed for the CS in particular, the Rorschach more generally, and psychological tests more broadly. Notably, a history of intensive scrutiny of the Rorschach has resulted in more stringent standards applied to it, even though its scales have more published and supportive construct validity meta-analyses than any other psychological test. Calls are made for (a) a mechanism to correct data errors in the scientific literature, (b) guidelines for test developers' key unpublished studies, and (c) systematic reviews and meta-analyses to become standard practice for all psychological tests.
