IT-Driven Organizational Identity Change: A Longitudinal Inquiry

While organizational scholars are increasingly interested in issues of identity, in-depth empirical studies analyzing the actual process of identity change have lagged, particularly when the process is triggered by IT-related transformational change (Alvesson et al. 2008). In this longitudinal case study, we follow the identity change process of librarians following the digitization of their work environment. We use segments of Hatch & Schultz‟s (2002) organizational identity dynamics model to uncover the provisional identities experienced by librarians over time. We also illustrate how the librarians‟ image, as mirrored by the patrons, led the librarians to put forward initiatives to impress on the patrons ideas of “who they were” and “who they could be.” This duality is explained by the ambiguous nature of information technology, which can be interpreted as both an opportunity and a threat concurrently

AN INVESTIGATION OF PRINCIPAL LEADERSHIP BEHAVIORS AND IMPLEMENTATION OF ADULT LEARNING STRATEGIES ON THE PROFESSIONAL LEARNING ENVIRONMENT OF A K-12 SCHOOL

The purpose of this quantitative study was to explore the influence of principal leadership behaviors and potential of utilizing adult learning strategies on the development of a school’s professional learning environment (PLE). The intention was also to determine if principals considered themselves prepared to develop and sustain such an environment. Research shows that principals and teachers perceive professional development needs and results differently. To obtain perspective from both groups, two separate surveys were administered. The results from this dissertation came from 262 principals and 433 teachers employed in K-12 public schools in Indiana. With the survey completed by principals, the focus was to determine if principals considered themselves prepared to be leaders of adult learners and well adept at developing a school PLE. Efficacy in developing and sustaining a PLE as well as efficacy in andragogical practices were analyzed to determine if they could result in a variance in a school’s professional learning environment. The survey completed by teachers focused on teacher perception of principal leadership behaviors and the use of adult learning strategies. The impact of a principal’s leadership behaviors and use of adult learning strategies were analyzed to determine if the two variables could result in the variance in a school’s professional learning environment. Results of the study found that there is a perceived need for additional training for principals in developing a PLE as well as understanding more about adult learning theory. Additionally, this research suggests that efficacy in professional learning environment and efficacy in adult learning strategies influence a school’s professional learning environment. iv Upon analysis of data provided by teachers, this dissertation concludes that principal leadership behaviors and implementation of adult learning strategies also influences a school’s professional learning environment. The purpose of this research is to provide possible insight into specific behaviors and practices that may support the development and sustainability of a professional learning environment and that this information can also be used to encourage and support future principal development

Stories: A Revision of the Willingness & Action Measure for Children and Adolescents (WAM-C/A)

In its earliest stages, acceptance and commitment therapy (ACT; Hayes, Strosahl, & Wilson, 1999) with youths appears to be a promising therapeutic approach. Experiential willingness and committed action are two foci of ACT, making their assessment an integral part of therapy. Field tests have found validity problems with the Willingness and Action Measure for Children and Adolescents (WAM-C/A). The current study utilized the Story Version of the Willingness and Action Measure for Children and Adolescents (SWAM-C/A). Results supported the relationship between the SWAM-C/A and measures of experiential avoidance and mindfulness. Factor analysis indicated the presence of several distinct willingness and action factors. These results support the need for continued work on measurement of willingness and action in youth

Forest therapy can prevent and treat depression: Evidence from meta-analyses

Forest therapy involves engaging in a combination of forest-based activities to improve one’s health or wellbeing. We conducted an overview of systematic reviews (SRs) and meta-analyses of primary studies to provide the most comprehensive summary of the effect of forest therapy on depression. We included 13 primary studies that matched our eligibility criteria - all were included in four recent SRs and were conducted in the Republic of Korea. We carried out meta-analyses with data extracted directly from these 13 studies and assessed their risk of bias. Outcomes of interest were depressive symptoms, temporary recovery from depression (i.e. remission), response to treatment (i.e. ≥ 50 % reduction on depressive symptoms from baseline), adherence to treatment, and adverse effects. Considering pooled estimates from randomized controlled trials with adults, we found that compared to no intervention/usual care, forest therapy produced a greater reduction of depressive symptoms (Hedges’g = 1.18, 95 % CI [0.86, 1.50], p < .00001). Also compared to no intervention/usual care, participants in the forest therapy group were 17 times as likely to achieve remission (Risk Ratio = 17.02, 95 % CI [3.40, 85.21], p = .0006) and three times as likely to have a ≥ 50 % reduction on depressive symptoms (Risk Ratio = 3.18, 95 % CI [1.94, 5.21], p < .00001). Forest therapy, on average, reduced depressive symptoms more than engaging in similar activities in a hospital or non-forested urban area, or participating in an intervention focused on diet plus forest-based exercise. We did not find evidence that adherence to forest therapy is different from the adherence to alternative interventions and the adverse effects of forest therapy appear to be rare. These results indicate that, relative to many more conventional alternatives, forest therapy is a more effective short-term intervention for the prevention and treatment of depression in adults

Vaginal support as determined by levator ani defect status 6 weeks after primary surgery for pelvic organ prolapse

ObjectiveTo evaluate whether major levator ani muscle defects were associated with differences in postoperative vaginal support after primary surgery for pelvic organ prolapse (POP).MethodsA retrospective chart review of a subgroup of patients in the Organ Prolapse and Levator (OPAL) study. Of the 247 women recruited into OPAL, 107 underwent surgery for prolapse and were the cohort for the present analysis. Major levator ani defects were diagnosed when more than 50% of the pubovisceral muscle was missing on MRI. Postoperative vaginal support was assessed via POPâ quantification system. Postoperative anatomic outcome was analyzed according to levator ani defect status, as determined by MRI.ResultsSupport of the anterior vaginal wall 2 cm above the hymen occurred among 62% of women with normal levator ani muscles/minor defects and 35% of those with major defects. Support of the anterior wall 1 cm above the hymen occurred among 32% women with normal muscles /minor defects and 59% of those with major defects. Levator ani defects were not associated with differences in postoperative apical/posterior vaginal support.ConclusionSix weeks after primary surgery for prolapse, women with normal levator ani muscles/minor defects had better anterior vaginal support than those with major levator defects.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135557/1/ijgo141.pd

Measurements of Forbush decreases at Mars: both by MSL on ground and by MAVEN in orbit

The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) Curiosity rover, has been measuring ground level particle fluxes along with the radiation dose rate at the surface of Mars since August 2012. Similar to neutron monitors at Earth, RAD sees many Forbush decreases (FDs) in the galactic cosmic ray (GCR) induced surface fluxes and dose rates. These FDs are associated with coronal mass ejections (CMEs) and/or stream/corotating interaction regions (SIRs/CIRs). Orbiting above the Martian atmosphere, the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft has also been monitoring space weather conditions at Mars since September 2014. The penetrating particle flux channels in the Solar Energetic Particle (SEP) instrument onboard MAVEN can also be employed to detect FDs. For the first time, we study the statistics and properties of a list of FDs observed in-situ at Mars, seen both on the surface by MSL/RAD and in orbit detected by the MAVEN/SEP instrument. Such a list of FDs can be used for studying interplanetary CME (ICME) propagation and SIR evolution through the inner heliosphere. The magnitudes of different FDs can be well-fitted by a power-law distribution. The systematic difference between the magnitudes of the FDs within and outside the Martian atmosphere may be mostly attributed to the energy-dependent modulation of the GCR particles by both the pass-by ICMEs/SIRs and the Martian atmosphere

Timing of Moderate Level Prenatal Alcohol Exposure Influences Gene Expression of Sensory Processing Behavior in Rhesus Monkeys

Sensory processing disorder, characterized by over- or under-responsivity to non-noxious environmental stimuli, is a common but poorly understood disorder. We examined the role of prenatal alcohol exposure, serotonin transporter gene polymorphic region variation (rh5-HTTLPR), and striatal dopamine (DA) function on behavioral measures of sensory responsivity to repeated non-noxious sensory stimuli in macaque monkeys. Results indicated that early gestation alcohol exposure induced behavioral under-responsivity to environmental stimuli in monkeys carrying the short (s) rh5-HTTLPR allele compared to both early-exposed monkeys homozygous for the long (l) allele and monkeys from middle-to-late exposed pregnancies and controls, regardless of genotype. Moreover, prenatal timing of alcohol exposure altered the relationship between sensory scores and DA D2R availability. In early-exposed monkeys, a positive relationship was shown between sensory scores and DA D2R availability, with low or blunted DA function associated with under-responsive sensory function. The opposite pattern was found for the middle-to-late gestation alcohol-exposed group. These findings raise questions about how the timing of prenatal perturbation and genotype contributes to effects on neural processing and possibly alters neural connections

Structure and magnetic property of potassium intercalated pentacene: observation of superconducting phase in KxC22H14

We report the results from systematic investigations on the structure and magnetic properties of potassium intercalated pentacene as a function of potassium content, K x C22H14 (1  ≤  x  ≤  3). Synchrotron radiation powder x-ray diffraction technique revealed that there are two different stable phases can be obtained via potassium intercalation, namely, K1C22H14 phase and K3C22H14 phase. Structural phase transition was induced when the potassium content was increased to the nominal value x  =  3. This phase transition is accompanied by drastic change in their magnetic property, where those samples with compositions K1C22H14 shows ferromagnetic behavior and those with near K3C22H14 lead to observation of superconductivity with transition temperature, T c, of 4.5 K. It is first time that superconductivity was observed in linear oligoacenes. Both magnetization study and synchrotron radiation powder x-ray diffraction clearly indicates that the superconducting phase belong to K3C22H14 as a result of phase transition from triclinic to monoclinic structure induced by chemical doping
