The Desires to Work for an Organizational Culture Type Based on Personality Characteristics and Gender
Finding a company to work for is a two-way street in that a job applicant must like the company and the company must like the applicant. Job applicants and hiring companies both want to find a mutual fit. This fit can potentially be observed through the personality characteristics and gender of the applicant as well as the organizational culture type of the company. The purpose of this study is to understand how individuals view an organizational culture and have the desire to work for an organizational culture type based on individuals’ personality characteristics and gender
Description of embryonic development of Atka mackerel (Pleurogrammus monopterygius)
Atka mackerel (Pleurogrammus monopterygius) is hexagrammid fish that inhabits the temperate and subarctic North Pacific Ocean and neighboring seas (Fig. 1). This highly
abundant fish is a critically important prey species (Sinclair and Zeppelin, 2002; Zenger, 2004) that supports
a directed commercial trawl fishery (Lowe et al., 2006). Atka mackerel is a demersal spawner and males provide
parental care to eggs (Zolotov, 1993). During breeding periods, sexually mature males aggregate on the bottom at nesting sites where they establish territories (Lauth et al., in press). Sexually mature females periodically visit male nesting territories from July to October to spawn batches of demersal egg masses (McDermott and Lowe, 1997; McDermott et al., 2007). Individual nests may consist
of multiple egg masses deposited by different females, and males defend nesting territories for a protracted period lasting from the time territories are being established until all eggs within the territory are completely hatched (Lauth et al., 2007). Knowledge about the timing of the
reproductive cycle and the use of spawning habitat are important for understanding population structure and the dynamics of stock recruitment, which in turn are important
factors in the management of Atka mackerel populations
Effects of Gear Modifications on the Trawl Performance and Catching Efficiency of the West Coast Upper Continental Slope Groundfish Survey Trawl
Since 1984, annual bottom trawl surveys of the west coast (California–Washington) upper continental slope (WCUCS) have provided information on the abundance, distribution, and biological characteristics of groundfish resources.
Slope species of the deep-water complex (DWC) are of particular importance and include Dover sole, Microstomus pacificus; sablefish, Anoplopoma fimbria; shortspine
thornyhead, Sebastolobus alascanus; and longspine thornyhead, S. altivelis. In the fall of 1994, we conducted an experimental gear research cruise in lieu of our normal survey because of concerns about the performance of the survey trawl. The experiment was conducted on a soft mud bottom at depths of 460–490 m off the central Oregon coast. Treatments included different combinations of door-bridle rigging, groundgear weight, and scope length. The experimental design was a 2 ´ 2 ´ 2 factorial within a randomized complete-block. Analysis of variance was used to examine the effects of gear modifications on the engineering
performance of the trawl (i.e. trawl dimensions, variation in trawl dimensions, and door attitude) and to determine if catch rates in terms of weight and number of DWC species and invertebrates were affected by the gear modifications. Trawl performance was highly variable for the historically used standard trawl configuration. Improvements were observed with the addition of either a 2-bridle door or lighter ground gear. Changes in scope length had relatively little effect on trawl performance. The interaction of door bridle and ground gear weight had the most effect on trawl performance. In spite of the standard trawl’s erratic performance, catch rates of all four DWC species and invertebrates were not significantly different than the 2-bridle/heavy combination, which did the best in terms of engineering performance. The most important factor affecting DWC catch rates was ground gear. Scope length and the type of door bridle had little effect on DWC catch
rates. Subsequent revisions to survey gear and towing protocol and their impact on the continuity of the slope survey time series are discussed
Forward Diffracted Parametric X Radiation From a Thick Tungsten Single Crystal at 855 MeV Electron Energy
Features of forward diffracted Parametric X-Radiation (PXR) were investigated
at experiments with the 855 MeV electron beam of the Mainz Microtron MAMI
employing a 410 micrometer thick tungsten single crystal. Virtual photons from
the electron field are diffracted by the (10-1) plane at a Bragg angle of 3.977
degree. Forward emitted radiation was analyzed at an energy of 40 keV with the
(111) lattice planes of a flat silicon single crystal in Bragg geometry. Clear
peak structures were observed in an angular scan of the tungsten single
crystal. The results were analyzed with a model which describes forward
diffracted PXR under real experimental conditions. The experiments show that
forward diffracted PXR may be employed to diagnose bending radii of lattice
planes in large area single crystals
Attention Deficit Disorder and Memory Capacity in Language-impaired and Inconspicuous Children
Ausgehend von der Hypothese einer geringeren Gedächtnisfähigkeit sprachauffälliger Kinder wurden 110 sprachauffällige und 123 sprachunauffällige Kinder im Grundschulalter (Altersdurchschnitt 10;0 Jahre) untersucht. Die Kinder absolvierten jeweils einzeln einen verbalen Gedächtnistest sowie einen Test zur Problemlösereflexivität. Ferner beurteilten die Lehrer ihre Schüler im Hinblick auf Aufmerksamkeitsstörungen und Aufmerksamkeitsverhalten. Im Ergebnis zeigen sich signifikante Unterschiede zwischen beiden Gruppen in bezug auf die Gedächtnisfähigkeit und die Anzahl der Fehler. Den sprachauffälligen Schülern gelingt es weniger gut, Wortlisten zu lernen und den Lerngewinn gegen eine Ablenkung aufrechtzuerhalten. Sie weisen eine signifikant geringere Behaltensstabilität auf. Die Gedächtnisfähigkeit ist ferner weitgehend unabhängig von der Problemlösereflexivität und dem im Lehrerurteil festgehaltenen Aufmerksamkeitsverhalten. Es wird geschlossen, daß sprachauffällige Kinder sowohl Schwierigkeiten bei der Informationsaufnahme als auch Einschränkungen der Gedächtniskapazität haben. Die unterschiedliche Gedächtnisfähigkeit von sprachauffälligen und sprachunauffälligen Kindern ist am ehesten durch die (meta)kognitiven Kompetenzen der Kinder erklärbar.(DIPF/Orig.)In order to investigate the hypothesis that language-impaired children also show deficits in memory, 110 language-impaired and 123 children showing no such impairments (average age 10;0 yrs.) were tested for verbal memory and selecting attention through a matching familiar figures test. As an additional measure, teachers assessed the children, using DSM criteria, for both general attentivenesse and attention deficit disorder. The results revealed significant differences between both groups concerning their ability to memorise word lists and difficulties resisting distractions. They also show a significantly diminished stability regarding the retention of memories. Furthermore, the ability to memorise has proved to be greatly independent of both selective attention and the rated attentiveness in class. It is therefore concluded that language-impaired children have difficulties in acquiring information as well as a limited capacity to memorise. These differences in ability to memorise between language-impaired children and children with no impairments are most likely attributable to the meta-cognitive competence of the child.(DIPF/Orig.

Í þessari yfirlitsgrein er lýst gagnreyndri meðferð við ÁÞR meðal barna og unglinga. Leitað var í PubMED að öllum samanburðarrannsóknum, yfirlitsgreinum og klínískum leiðbeiningum. Hugræn atferlismeðferð (HAM) og sérhæfð serótónín-endurupptökuhamlandi lyf (SSRI) eru áhrifarík með- ferðarform fyrir börn og unglinga sem koma fyrsta sinn í meðferð. Í samanburðarrannsóknum hefur HAM vinninginn. Rannsóknir á börnum sem svara fyrstu meðferð illa eru takmarkaðar en benda þó til þess að áframhaldandi HAM og SSRI séu áhrifarík úrræði fyrir þá sem ekki svara HAM en HAM+SSRI sé áhrifaríkasta úrræðið fyrir þá sem ekki svara SSRI og hafa aldrei verið meðhöndlaðir með HAM. Fyrri rannsóknir eru í samræmi við klínískar leiðbeiningar þar sem fyrsta úrræði er HAM þegar aðgengi að kunnáttumönnum í HAM er til staðar. HAM er einnig jafn árangursríkt og SSRI hjá þeim sem enn hafa talsverð einkenni eftir 14 vikur. Niðurstöður bentu ekki til þess að HAM+SSRI sé áhrifaríkara en HAM veitt af sérfræðingum. HAPediatric obsessive-compulsive disorder (OCD) is characterized by recurrent obsessions and compulsions. In this review we depict evidence- -based treatments for pediatric OCD patients. We searched PubMed for relevant publications including randomized controlled trials, reviews, and expert guidelines. Substantial evidence for cognitive behavior therapy (CBT) and specific serotonin reuptake inhibitors (SSRIs) among treatment-naïve patients shows that both treatments are effective. CBT is significantly more effective than SSRI based on head-to-head trials. The evidence for CBT- or SSRI-resistant patients is limited but indicates that CBT and SSRI are effective treatments for CBT non-responders while a combination of CBT and SSRI is the most effective treatment for SSRI non-responders with no prior exposure to CBT. The current data support clinical guidelines indicating that when CBT expertise is present, one can successfully treat patients with CBT. CBT is also as effective as SSRI in non-responders after 14 weeks of CBT. The results did not indicate that combined treatment of CBT and SSRI is more effective than CBT delivered by experts. However, combined treatment is more effective than SSRI in SSRI non-responder
