New Product Announcements as Market Signals. A content analysis in the DRAM chip industry

New-product announcements (NPAs) have considerable effects on competitors in industrial markets. Several studies have shown that the perceived threat caused by an NPA may trigger severe competitive reactions. Yet it is still unclear how the perception of threat by competitors is related to the specific content of the announcement. In this study we explore the actual content of NPAs observed in a particular market. We do this through a multi-year content analysis of new-product announcements in the DRAM memory chip industry. We analyze patterns in the occurrence of attributes and demonstrate how firm strategy affects NPA content. Findings from this study provide important insights for managers about the design of NPAs. It also triggers further research on the use of NPAs in competitive industrial markets.competition;innovation;market signals;new product announcement;semiconductors

Tachtig jaar Marketing

In dit hoofdstuk wordt een schets gegeven van de ontwikkeling van het vakgebied marketing vanaf 1913,het jaar waarin de Nederlandse Handelshogeschool werd opgericht, tot aan dit jaar, 1993, waarin we het zestiende lustrum van de Erasmus Universiteit vieren. Benadrukt wordt het woord "schets": de auteurs zullen hun ideeen geven over marketing in de afgelopen tachtig jaar zoals zij die hebben gevormd door literatuur, overlevering en - voor het laatste gedeelte van deze periode - door eigen waarneming. Er wordt niet gepretendeerd een complete geschiedschrijving van de marketing aan te bieden. Eerst wordt ingegaan op herkomst en ontstaan van marketing. Daarna worden de belangrijkste theoretische invalshoeken die in de loop der tijd binnen marketing zijn gehanteerd besproken, alsmede enkele andere kenmerkende elementen van marketing in haar verdere groei. Tegen deze achtergrond wordt vervolgens aandacht geschonken aan ontwikkelingen in marketing in Nederland en in het bijzonder binnen de jubilerende instelling: de Erasmus Universiteit. Na de bespreking van de ontwikkeling van het vakgebied over de afgelopen tachtig jaar wordt de marketing geschetst zoals die zich in de praktijk heeft afgespeeld bij twee Rotterdamse bedrijven in dezelfde periode. Dit geeft inzicht in de wisselwerking tussen marketingtheorie en marketingpraktijk. Tenslotte worden enkele elementen aangedragen voor het toekomstperspectief van marketing

Neural hypersensitivity to pleasant touch in women remitted from anorexia nervosa.

Interoception, or the sensing and integration of bodily state signals, has been implicated in anorexia nervosa (AN), given that the hallmark symptoms involve food restriction and body image disturbance. Here we focus on brain response to the anticipation and experience of affective interoceptive stimuli. Women remitted from AN (RAN; N = 18) and healthy comparison women (CW; N = 26) underwent a pleasant affective touch paradigm consisting of gentle strokes with a soft brush administered to the forearm or palm during functional neuroimaging. RAN had a lower brain response relative to CW during anticipation of touch, but a greater response when experiencing touch in the right ventral mid-insula. In RAN, this reduced anticipatory response was associated with higher levels of harm avoidance. Exploratory analyses in RAN also suggested that lower response during touch anticipation was associated with greater body dissatisfaction and higher perceived touch intensity ratings. This reduced responsivity to the anticipation of pleasant affective interoceptive stimuli in association with higher harm avoidance, along with an elevated response to the experience of touch, suggests an impaired ability in AN to predict and interpret incoming physiological stimuli. Impaired interoception may thus impact one's sense of self, thereby supporting observations of disturbed body image and avoidance of affective and social stimuli. Therapeutic approaches that help AN to better anticipate and interpret salient affective stimuli or improve tolerance of interoceptive experiences may be an important addition to current interventions

Applying neurobiology to the treatment of adults with anorexia nervosa

BackgroundAnorexia nervosa is a severe, biologically based brain disorder with significant medical complications. It is critical that new, effective treatments are developed to interrupt the persistent course of the illness due to the medical and psychological sequelae. Several psychosocial, behavioral and pharmacologic interventions have been investigated in adult anorexia nervosa; however, evidence shows that their impact is weak and treatment effects are generally small.MethodThis paper describes a new neurobiological anorexia nervosa model that shifts focus from solely external influences, such as social and family, to include internal influences that integrate genetic and neurobiological contributions, across the age span. The model serves as a theoretical structure for a new, five-day treatment, outlined in this paper, targeting anorexia nervosa temperament, which integrates neurobiological dimensions into evidence-based treatment interventions. The treatment is in two phases. Phase I is a five day, 40 hour treatment for anorexia nervosa adults. Phase II is the follow-up and is currently being developed.ResultsPreliminary qualitative acceptability data on 37 adults with anorexia nervosa and 60 supports (e.g., spouses, parents, aunts, friends, partners, children of anorexia nervosa adults) are promising from Phase I. Clients with anorexia nervosa and their supports report that learning neurobiological facts improved their understanding of the illness and helped equip them with better tools to manage anorexia nervosa traits and symptoms. In addition, nutritional knowledge changed significantly.ConclusionsThis is the first neurobiologically based, five-day treatment for adults with anorexia nervosa and their supports. It is a new model that outlines underlying genetic and neurobiological contributions to anorexia nervosa that serves as a foundation to treat both traits and symptoms. Preliminary qualitative findings are promising, with both clients and supports reporting that the neurobiological treatment approach helped them better understand the illness, while better conceptualizing how to respond to their traits and manage their symptoms. Data in Phase I shows promise as a neurobiologically based intervention for anorexia nervosa, and it serves as a foundation for the development of Phase II. Evidence of ongoing program efficacy will be described as data are reported on Phase II.Trial registrationNCT NCT02852538 Registered 1 August 2016

Electronic Theory for the Nonlinear Magneto-Optical Response of Transition-Metals at Surfaces and Interfaces: Dependence of the Kerr-Rotation on Polarization and on the Magnetic Easy Axis

We extend our previous study of the polarization dependence of the nonlinear optical response to the case of magnetic surfaces and buried magnetic interfaces. We calculate for the longitudinal and polar configuration the nonlinear magneto-optical Kerr rotation angle. In particular, we show which tensor elements of the susceptibilities are involved in the enhancement of the Kerr rotation in nonlinear optics for different configurations and we demonstrate by a detailed analysis how the direction of the magnetization and thus the easy axis at surfaces and buried interfaces can be determined from the polarization dependence of the nonlinear magneto-optical response, since the nonlinear Kerr rotation is sensitive to the electromagnetic field components instead of merely the intensities. We also prove from the microscopic treatment of spin-orbit coupling that there is an intrinsic phase difference of 90$^{\circ }$ between tensor elements which are even or odd under magnetization reversal in contrast to linear magneto-optics. Finally, we compare our results with several experiments on Co/Cu films and on Co/Au and Fe/Cr multilayers. We conclude that the nonlinear magneto-optical Kerr-effect determines uniquely the magnetic structure and in particular the magnetic easy axis in films and at multilayer interfaces.Comment: 23 pages Revtex, preprintstyle, 2 uuencoded figure
