Risk perception and adoption of digital innovation in mobile stock trading

An increase in retail investors, trading platforms, and smartphones is facilitating digital transformation in stock trading. Investments in mobile-centered digitalization by trading firms are rapidly becoming a source of competitive advantage. Distinctive psychological aspects involving risks, make stock trading a unique individual decision-making behavior. The objective of the present research is to examine the determinants of retail investors' behavioral intentions (BI) for mobile stock trading (MoST). Across two studies using a mixed method approach we empirically test a framework comprising cognitive risk-mitigation factors, perceived risk (PR), perceived financial cost (PFC), and technology acceptance model (TAM) constructs. The results indicate information quality, privacy, and security protection to mitigate the risk perception involved in trading on mobile platforms. Further, we report the mediation of PR in the relationship between the cognitive risk-mitigating factors and BIs to adopt MoST. Moreover, we find PFC to moderate PR and the TAM constructs' relationship with BIs to adopt MoST. Our research has important theoretical contributions and managerial implications to understand digital adoption behavior by retail investors for MoST platforms.     

The role of consumer ethical beliefs in product‐harm crises

The purpose of this paper is to investigate the consumer reaction during a product‐harm crisis by examining the interdependencies that exist among their ethical beliefs as consumers, their attributions of blame, their feelings of anger and finally their purchase intentions towards the affected company. To test the five research hypotheses, a questionnaire containing a hypothetical crisis scenario of a fictitious company was distributed to 277 consumers. Respondents were asked to read the scenario and answer questions regarding their attribution of responsibility to the company, their feelings of anger and their purchase intentions. In order to investigate consumers' ethical beliefs, a Consumer Ethics Scale was also included in the questionnaire. Structural equation modelling revealed a significant, positive correlation between attributions of blame, anger and ethical beliefs. Moreover, anger negatively affects purchase intentions, whereas the attribution of blame was not found to be significantly connected to purchase intentions. In spite of the rational connection between ethics and crisis, there is lack of research correlating these two concepts. Based on this gap in the literature, the current research attempts to connect ethical beliefs with consumer reactions and emotions during product‐harm crises.

A depictive neural model for the representation of motion verbs

In this paper, we present a depictive neural model for the representation of motion verb semantics in neural models of visual awareness. The problem of modelling motion verb representation is shown to be one of function application, mapping a set of given input variables defining the moving object and the path of motion to a defined output outcome in the motion recognition context. The particular function-applicative implementation and consequent recognition model design presented are seen as arising from a noun-adjective recognition model enabling the recognition of colour adjectives as applied to a set of shapes representing objects to be recognised. The presence of such a function application scheme and a separately implemented position identification and path labelling scheme are accordingly shown to be the primitives required to enable the design and construction of a composite depictive motion verb recognition scheme. Extensions to the presented design to enable the representation of transitive verbs are also discussed.     

Ceftriaxone rescues hippocampal neurons from excitotoxicity and enhances memory retrieval in chronic hypobaric hypoxia

Exposure to high altitude is known to cause impairment in cognitive functions in sojourners. The molecular events leading to this behavioral manifestation, however, still remain an enigma. The present study aims at exploring the nature of memory impairment occurring on chronic exposure to hypobaric hypoxia and the possible role of glutamate in mediating it. Increased ionotropic receptor stimulation by glutamate under hypobaric hypoxic conditions could lead to calcium mediated excitotoxic cell death resulting in impaired cognitive functions. Since glutamate is cleared from the synapse by the Glial Glutamate Transporter, upregulation of the transporter can be a good strategy in preventing excitotoxic cell death. Considering previous reports on upregulation of the expression of Glial Glutamate Transporter on ceftriaxone administration, the therapeutic potential of ceftriaxone in ameliorating hypobaric hypoxia induced memory impairment was investigated in male Sprague Dawley rats. Exposure to hypobaric hypoxia equivalent to an altitude of 7600 m for 14 days lead to oxidative stress, chromatin condensation and neuronal degeneration in the hippocampus. This was accompanied by delayed memory retrieval as evident from increased latency and pathlength in Morris Water Maze. Administration of ceftriaxone at a dose of 200 mg/kg for 7 days and 14 days during the exposure on the other hand improved the performance of rats in the water maze along with decreased oxidative stress and enhanced neuronal survival when compared to hypoxic group without drug administration. An increased expression of Glial Glutamate Transporter was also observed following drug administration indicating faster clearance of glutamate from the synapse. The present study not only brings to light the effect of longer duration of exposure to hypobaric hypoxia on the memory functions, but also indicates the pivotal role played by glutamate in mediating excitotoxic neuronal degeneration at high altitude. The therapeutic potential of ceftriaxone in providing neuroprotection in excitotoxic conditions by increasing Glial Glutamate Transporter expression and thereby enhancing glutamate uptake from the synapse has also been explored.     

The Relatively Happy Fish Revisited

The anecdote of Zhuangzi and Hui Shi's brief discussion on a bridge above the Hao river gives us a nice piece of reasoning in ancient Chinese texts that may serve as a platform for a productive philosophical exchange between the East and the West. The present study examines Hansen's inferential analysis of Zhuangzi and Hui Shi's discussion in this spirit. It is argued that Hansen's analysis founders. To do justice to both Hui Shi and Zhuangzi, the present study proposes that we apply the logic developed in the later Mohist text, the Lesser Pick, to an analysis of their discussion. The re-analysis shows that the intricate dialectic of the reasoning in which Zhuangzi and Hui Shi engage, neatly accords with the pattern of discourse expounded in the Lesser Pick, and gives us global insight into Zhuangzi's final statement in the anecdote, which is notoriously recondite, or confusing.     

Zur Dynamik der Interaktion in der Supervision

The manifold functions of a supervisor in following the course of complex processes together with the trainee, are: ? to keep the goals of the supervision in view, ? to establish a teaching alliance and to support the wish and ambitions of the candidate to learn, ? to build a platform for the complex interactions with the trainee with regard to the dynamics of the training situation and keeping in mind the institutional influences, ? to lay down the setting for the work, ? to explore and to reflect how transference and counter-transference influence the interaction between patient and analyst as well as between trainee and supervisor, ? to examine these interactions together focussing continuously on the interaction between candidate and patient, and to encourage the candidate to do the same on his own, ? to continuously formulate hypotheses about the core conflict, the transference phenomena and resistance of the patient, ? to explore and reflect on the cooperative work.
