Foreign body aspiration is a relatively commonly encountered emergency in the pediatric age group. Foreign body can get lodge at any site from supraglottis to the terminal bronchioles. The removal of nasal foreign body in the pediatric age group particularly those lodged posteriorly should always be attempted under general anesthesia as it can dislodge down into the lower airway leading to fata...

The world of applied linguistics and the profession foreign language teaching needs to finally sweep away notion “Native Speaker” (NS) deficit perspective surrounding learners. We argue that Positive Psychology is a source inspiration for new more positive on learners users. Rather than obsessing about negative aspects life, Psychologists defend holistic perspective. By transforming view as fai...

In Evans, Guse, and Honkapohja (2008) the intended steady state is locally but not globally stable under adaptive learning, and unstable deflationary paths can arise after large pessimistic shocks to expectations. In the current paper a modified model is presented that includes a locally stable stagnation regime as a possible outcome arising from large expectation shocks. Policy implications ar...

Free-floating right heart thrombi are uncommon and need emergency treatment in view of their tendency to dislodge and cause pulmonary embolism. We report a successful surgical management of a patient who had large mobile right atrial thrombus, bilateral pulmonary thrombi, coronary artery disease, and postmyocardial infarction ventricular septal rupture (VSR). The patient underwent coronary angi...

Corruption often creates a “briber’s dilemma”: each of the “clients” competing for a rent allocated by a government official has an incentive to pay bribes to try to obtain preferential treatment, but they would all be better off if they could mutually commit not to pay bribes. This paper uses a model of linked games to show how informal relationships among the clients may enable them to enforc...

Hair casts (HCs) are thin, elongated, firm, whitish cylindrical concretions which ensheath the hair shaft and can be easily dislodge. They are of two different types: peripilar and parakeratotic keratin cast. Due to its clinical resemblance to pediculosis capitis, the entity is also known as pseudonits. Al though not unusual, false diagnoses are common, and thus, it is very important to correct...

—The use of automated grape harvesters in the Cape Wine Growing region has resulted in controversy regarding their effect on the chameleon Bradypodion pumilum. We investigated densities of B. pumilum during harvesting at a vineyard near Stellenbosch, South Africa. During dedicated surveys, no chameleons were found in vines, while vegetation surrounding the vines contained densities as high as 1...

Pacemaker twiddler's syndrome is the phenomenon whereby a pacemaker patient may actively dislodge a pacing electrode by manipulating, often unconsciously, the permanent implanted pacemaker. This unusual case is remarkable in several respects: surgical precautions, originally taken to secure the pulse generator against migration, proved ineffective; the displaced lead featured an active fixation...

Due to network effects and switching costs, platform providers often become entrenched. To dislodge them, entrants generally must offer revolutionary products. We explore a second path to platform leadership change that does not rely on Schumpeterian creative destruction: platform envelopment. By leveraging common components and shared user relationships, one platform provider can move into ano...

Many cognitive phenomena of the sort studied by behavioral psychologists show evidence a threshold effect, where certain minimum impulse is required in order to produce change. An example phenomenon preference reversal, change context affects decision, but only if effect on perceived utility sufficiently large. Similar effects play role endowment from owning buying something induces step its va...
