Employment of a Multi-measure Approach as a Vehicle for Monitoring Encoding and Retrieval Dynamics: The Case of Semantically Related Words  [PDF]
Jonathan Guez, Moshe Naveh-Benjamin
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.25072
Abstract: Several recent studies have indicated that retrieval, unlike encoding, is only minimally affected by dividing attention, but is associated with significant secondary task costs. The reported experiment manipulated the strength of pre-experimental semantic associations, using a cued-recall paradigm and a multi-measure approach. This allowed the assessment of accuracy and latency of retrievals, as well as of overall attentional costs and the temporal distribution of attentional costs incurred by these retrievals. By simultaneously inspecting the different measures, we identified a common set of retrieval types and retrieval components. The results presented different patterns for semantically related or un-related words under full or divided attention as a function of the dependent measure used. The results emphasize the advantage of using multi-measure approach to the uncovering of different properties of cognitive processes.

The Asymmetrical Effects of Divided Attention on Encoding and Retrieval Processes: A Different View Based on an Interference with the Episodic Register
Jonathan Guez, Moshe Naveh-Benjamin
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0074447
Abstract: In this study, we evaluate the conceptualization of encoding and retrieval processes established in previous studies that used a divided attention (DA) paradigm. These studies indicated that there were considerable detrimental effects of DA at encoding on later memory performance, but only minimal effects, if any, on divided attention at retrieval. We suggest that this asymmetry in the effects of DA on memory can be due, at least partially, to a confound between the memory phase (encoding and retrieval) and the memory requirements of the task (memory “for” encoded information versus memory “at” test). To control for this confound, we tested memory for encoded information and for retrieved information by introducing a second test that assessed memory for the retrieved information from the first test. We report the results of four experiments that use measures of memory performance, retrieval latency, and performance on the concurrent task, all of which consistently show that DA at retrieval strongly disrupts later memory for the retrieved episode, similarly to the effects of DA at encoding. We suggest that these symmetrical disruptive effects of DA at encoding and retrieval on later retrieval reflect a disruption of an episodic buffer (EB) or episodic register component (ER), rather than a failure of encoding or retrieval operations per se.
Environmental Impact Assessment for an Absorption Heat Transformer  [PDF]
Jorge Avelino Domínguez Pati?o, Antonio Rodríguez Martínez, Rosenberg Javier Romero, Jonathan Ibarra-Bahena, Martha Lilia Domínguez Pati?o
Open Journal of Applied Sciences (OJAppS) , 2016, DOI: 10.4236/ojapps.2016.67042
Abstract: This study presents the environmental impact assessment of an absorption heat transformer designed to recover 1 kW of thermal energy from each 2 kW of waste heat supplies. The net contribution of the heat transformer is a load avoided of 0.665 kg CO2 equivalents; the recovery process avoids 0.729 kg CO2 equivalents and the major contribution to the environment impacts is the pumping process with 0.0437 kg CO2 equivalents for each 1 kWh recovered. The study results show that absorption heat transformer is a good environmental option because it produces useful energy from waste heat and the final result is an environmental impact diminution.
Under the Flag of Blue and White: Mary as an A-NationalSymbol in the Greek-Orthodox Community in Israel  [PDF]
Jonathan Ventura
Sociology Mind (SM) , 2011, DOI: 10.4236/sm.2011.14029
Abstract: Marian devotion and rituals have been the apex of Christian believers’ journey for centuries. In spite of its importance in many disciplines, Marian devotion and rituals in Israel have been neglected. In this article I will outline several social and religious aspects of Marian devotion in the Greek-Orthodox community in Israel. Using several case-studies of Marian devotion around the world I will address the question is Mary a national symbol in Israel? Since one of the most important Marian devotion sites is located in Israel and centered in Mary’s place of ascension in Gethsemane, addressing this site directly is crucial. I will express a new concept more fitting to the Israeli case—Mary as an a-national symbol. This research is based upon a combination of two main methodologies: participant observations and in-depth interviews with believers (local Greek and Palestinian residents as well as pilgrims) and clergymen. The research focuses on a procession taking place in the Old City of Jerusalem in the end of August, celebrating Mary’s legacy and resurrection.
On the Robustness of Strategic Experimentation to Persuasive Cheap Talk  [PDF]
Jonathan Rosborough
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.25097
Abstract: This paper develops a model in which a privately informed seller attempts to indirectly influence the experimentation strategy of a buyer by sending costless signals. The question under consideration is whether there is any credible way in which this single rational seller could influence the buyer’s decisions. We provide bounds on information transmission in equilibrium, and show that there exists no reporting strategy for the seller which changes the experimentation strategy of the buyer. These results demonstrate the robustness of a class of learning models to coercion.
Investor Na?veté and Asset Prices  [PDF]
Jonathan Cook
Journal of Mathematical Finance (JMF) , 2013, DOI: 10.4236/jmf.2013.34047

This paper describes strategic behavior in a nonequilibrium model of asset pricing with heterogeneous sophistication. Both risk and return are increasing in the na?veté of investors in the market. Optimal investment involves in considering the effect that na?e investors have on the market. Further, we derive a simple characterization of the asset price dynamics that results from an arbitrary combination of a countably infinite set of investor types.

Surgery for Acute Stanford Type A Aortic Dissection in an Inner City Community Hospital: Single Surgeon’s Experience  [PDF]
Jonathan Nwiloh
World Journal of Cardiovascular Surgery (WJCS) , 2016, DOI: 10.4236/wjcs.2016.62005
Abstract: Objective: An inverse relationship between volume and mortality in some cardiothoracic surgical procedures has been previously established, leading to suggestions that acute aortic dissection should not be operated in community or low volume heart centers. We therefore reviewed our experience to compare with published data. Methods: Retrospective review of 27 patients who underwent proximal aortic surgery by a single surgeon at an inner city community hospital between May 2004 and April 2015. 16 patients, mean age 51.7 ± 13.6 years old, 75.0% males underwent emergency surgery for acute Stanford type A aortic dissection, while 9 with root or ascending aortic aneurysm, mean age 50.3 ± 15.0 years old, 88.9% males had elective proximal aortic surgery. 2 patients with arch aneurysm were excluded. Results: Four (25.0%) patients with acute dissection were in Penn class A, 3 (18.7%) Penn B, 3 (18.7%) Penn C and 6 (37.5%) Penn B+C. 10 (62.5%) patients underwent emergency root replacement with 60.0% (6/10) mortality all related to malperfusion including 2 patients with bloody stools, while 6 (37.5%) underwent supracoronary graft replacement with 16.6% (1/6) mortality from cardiac tamponade. The 5-year survival was 89.0%. In patients with aortic aneurysm, 8 (88.9%) underwent elective root replacement and 1 (11.1%) supracoronary graft replacement with zero mortality. Conclusion: Supracoronary graft replacement is performed for the majority of uncomplicated acute type A dissections and can be undertaken by the average general cardiac surgeon with acceptable results. Visceral malperfusion especially when associated with bloody stools portends a poor prognosis, and aortic dissection should be excluded in any Marfan patient presenting with acute abdomen. Delaying intervention in attempting transfer to a tertiary hospital can potentially increase preoperative mortality, known to rise with each passing hour from onset of acute dissection. Patients presenting therefore to community hospitals should probably undergo surgery there to avoid complications associated with delay.

Abstract: En el presente trabajo se analiza la jornada laboral nocturna y las implicaciones que ésta tiene en la salud de los trabajadores de una institución que por sus características requiere atención las 24 horas, los siete días a la semana, como lo es la Caja Costarricense del Seguro Social. Para ello se escogió una muestra de médicos, enfermeras y oficiales de seguridad y se les interrogó acerca de las enfermedades que padecían, para tratar de establecer su relación con la jornada nocturna. This paper analyzes the night work and its implications on the health of workers in an institution which by its nature requires 24-hour care, seven days a week, as is La Caja Costarricense de Seguro Social. For this, it was chosen a sample of doctors, nurses and security officers and they were questioned about illnesses they had, to try to establish its relationship with the night shift.
