Nudging Cooperation in a Crowd Experiment

We examine the hypothesis that driven by a competition heuristic, people don't even reflect or consider whether a cooperation strategy may be better. As a paradigmatic example of this behavior we propose the zero-sum game fallacy, according to which people believe that resources are fixed even when they are not. We demonstrate that people only cooperate if the competitive heuristic is explicitly overridden in an experiment in which participants play two rounds of a game in which competition is suboptimal. The observed spontaneous behavior for most players was to compete. Then participants were explicitly reminded that the competing strategy may not be optimal. This minor intervention boosted cooperation, implying that competition does not result from lack of trust or willingness to cooperate but instead from the inability to inhibit the competition bias. This activity was performed in a controlled laboratory setting and also as a crowd experiment. Understanding the psychological underpinnings of these behaviors may help us improve cooperation and thus may have vast practical consequences to our society.Fil: Niella, Tamara.

Caregivers\u27 perceived factors on barriers and facilitators for participation in SLP telepractice intervention in the satellite centers

This research is a qualitative phenomenological exploratory study using inductive approach. Four (4) participants selected using volunteer sampling were interviewed from the different satellite centers of DLSMHSI via Google Meet. The data gathering procedure was done using key informant interview (KII) provided with forward-backward translations to ensure reliability of questions. A validated interview protocol was used. An interviewer and a live transcriber were present during data gathering and on-the-record transcriptions were done by another researcher who was not present during the interview. Data triangulation was applied to check the accuracy of both transcriptions. Thematic analysis on the responses of the four (4) participants was performed and codes were identified according to the underlying recurrent theme of the responses. Results showed that the caregivers’ perceived facilitators were the caregiver’s knowledge, time management, patient- related factors, session environment and the convenience of services. These themes included the accommodations the satellite center is offering for telepractice sessions. Barriers were time management, patient- related factors and environment, specifically scheduling conflicts, patient’s uncontrollable behaviors, comorbidities and internet problems which affected their participation in the telepractice sessions. Though there were limitations, the current implementation of telepractice in the Philippines is sufficient and beneficial for the caregivers and patients

Efeito de nutrientes combinados com indutores de resistência na proteção contra a vassoura-de-bruxa no cacaueiro Effect of nutrients combined with inducers of resistance on the protection of cocoa seedlings against witches' broom

Na busca por novos indutores de resistência contra a vassoura-de-bruxa no cacaueiro avaliou-se o efeito de vários nutrientes, acibenzolar-S-metil (ASM) e a combinação desses nutrientes com ASM. Os produtos e as misturas foram pulverizados 30 dias antes da inoculação nas mudas do clone SIC-23. Foram utilizados os produtos comerciais Supa-potássio®(silicato de potássio), Hortifós® PK (fosfito de potássio) e Broadacre® Mn (sulfato de manganês), testados nas dosagens 2,5 mL; 5,0 mL; 10 mL/L de água, isoladamente ou combinados com ASM (0,2g/L). O experimento foi conduzido no delineamento de blocos ao acaso, no esquema fatorial, com quatro repetições de doze plantas/parcela. A incidência da doença foi avaliada 60 dias após a inoculação. Somente o ASM promoveu controle significativo da vassoura-de-bruxa. Os nutrientes aplicados isoladamente não apresentaram efeito na severidade da doença. Por outro lado, o efeito protetor do ASM desapareceu quando este foi misturado ao Supa-potássio®, na dose de 5 ou 10 mL/L.<br>Aiming at improving the level of induction of resistance in cocoa, various nutrients, acibenzolar-S-methyl (ASM) and their combination were tested on cocoa seedlings, clone SIC-23, 30 days before inoculation. The commercial products Supa-potássio® (potassium silicate), Hortifós® PK (potassium phosphite) and Broadacre® Mn (manganese sulfate) were sprayed at doses of 2.5, 5.0 mL and 10.0 mL per liter of water, combined or not, with ASM® (0.2 g/L). The experiment was set in a randomized block design, in a factorial scheme, with four replicates of twelve plants each. Disease incidence was assessed 60 days after inoculation. Only ASM promoted significant control of the disease. Nutrients alone had no effect on disease incidence. On the other hand, the protective effect of ASM disappeared when this product was mixed to Supa-potássio at 5 or 10 mL/L
