Promises & Partnership

We examine, experimentally and theoretically, how communication within a partnership may mitigate the problem (highlighted in contract theory) of hidden action. What is the form and content of the communication? Which model of decision-making can capture the impact of communication? We consider free-form communication, measure beliefs (about actions and beliefs), and examine which motivational forces influence subjects. We find they harbor belief-dependent preferences that can be captured using psychological game theory. In particular, agents are influenced by guilt aversion, which suggests a theory of why and how communication influences behavior in which statements of intent and resulting expectations play a special role. This has bearing on how to understand partnerships and contracts.Promises; partnership; contract theory; behavioral economics; hidden action; moral hazard; lies; social preferences; psychological game theory; guilt aversion; reciprocity; fairness

Student Perceptions of Enhancing the Internship Experience for Online Principal Preparation Programs

Principal preparation programs understand the need for relevant internship activities that bridge the gap between theory and practice (Anast-May, Buckner, & Geer, 2011; Darling-Hammond, LaPointe, Meyerson, Orr, & Cohen (2007). Principal preparation programs utilizing distance technology are also charged with meeting this expectation and the electronic learning technologies have changed learning from restrictive to flexible, accessible, and innovative (Tseng & Gardner, 2016). The internship is a widely accepted program component of principal preparation that provides the student with actual administrative experience during the certification process; however, despite the mandates from national accreditation organizations and state certification agencies, the literature is replete with criticisms concerning the effectiveness of the internship experience (Cheney & Davis, 2011; Darling-Hammond et al., 2007; Fry, Bottoms, & O’Neill, 2005; Perez et al., 2011). Limited data in the form of student feedback, especially as it pertains to learner perceptions of the internship experience, have been collected (Gordon, Oliver, & Solis, 2016). According to Thiede (2012), it is important for faculty to seek out and study what students are thinking and saying about online education as most higher education institutions’ future enrollments may be predicated upon quality online courses

Mapping plant diversity in cocoa-based agroforestry systems to improve overall productivity

In cocoa-based agroforestry systems (CAFS), the cocoa trees are associated with other cultivated plant species at variable densities. There, the spatial distribution of the cultivated plants can be regular, random or aggregated, and their age may vary even in the same species. Variables of (i) density, (ii) spatial distribution and (iii) age can thus influence the overall productivity of CAFS and its distribution in space. We studied the relationships between these 3 variables and CAFS productivity based on data collected in 34 experimental yield tracking plots placed in agroforestry fields of producers in the Dominican Republic. A mapping of the cultivated plants was carried out on each plot at their installation and harvests of the ripe products of each individual plant were carried out every two weeks over a period of one year. The first results of this study indicate that optimal CAFS productivity can be maintained along a decreasing density gradient of crops, associated with cocoa tree ageing. In addition, regular and random spatial distribution of all plant species may increase overall productivity. The analysis of the variability of cocoa, fruit, tuber and timber yields allows us to provide recommendations on the most suitable species and the optimal distance between plants to improve overall productivity and therefore the producer's income

US Tax Discrimination Against Large Corporations Should Be Discarded

Public opinion holds that large corporations should pay a higher statutory tax rate than other business firms, and enjoy fewer deductions in computing their taxable income. Americans and their representatives in Congress have long entertained the notion that a corporate check paid to the US Treasury means "somebody else" pays the tax, conveniently forgetting that the money has to come from someplace. As the law is now written, the largest corporations (those with assets of $2.5 billion or more) pay about three-fourths of US corporate income taxes, even though they account for just 57 percent of corporate net income. Discriminatory tax burdens on one group of firms drive scarce capital and entrepreneurial energy to less productive firms, penalizing the entire economy. If the targets of discrimination are the nation's largest firms (the norm in the United States) the country will find it harder to compete on a global scale in industries that require dedicated research for decades, industries that exhibit huge scale economies, and industries that network across national borders. Whatever the relative contribution of large and small companies to gross or net job growth, the bottom line for American workers—and the American economy as a whole—is that it is important to ensure that the United States remains a favorable location for US-based multinational corporations to do business.

Laser velocimeter measurements of the flowfield generated by an advanced counterrotating propeller

Results are presented of an investigation to measure the flowfield generated by an advanced counterrotating pusher propeller model similar to the full-scale Unducted Fan demonstrator engine. A laser Doppler velocimeter was used to measure the velocity field in several planes normal to the centerline of the model at axial stations upstream and downstream of each rotor. During this investigation, blades of the F4/A4 type were installed on the model which was operating in a freestream Mach 0.72 regime, with the advance ratio of each rotor set at 2.80. The measured data indicate only a slight influence of the potential field of each front rotor blade on the flowfield upstream of the rotor. The data measured downstream of the front rotor characterize the tip vortices, vortex sheets and potential field nonuniformities generated by the front rotor. The unsteadiness of the flow in the rotating frame of reference of the aft rotor is also illustrated

Admission to psychiatric hospital for mental illnesses 2 years prechildbirth and postchildbirth in Scotland: a health informatics approach to assessing mother and child outcomes

Objective: To identify factors associated with: admission to a specialist mother and baby unit (MBU) and the impact of perinatal mental illness on early childhood development using a data linkage approach in the 2 years prechildbirth and postchildbirth. Methods: Scottish maternity records (SMR02) were linked to psychiatric hospital admissions (SMR04). 3290 pregnancy-related psychiatric admissions for 1730 women were assessed. To investigate factors associated with MBU admission, the group of mothers admitted to an MBU were compared with those admitted to general psychiatric wards. To assess the impact of perinatal mental illness on early child development, a pragmatic indicator for ‘at potential risk of adversity’, defined as a child who was recorded as requiring intensive treatment at any time under the health plan indicators (HPI) and/or who had no record of completing three doses of the 5-in-1 vaccine by 12 months was generated. Logistic regression models were used to describe the association between each variable and the risk of admission between those with a history of prior psychiatric admission and those without. Results Women admitted to an MBU were significantly more likely to be admitted with non-affective psychosis (OR=1.97, 95% CI 1.22 to 3.18), affective psychosis (OR=2.44, 95% CI 1.37 to 4.33) and non-psychotic depressive episodes (OR=1.93, 95% CI 1.42 to 2.63). They were less likely to come from deprived areas (OR=0.68 95% CI 0.49 to 0.93). Women with a previous history of psychiatric admission were significantly more likely to be located in the two most deprived quintiles. Almost one-third (29%) of children born to mothers with a pregnancy-related psychiatric admission were assessed as ‘at potential risk of adversity.’ Conclusions: A health informatics approach has potential for improving understanding of social and clinical factors, which contribute to the outcomes of perinatal mental illness, as well as potential adverse developmental outcomes for offspring
