Resource connectivity for beneficial insects in landscapes dominated by monoculture tree crop plantations

Homogenization of agricultural landscapes affects ecological processes and biodiversity and can affect the community composition of ecosystem service providers. These effects can have particular impact in landscapes dominated by monocultures of pollinator-dependent tree crop plantations, which create both spatial and temporal homogeneity at the landscape scale. I looked for associations between the proportion of nearby unmanaged vegetation and potential wild pollinator groups collected within flowering almond orchards in two types of landscape. In the Complex landscape, characterized by a heterogeneous mosaic of multiple crops, semi-natural grassland and natural woodland, insect pollinator groups were not associated with unmanaged vegetation. In the Simple landscape, dominated by monoculture almond plantations, most pollinator groups showed positive relationships with the two unmanaged vegetation types (grassland and woodland). In particular, all wild bee and all but one hoverfly individual were found in remnant native vegetation patches within almond plantations, rather than within rows of almond trees. More research is necessary to identify how structural differences created in monoculture landscapes, between crops and the native vegetation they encroach on, influence ecological communities and the provision of ecosystem services.     

Board Independence and Corporate Governance: Evidence From Director Resignations

Abstract:  As is evident from recent changes in NYSE and NASDAQ listing requirements, board independence is assumed to be an important and effective governance mechanism. However, the empirical evidence regarding the value of board independence is mixed. We examine board member resignation announcements and their perceived importance in the context of firms' existing governance structures. We find that outside director resignations appear to send negative signals to market participants. However, this market reaction is less negative when the board is more independent before the departure and when institutional ownership is high, but is more negative for higher levels of officer and director ownership and CEO incentive compensation.     

Image Repair Campaign Strategies Addressing Race: Paula Deen,Social Media,and Defiance

This multi-method study examines how the use of social media in a crisis campaign involving race-related issues may affect a public figure’s credibility and perceived response appropriateness. First, image repair theory is used to analyze Paula Deen’s image repair campaign in the wake of the National Enquirer’s revelation that she admitted to using the “N-word” during a lawsuit deposition. Our analysis shows her response strategies were unsuccessful because her apology did not center on the allegations, and she was contradictory in her bolstering, minimization, and mortification strategies. We build on the Deen case study results by exploring the effectiveness of tweeted message strategies in a race-related crisis via Twitter. We use a mixed-design experiment examining how public figure type (politician v. TV celebrity) and response strategy (moral defense, performance defense, defiance defense, no defense) affect perceptions of a female public figure’s credibility and perceptions of the appropriateness of the response. Results show that any of the three responses are better than no response when addressing charges of racial insensitivity. A defiance defense, as newly tested strategy, and moral defense worked better for the TV celebrity condition than the politician condition. Implications are discussed.     

Facing the gap: exploring research on local knowledge of insect-provided services in agroecosystems

Sustainable agroecosystems must be managed to support biodiversity conservation and food production, which occur at the interface of regional/national policy frameworks, and local knowledge and perspectives. This paper examines the current breadth of research examining farmer knowledge of beneficial insect activities that provide ecosystem services (or benefits) in agroecosystems. We identify patterns and gaps in the literature and opportunities for future research. We found 34 studies that explicitly focused on and documented local knowledge of how insect taxa provided ecosystem services in agroecosystems, the majority of which were immediately observable in farmers’ daily practice: pest control (n?=?26), pollination (n?=?4). We suggest that there is a need for greater investigation of local knowledge of the breadth of ecosystem services provided by insects and identify key research areas that are opportunities for investigation.     

Size of Financing Need and the Choice between Asset Sales and Security Issuances

We study the effect of the size of financing need on a firm's choice between selling assets and issuing securities to finance its investments. The balance sheet effect predicts that a firm prefers to sell assets when the financing need is relatively small as there is less information asymmetry regarding the value of a (small) subset of its assets. When the financing need is large, a firm prefers issuing securities to selling assets. We find evidence supporting the prediction. Our findings remain unchanged when we employ measures of financing need that are relatively independent of the actual amount of financing raised.     

Creating Satisfied Employees Through Workplace Spirituality: A Study of the Private Insurance Sector in Punjab (India)

Spirituality in the workplace is gaining recognition and value among researchers, academicians, and business professionals. The aim of this paper is to examine the impact of spirituality in the workplace on job satisfaction by measuring four dimensions of spirituality in the workplace: meaningful work, sense of community, organizational values, and compassion. The impact of each dimension on job satisfaction is hypothesized. A cross-sectional survey was used to collect data from 100 payroll employees in private insurance companies in Punjab (India). A correlation analysis showed a positive relationship between all the dimensions of spirituality in the workplace and job satisfaction. A regression analysis revealed that although all the dimensions of spirituality in the workplace are important, organizational values and a sense of community are the most important in terms of the job satisfaction level of employees. This work will help insurance companies to better understand the concept of spirituality in the workplace and its importance. Insurance companies can improve their functioning by encouraging employee spirituality in the workplace.     

Two-way relationship between innovation and market structure: evidence from Indian high and medium technology firms

ABSTRACT

This study analyses a two-way relationship between innovation and market structure in Indian high and medium technology firms. We perform an empirical analysis based on a simultaneous equation model on data for 991 high and medium technology firms during 2000–2015. Patent applications and patent grants capture innovation activity of the firms. We find that the market structure has an insignificant impact on innovation. A separate analysis of neck-and-neck firms also suggests that market structure has no impact on innovation. On the other hand, patenting has a positive and significant impact on market structure in both high and medium technology firms. The study concludes that in-house technology creation is a vital source of market dominance in Indian high and medium technology firms.     

Cross‐Country Variability in Cost of Raising Equity: Evidence from Seasoned Equity Offerings

We examine how county‐level governance affects the cost of raising equity. Using data on seasoned equity offerings, we find that the underwriting spread is determined by the litigation risk of issue certifiers, and offer underpricing is largely determined by the investment risk of the equity issue. Underwriting spread increases with enhanced legal enforcement, offsetting the reduction in underpricing associated with strong legal enforcement. Our study offers insight into the effect of legal enforcement and regulatory policy on the cost of raising equity.     

Does early bird catch the worm or a lower GPA? Evidence from a liberal arts college

Research in psychology has shown that early morning classes are not conducive to learning because of the peculiar sleep cycles of adolescents and young adults that cause them to be especially groggy in the morning. Our study examines the relationship between the times that classes are offered and the grades that students in these classes earn at a highly selective liberal arts college. Our main findings are that morning classes are harmful for student achievement. Grades are especially lower for classes that were scheduled at 8 am and 9 am. Moreover, while students of both genders are adversely affected by early morning courses, the effects are particularly pronounced for male students. This institution assigns students randomly to different sections of the same course, thus creating a quasi-natural experiment and enabling us to control for unobserved characteristics of students. In addition, we include student and faculty fixed effects.
