Meta-analyses of Post-acquisition Performance: Indications of Unidentified Moderators
Empirical research has not consistently identified antecedents for predicting post-acquisition performance. We employ meta-analytic techniques to empirically assess the impact of the most commonly researched antecedent variables on post-acquisition performance. We find robust results indicating that, on average and across the most commonly studied variables, acquiring firms’ performance does not positively change as a function of their acquisition activity, and is negatively affected to a modest extent. More importantly, our results indicate that unidentified variables may explain significant variance in post-acquisition performance, suggesting the need for additional theory development and changes to M&A research methods
Corporate Governance in the Small Firm: Prescriptions for CEOS and Directors
Examinations of boards of directors of smaller corporations have been largely absent from the academic literature. This study addresses this void by examining several aspects of commonly prescribed board configurations for entrepreneurial (high growth) and small (stable growth ) corporations. Specifically, we address board composition and board leadership structure, as well as the impact of officer and director stock holdings and institutional holdings. Stepwise multiple regression analysis reveals that these governance variables significantly add to the explanation of financial performance for both sets of firms. The implications of these findings for Chief Executive Officers (CEOs) and boards of directors are discussed
The Relationship Between Minority Business Enterprises and Corporate Purchasing Personnel: Perceptions from Both Sides of the Table
This paper addresses the nature of the difficulties MBEs face when conducting business with large companies through MBE purchasing programs. Data collected from MBEs and purchasing personnel were analyzed with logistic regression to demonstrate that MBEs and their corporate purchasing counterparts have different perceptions across human, environmental, and organizational dimensions of transaction cost economics. These differences help to explain the problems: (1) that MBEs have in selling to large companies and the problems that MBEs and purchasing personnel have in implementing MBE purchasing programs; (2) of reaching agreement in the marketplace; and, (3) of collectively pursuing the economic development of the minority business community. We offer recommendations for improving the relationship between these parties
Experiences and perceptions of referrals to a community-based physical activity program for cancer survivors: a qualitative exploration
BACKGROUND: Physical activity rates in cancer survivors continue to be low despite the known benefits and availability of evidence-based programs. LIVESTRONG at the Y is a national community-based physical activity program offered cost-free to cancer survivors, though is underutilized. We explored perceptions and experiences of staff and participating survivors to better understand program awareness, referrals and participation.
METHODS: LIVESTRONG at the Y program staff [directors (n = 16), instructors (n = 4)] and survivors (n = 8) from 8 United States YMCAs took part in 30-min semi-structured phone interviews between March-May 2019. Interviews were digitally recorded, transcribed, and evaluated using a thematic analysis approach.
RESULTS: Program staff themes included: 1) Program awareness should be further developed for both the general public and medical providers; 2) Strong relationships with medical providers increased program referrals; 3) Electronic referral systems between providers and LIVESTRONG would help to streamline the referral process; and 4) Bi-directional communication between program staff and medical providers is key to providing patient progress updates. Survivor themes included: 1) Survivors trust their medical team and the information they provide about physical activity; 2) Providers need to incorporate an action plan and referrals for survivors to be active once treatments are completed; and 3) Personal experiences of those who participated in LIVESTRONG resonate with survivors and increase participation.
CONCLUSIONS: LIVESTRONG staff reported the need for an integrated electronic referral system and bi-directional communication with providers about participant progress. Survivors want physical activity education, electronic referrals and follow-up from their healthcare team, coupled with peer support from other survivors. Cancer care provider knowledge and electronic referrals during and after treatment may expedite and increase participation in this community-based program
Written Advice Given by African American Smokers to Their Peers: Qualitative Study of Motivational Messages
BACKGROUND: Although African Americans have the lowest rates of smoking onset and progression to daily smoking, they are less likely to achieve long-term cessation. Interventions tailored to promote use of cessation resources in African American individuals who smoke are needed. In our past work, we demonstrated the effectiveness of a technology-assisted peer-written message intervention for increasing smoking cessation in non-Hispanic White smokers. In this formative study, we have adapted this intervention to be specific for African American smokers.
OBJECTIVE: We aimed to report on the qualitative analysis of messages written by African American current and former smokers for their peers in response to hypothetical scenarios of smokers facing cessation challenges.
METHODS: We recruited African American adult current and former smokers (n=41) via ResearchMatch between April 2017 and November 2017. We asked participants to write motivational messages for their peers in response to smoking-related hypothetical scenarios. We also collected data on sociodemographic factors and smoking characteristics. Thematic analysis was conducted to identify cessation strategies suggested by the study participants.
RESULTS: Among the study participants, 60% (25/41) were female. Additionally, more than half (23/41, 56%) were thinking about quitting, 29% (12/41) had set a quit date, and 27% (11/41) had used electronic cigarettes in the past 30 days. Themes derived from the qualitative analysis of peer-written messages were (1) behavioral strategies, (2) seeking help, (3) improvements in quality of life, (4) attitudes and expectations, and (5) mindfulness/religious or spiritual practices. Under the behavioral strategies theme, distraction strategies were the most frequently suggested strategies (referenced 84 times in the 318 messages), followed by use of evidence-based treatments/cessation strategies. Within the seeking help theme, subthemes included seeking help or support from family/friends or close social networks (referenced 56 times) and health care professionals (referenced 22 times). The most frequent subthemes that emerged from improvements in the quality of life theme included improving one\u27s health (referenced 22 times) and quality of life (referenced 21 times). Subthemes that emerged from the attitude and expectations theme included practicing positive self-talk (referenced 27 times), autonomy/independence from the smoking habit (referenced six times), and financial cost of smoking (referenced five times). The two subthemes that emerged from the mindfulness/religious or spiritual practices theme were use of self-awareness techniques (referenced 36 times) and religious or spiritual practices to cope (referenced 13 times).
CONCLUSIONS: Our approach to adapt a prior peer-message intervention to African American smokers yielded a set of evidence-based messages that may be suitable for smokers at all phases of motivation to quit (ready to quit or not ready to quit). In future research, we plan to assess the impact of texting these messages to African American smokers in a smoking cessation trial.

Goal: 5000-7500 words Currently: 6,465 words (including everything) Exclusive Dealing: Before Bork, and Beyond
Abstract: Antitrust scholars have come to accept the basic ideas about exclusive dealing that Bork articulated in The Antitrust Paradox. Indeed, they have even extended his list of reasons why exclusive dealing can promote economic efficiency. Yet they have also taken up his challenge to explain how exclusive dealing could possibly cause harm, and have modelled a variety of special cases where it does. Some (albeit not all) of these are sufficiently plausible to be useful to prosecutors and judges
Interspecific hybridization between greater kudu and nyala
Hybridization of wildlife species, even in the
absence of introgression, is of concern due to wasted
reproductive effort and a reduction in productivity. In this
study we detail an accidental mating between a female
nyala (Tragelaphus angasii) and a male greater kudu (T.
strepsiceros). The hybrid was phenotypically nyala and
was identified as such based on mitochondrial DNA. Further
genetic analysis based on nine microsatellite markers,
chromosome number and chromosome morphology however,
confirmed its status as an F1 hybrid. Results obtained
from a reproductive potential assessment indicated that this
animal does not have the potential to breed successfully
and can be considered as sterile.http://link.springer.com/journal/10709hb201
Diagnosis of sheep fasciolosis caused by Fasciola hepatica using cathepsin L enzyme-linked immunosorbent assays (ELISA)
Publication history: Accepted - 3 July 2021; Published online - 6 July 2021.Fasciolosis, a global parasitic disease of agricultural livestock, is caused by the liver fluke Fasciola hepatica.
Management and strategic control of fasciolosis on farms depends on early assessment of the extent of disease so
that control measures can be implemented quickly. Traditionally, this has relied on the detection of eggs in the
faeces of animals, a laborious method that lacks sensitivity, especially for sub-clinical infections, and identifies
chronic infections only. Enzyme linked immunosorbent assays (ELISA) offer a quicker and more sensitive
serological means of diagnosis that could detect early acute infection before significant liver damage occurs. The
performance of three functionally-active recombinant forms of the major F. hepatica secreted cathepsins L,
rFhCL1, rFhCL2, rFhCL3, and a cathepsin B, rFhCB3, were evaluated as antigens in an indirect ELISA to serologically
diagnose liver fluke infection in experimentally and naturally infected sheep. rFhCL1 and rFhCL3 were
the most effective of the four antigens detecting fasciolosis in sheep as early as three weeks after experimental
infection, at least five weeks earlier than both coproantigen and faecal egg tests. In addition, the rFhCL1 and
rFhCL3 ELISAs had a very low detection limit for liver fluke in lambs exposed to natural infection on pastures and
thus could play a major role in the surveillance of farms and a ‘test and treat’ approach to disease management.
Finally, antibodies to all three cathepsin L proteases remain high throughout chronic infection but decline
rapidly after drug treatment with the flukicide, triclabendazole, implying that the test may be adapted to trace
the effectiveness of drug treatment.This work was supported by a European Research Council Advanced

Semantic Knowledge Influences Prewired Hedonic Responses to Odors
Background Odor hedonic perception relies on decoding the physicochemical properties of odorant molecules and can be influenced in humans by semantic knowledge. The effect of semantic knowledge on such prewired hedonic processing over the life span has remained unclear. Methodology/Principal Findings The present study measured hedonic response to odors in different age groups (children, teenagers, young adults, and seniors) and found that children and seniors, two age groups characterized by either low level of (children) or weak access to (seniors) odor semantic knowledge, processed odor hedonics more on the basis of their physicochemical properties. In contrast, in teenagers and young adults, who show better levels of semantic odor representation, the role of physicochemical properties was less marked. Conclusions/Significance These findings demonstrate for the first time that the biological determinants that make an odor pleasant or unpleasant are more powerful at either end of the life span
