Family- Owned Business Leader Succession Planning Strategies
AbstractSome business leaders in family-owned businesses lack leadership succession planning strategies. Family-owned businesses that lack succession planning strategies decrease the likelihood of business sustainability after the transition from founder to the successor. Grounded in the socioemotional wealth theory, the purpose of this qualitative multiple case study was to explore succession planning strategies first-generation family-owned business leaders in the metro Atlanta, Georgia area used to transfer leadership and ownership to the second generation. Data collected for this study consisted of semistructured interviews via teleconferences, company website information, press releases, and internal company documents. Yin’s 5 step process was used to analyze the data. Five themes emerged from the data analysis: successor factors, family factors, leader factors, transition factors, and next-generation succession planning factors. A key recommendation is for leaders of family-owned businesses to develop a succession plan that takes into account the non-economic aspects of the family firm in addition to the financial aspects. The implication for positive social change includes equipping leaders of family-owned businesses with strategies that may improve family business sustainability rates from generation to generation leading to growth and development opportunities within the firm and the community where the firm conducts its business
Organizational Mortality of Small Firms: The Effects of Entrepreneurial Age and Human Capital
This paper addresses the issue of internal determination of organizational outcomes. It is argued that in small and simply structured organizations a considerable proportion of the variance in organizational activities and outcomes is associated with individuals. In particular, the paper uses human capital theory to derive hypotheses about individual determinants of organizational mortality. These hypotheses are tested with event-history data of firm registrations and de-registrations in a West German region. The hypotheses are corroborated by the data, but the effects may nonetheless be due to processes linking individual characteristics with organizational performance other than those suggested by the human capital approach
Mitochondrial protein p26 BCL2 reduces growth factor requirements of NIH3T3 fibroblasts
The BCL2 (B cell lymphoma/leukemia-2) proto-oncogene encodes a 26-kDa protein that has been localized to the inner mitochondrial membrane and that has been shown to enhance the survival of some types of hematopoietic cells. Here we show that NIH3T3 fibroblasts stably transfected with a BCL2 expression plasmid exhibit reduced dependence on competence-inducing growth factors (platelet-derived growth factor, PDGF; epidermal growth factor, EGF) for initiation of DNA synthesis. The importance of BCL2 for growth factorinduced proliferation of these cells was further confirmed by the useage of BCL2 antisense oligodeoxynucleotides. The mechanisms by which overexpression of p26 BCL2 contributes to fibroblast proliferation are unknown, but do not involve alterations in: (a) the production of inositol triphosphates (IP3), (b) PDGF-induced transient elevations in cytosolic Ca2+ ions, or (c) the activity of protein kinase C enzymes in these transfected cells. The results imply that changes in mitochondrial functions play an important role in the early stages of the cell cycle that render 3T3 cells competent to respond to the serum progression factors that stimulate entry into S-phase.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29195/1/0000249.pd
Exercise and pregnancy in recreational and elite athletes: 2016 evidence summary from the IOC expert group meeting, Lausanne. Part 1-exercise in women planning pregnancy and those who are pregnant
BACKGROUND Guidelines on physical activity or exercise and pregnancy encourage pregnant women to continue or adopt an active lifestyle during and following pregnancy.1-3 Two systematic reviews of pregnancy-related guidelines on physical activity found similarities between recommendations from different countries, but noted that the guidelines differed in focus.4 5 The guidelines provided variable guidance on prenatal exercise, or on how pregnant women might approach continuing or adopting sport activities.6 However, most guidelines did not include important topics such as prevalence and known risk factors for common pregnancy-related diseases and complaints, and the role of exercise in preventing and treating them. Importantly, the focus of most previous guidelines has been on healthy pregnant women in the general population, in whom there is almost always a decline in physical activity during pregnancy.7 8 Indeed, a high proportion of pregnant women follow neither physical activity nor exercise guidelines, 9 putting them at increased risk of obesity, gestational diabetes mellitus (GDM), and other pregnancy-related diseases and complaints.1 On the other hand, there are enthusiastic exercisers and elite athletes who often meet and exceed general exercise recommendations for pregnant women, but there are no exercise guidelines specifically for these women. Important questions for such women are unanswered in current guidelines: Which activities, exercises and sports can they perform, for how long and at what intensity, without risking their own health and the health of the fetus? How soon can they return to highintensity training and competition after childbirth? The IOC and most National Sports Federations encourage women to participate in all Olympic sport disciplines. The IOC promotes high-level performance, and it is also strongly committed to promoting lifelong health among athletes10-not just during their competitive sporting careers. With an increasing number of elite female athletes competing well into their thirties, many may wish to become pregnant, and some also want to continue to compete after childbirth. With this background, the IOC assembled an international expert committee to review the literature on physical activity and exercise (1) during pregnancy and (2) after childbirth, using rigorous systematic review and search criteria.11 For efficiency, where sex is not specified, the reader should assume that this manuscript about pregnancy and childbirth refers to females (ie, \u27the elite athlete who wishes to train at altitude\u27 is used in preference to \u27the elite female athlete...\u27). AIMS The September 2015 IOC meeting of 16 experts in Lausanne had three aims. They were to: 1. Summarise common conditions, illnesses and complaints that may interfere with strenuous exercise and competition, during pregnancy and after childbirth; 2. Provide recommendations for exercise training during pregnancy and after childbirth, for highlevel regular exercisers and elite athletes; and 3. Identify major gaps in the literature that limit the confidence with which recommendations can be made. METHODS For each section of the document, a search strategy was performed using search terms such as \u27pregnancy\u27 OR \u27pregnant\u27 OR \u27postpartum\u27 AND \u27exercise\u27 OR \u27physical activity\u27 OR\u27leisure activity\u27 OR\u27leisure\u27 OR \u27recreation\u27 OR \u27recreational activity\u27 or \u27physical fitness\u27 OR \u27occupational activity\u27 AND terms related to the condition under study (eg, \u27gestational diabetes\u27). Available databases were searched, with an emphasis on PubMed, EMBASE, Cochrane, PEDro, Web of Science and SPORTDiscus. In addition, existing guidelines with reference lists were scanned. The review of each topic followed the general order: prevalence of the condition in the general pregnant or postpartum population, prevalence in high-level exercisers or elite athletes, risk factors in the general population and in relation to exercise and sport, and effect of preventive and treatment interventions. Level of evidence and grade of recommendations are according to the Cochrane handbook (table 1) for prevention and treatment interventions only. Each member of the working group was assigned to be the lead author of one or more topics and 1-3 others were assigned to review each topic. A first full consensus draft was reviewed before and during the 3-day IOC meeting (27-29 September 2015), and a new version of each topic was submitted to the meeting chairs (KB and KMK) shortly after the meeting. Each topic leader made amendments before sending a new version for comments to the working group
Small UAS Detect and Avoid Requirements Necessary for Limited Beyond Visual Line of Sight (BVLOS) Operations
Potential small Unmanned Aircraft Systems (sUAS) beyond visual line of sight (BVLOS) operational scenarios/use cases and Detect And Avoid (DAA) approaches were collected through a number of industry wide data calls. Every 333 Exemption holder was solicited for this same information. Summary information from more than 5,000 exemption holders is documented, and the information received had varied level of detail but has given relevant experiential information to generalize use cases. A plan was developed and testing completed to assess Radio Line Of Sight (RLOS), a potential key limiting factors for safe BVLOS ops. Details of the equipment used, flight test area, test payload, and fixtures for testing at different altitudes is presented and the resulting comparison of a simplified mathematical model, an online modeling tool, and flight data are provided. An Operational Framework that defines the environment, conditions, constraints, and limitations under which the recommended requirements will enable sUAS operations BVLOS is presented. The framework includes strategies that can build upon Federal Aviation Administration (FAA) and industry actions that should result in an increase in BVLOS flights in the near term.
Evaluating approaches to sUAS DAA was accomplished through five subtasks: literature review of pilot and ground observer see and avoid performance, survey of DAA criteria and recommended baseline performance, survey of existing/developing DAA technologies and performance, assessment of risks of selected DAA approaches, and flight testing. Pilot and ground observer see and avoid performance were evaluated through a literature review. Development of DAA criteria—the emphasis here being well clear— was accomplished through working with the Science And Research Panel (SARP) and through simulations of manned and unmanned aircraft interactions. Information regarding sUAS DAA approaches was collected through a literature review, requests for information, and direct interactions. These were analyzed through delineation of system type and definition of metrics and metric values. Risks associated with sUAS DAA systems were assessed by focusing on the Safety Risk Management (SRM) pillar of the SMS (Safety Management System) process. This effort (1) identified hazards related to the operation of sUAS in BVLOS, (2) offered a preliminary risk assessment considering existing controls, and (3) recommended additional controls and mitigations to further reduce risk to the lowest practical level. Finally, flight tests were conducted to collect preliminary data regarding well clear and DAA system hazards
A phase I study of intraperitoneal nanoparticulate paclitaxel (Nanotax®) in patients with peritoneal malignancies
PURPOSE: This multicenter, open-label, dose-escalating, phase I study evaluated the safety, tolerability, pharmacokinetics and preliminary tumor response of a nanoparticulate formulation of paclitaxel (Nanotax®) administered intraperitoneally for multiple treatment cycles in patients with solid tumors predominantly confined to the peritoneal cavity for whom no other curative systemic therapy treatment options were available. METHODS: Twenty-one patients with peritoneal malignancies received Nanotax® in a modified dose-escalation approach utilizing an accelerated titration method. All patients enrolled had previously received chemotherapeutics and undergone surgical procedures, including 33 % with optimal debulking. Six doses (50–275 mg/m2) of Cremophor-free Nanotax® were administered intraperitoneally for one to six cycles (every 28 days). RESULTS: Intraperitoneal (IP) administration of Nanotax® did not lead to increases in toxicity over that typically associated with intravenous (IV) paclitaxel. No patient reported ≥Grade 2 neutropenia and/or ≥Grade 3 neurologic toxicities. Grade 3 thrombocytopenia unlikely related to study medication occurred in one patient. The peritoneal concentration–time profile of paclitaxel rose during the 2 days after dosing to peritoneal fluid concentrations 450–2900 times greater than peak plasma drug concentrations and remained elevated through the entire dose cycle. Best response assessments were made in 16/21 patients: Four patients were assessed as stable or had no response and twelve patients had increasing disease. Five of 21 patients with advanced cancers survived longer than 400 days after initiation of Nanotax® IP treatment. CONCLUSIONS: Compared to IV paclitaxel administration, Cremophor-free IP administration of Nanotax® provides higher and prolonged peritoneal paclitaxel levels with minimal systemic exposure and reduced toxicity
Recommendations for standardizing nomenclature for dietary (poly)phenol catabolites
There is a lack of focus on the protective health effects of phytochemicals in dietary guidelines. Although a number of chemical libraries and databases contain dietary phytochemicals belonging to the plant metabolome, they are not entirely relevant to human health because many constituents are extensively metabolized within the body following ingestion. This is especially apparent for the highly abundant dietary (poly)phenols, for which the situation is compounded by confusion regarding their bioavailability and metabolism, partially because of the variety of nomenclatures and trivial names used to describe compounds arising from microbial catabolism in the gastrointestinal tract. This confusion, which is perpetuated in online chemical/metabolite databases, will hinder future discovery of bioactivities and affect the establishment of future dietary guidelines if steps are not taken to overcome these issues. In order to resolve this situation, a nomenclature system for phenolic catabolites and their human phase II metabolites is proposed in this article and the basis of its format outlined. Previous names used in the literature are cited along with the recommended nomenclature, International Union of Pure and Applied Chemistry terminology, and, where appropriate, Chemical Abstracts Service numbers, InChIKey, and accurate mass

Trapping \u3ci\u3ePhyllophaga \u3c/i\u3espp. (Coleoptera: Scarabaeidae: Melolonthinae) in the United States and Canada using sex attractants.
The sex pheromone of the scarab beetle, Phyllophaga anxia, is a blend of the methyl esters of two amino acids, L-valine and L-isoleucine. A field trapping study was conducted, deploying different blends of the two compounds at 59 locations in the United States and Canada. More than 57,000 males of 61 Phyllophaga species (Coleoptera: Scarabaeidae: Melolonthinae) were captured and identified. Three major findings included: (1) widespread use of the two compounds [of the 147 Phyllophaga (sensu stricto) species found in the United States and Canada, males of nearly 40% were captured]; (2) in most species intraspecific male response to the pheromone blends was stable between years and over geography; and (3) an unusual pheromone polymorphism was described from P. anxia. Populations at some locations were captured with L-valine methyl ester alone, whereas populations at other locations were captured with L-isoleucine methyl ester alone. At additional locations, the L-valine methyl ester-responding populations and the L-isoleucine methyl ester-responding populations were both present, producing a bimodal capture curve. In southeastern Massachusetts and in Rhode Island, in the United States, P. anxia males were captured with blends of L-valine methyl ester and L-isoleucine methyl ester
