Assessing Espoused Goals in Private Family Firms Using Content Analysis

Understanding how private family firms gauge performance is of great interest to family business scholars. Unfortunately, finding comparable data to understand differences in the performance of such firms is challenging. This study draws from the organizational identity literature to show how private family firms communicate different goals in publicly available organizational narratives. The authors illustrate a process using content analysis that allows family business scholars to create a comparative data set that captures both normative and utilitarian goals using website and press release narratives from a sample of Australian firms.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Phosphate concentration and arbuscular mycorrhizal colonisation influence the growth, yield and expression of twelve PHT1 family phosphate transporters in foxtail millet (Setaria italica)

Phosphorus (P) is an essential element which plays several key roles in all living organisms. Setaria italica (foxtail millet) is a model species for panacoid grasses including several millet species widely grown in arid regions of Asia and Africa, and for the bioenergy crop switchgrass. The growth responses of S. italica to different levels of inorganic phosphate (Pi) and to colonisation with the arbuscular mycorrhizal fungus Funneliformis mosseae (syn. Glomus mosseae) were studied. Phosphate is taken up from the environment by the PHT1 family of plant phosphate transporters, which have been well characterized in several plant species. Bioinformatic analysis identified 12 members of the PHT1 gene family (SiPHT1;1-1;12) in S. italica, and RT and qPCR analysis showed that most of these transporters displayed specific expression patterns with respect to tissue, phosphate status and arbuscular mycorrhizal colonisation. SiPHT1;2 was found to be expressed in all tissues and in all growth conditions tested. In contrast, expression of SiPHT1;4 was induced in roots after 15 days growth in hydroponic medium of low Pi concentration. Expression of SiPHT1;8 and SiPHT1;9 in roots was selectively induced by colonisation with F. mosseae. SiPHT1;3 and SiPHT1;4 were found to be predominantly expressed in leaf and root tissues respectively. Several other transporters were expressed in shoots and leaves during growth in low Pi concentrations. This study will form the basis for the further characterization of these transporters, with the long term goal of improving the phosphate use efficiency of foxtail millet

Family-owned businesses: Perspectives on Australian policy

In 2008, a report was commissioned by the European Commission (EC) outlining various policy matters in the field of family business within the auspices of the European Union (EU). Family-owned businesses make a significant contribution to Australia's economic and social welfare. The EC report offers a template for examining family business issues relevant to Australia in seven key areas: political awareness, intergenerational business transfer, financial obligations, balancing business and family, lack of specific education, access to finance for growth and maintaining a skilled workforce. We find that Australian family business policy does not differ markedly to that of Europe. Several policy recommendations are outlined to enhance the recognition of, and provide support to, Australian family-owned businesses.Linda Glassop, Chris Grave

Priorities for Australian family businesses

This paper reports on a national survey which identified priorities that are considered important to the success of Australian family businesses. The FBA and KPMG Family Business Needs Survey 2005 targeted organisations of all sizes and industries across all states. Findings from the survey are extensive and provide noteworthy progress in understanding the issues deemed most important to family businesses, such as balancing family concerns and business interests, balancing short-term and long-term business decisions and increasing profits. As a result of this project, it has: provided an instrument that will allow research investigation on an annual basis; provided initial data sets that highlight key issues facing family business survival; and provided a substantial data set that can be utilised by a range of researchers and practitioners

Phosphate transport in plants

Transport of inorganic phosphate (Pi) through plant membranes is mediated by a number of families of transporter proteins. Studies on the topology, function, regulation and sites of expression of the genes that encode the members of these transporter families are enabling roles to be ascribed to each of them. The Pht1 family, of which there are nine members in the Arabidopsis genome, includes proteins involved in the uptake of Pi from the soil solution and the redistribution of Pi within the plant. Members of this family are H2PO4 –/H+ symporters. Most of the genes of the Pht1 family that are expressed in roots are up-regulated in P-stressed plants. Two members of the Pht1 family have been isolated from the cluster roots of white lupin. These same genes are expressed in non-cluster roots. The evidence available to date suggests that there are no major differences between the types of transport systems that cluster roots and non-cluster roots use to acquire Pi. Differences in uptake rates between cluster and non-cluster roots can be ascribed to more high-affinity Pi transporters in the plasma membranes of cluster roots, rather than any difference in the characteristics of the transporters. The efficient acquisition of Pi by cluster roots arises primarily from their capacity to increase the availability of soil Pi immediately adjacent to the rootlets by excretion of carboxylates, protons and phosphatases within the cluster. This paper reviews Pi transport processes, concentrating on those mediated by the Pht1 family of transporters, and attempts to relate those processes involved in Pi acquisition to likely Pi transport processes in cluster roots

Identification and functional characterization of sugarcane invertase inhibitor (ShINH1): a potential candidate for reducing pre- and post-harvest loss of sucrose in sugarcane

In sugarcane, invertase enzymes play a key role in sucrose accumulation and are also involved in futile reactions where sucrose is continuously degraded during the pre- and post-harvest period, thereby reducing sugar yield and recovery. Invertase inhibitor (INVINH) proteins play a key role in post-translation regulation of plant invertases through which sucrose hydrolysis is controlled. INVINH proteins are small (18 kDa) members of the pectin methylesterase inhibitor superfamily and they are moderately conserved across plants. In the present study, we identified two INVINH genes from sugarcane, ShINH1 and ShINH2. In silico characterization of the encoded proteins revealed 43% sequence identity at the amino acid level, confirming the non-allelic nature of the proteins. The presence of putative signal peptide and subcellular targeting sequences revealed that ShINH1 and ShINH2 likely have apoplasmic and vacuolar localization, respectively. Experimental visualization of ShINH1-GFP revealed that ShINHI is indeed exported to the apoplast. Differential tissue-specific and developmental expression of ShINH1 between leaf, stalk, flower and root suggest that it plays a role in controlling source-sink metabolic regulation during sucrose accumulation in sugarcane. ShINH1 is expressed at relatively high levels in leaves and stalk compared to flowers and roots, and expression decreases significantly toward internodal maturity during stalk development. ShINH1 is expressed at variable levels in flowers with no specific association to floral maturity. Production of recombinant ShINH1 enabled experimental validation of protein function under in vitro conditions. Recombinant ShINH1 potently inhibited acid invertase (IC50 22.5 nM), making it a candidate for controlling pre- and post-harvest deterioration of sucrose in sugarcane. Our results indicate that ShINH1 and ShINH2 are likely to play a regulatory role in sucrose accumulation and contribute to the improvement of sugar yield and recovery in sugarcane
