Sweet talking to ethnic customers : a field experiment on the links between entrepreneurial business planning, cultural sensitivity and sales growth

The purpose of this study was to test whether calculated inclusion of cultural sensitivity in a selected entrepreneurial business planning (EBP) process could increase sales growth in a test market and to explore the implications of a positive answer for the theory and practice of entrepreneurial business planning. Execution of a pretest-posttest control group experimental design measured and compared the implemented effectiveness of a planned entrepreneurial initiative based on cultural sensitivity. Though small in scale and limited in focus, the initiative qualified as an example of entrepreneurial business planning (EBP) and could be used to apply, test and extend aspects of the developing theory in this field of entrepreneurship research. Since the initiative was planned to overcome a culturally-defined impediment to business growth, it also offered opportunity to explore the specific importance of cultural variables in the context of EBP.

A planned sales-promotion was offered to a control group (receiving information in English) and a treatment group (who received the information in the language of ethnic origin). The sixty subjects had been chosen at random from a population of route-trade retailers of defined ethnic origins (Greek, Lebanese and Chinese) and randomly assigned to control and treatment groups. Monthly sales averages of the promoted product were measured before and after treatment. A Chi Square test was used to evaluate the relative proportion of the control and treatment groups who accepted the promotional offer. A two sample t-test procedure and complementary non-parametric Mann-Whitney test were performed to compare the mean sales-performance change of the two groups. Analysis showed that there was a significant increase in mean sales when the planned entrepreneurial initiative was communicated in the relevant language of origin.

The experimental results have specific practical relevance to revitalising the deteriorating route-trade segment of the Australian confectionery market through increasing the sales growth of wholesalers who are prepared to act entrepreneurially and include cultural sensitivity as an element in planning and implementation. By introducing cultural sensitivity as a necessary extension of a plan’s communications role, the results also have general theoretical implications for the developing paradigm of entrepreneurial business planning.

The strategic mindset of Australian manufacturing managers : some missing links

Manufacturing managers have a measurable mindset (or frame) that structures their response to the manufacturing environment. Most importantly, this frame represents a set of assumptions about the relative prominence of concepts in the manufacturing domains, about the nature of people, and about the sensemaking processes required to understand the nature of the manufacturing environment as seen through the eyes of manufacturing managers. This paper uses work in the area of text analysis and extends the scope of a methodology that has been approached from two different directions by Carley ( Journal of Organizational Behavior , 18 (51), 533-558, 1997) and Gephart ( Journal of Organizational Behavior , 18 (51), 583-622, 1997). This methodology is termed collocate analysis. Based on the analysis of transcripts of interviews of Australian manufacturing managers mind maps of the concepts used by these managers have been constructed. From an analysis of these mind maps it is argued that strategy plays a minor role in their thinking second only to the improvement domain, whereas design and related concepts play a dominant role in their day-to-day thinking

Cordycepin-hypersensitive growth links elevated polyphosphate levels to inhibition of poly(A) polymerase in Saccharomyces cerevisiae

To identify genes involved in poly(A) metabolism, we screened the yeast gene deletion collection for growth defects in the presence of cordycepin (3′-deoxyadenosine), a precursor to the RNA chain terminating ATP analog cordycepin triphosphate. Δpho80 and Δpho85 strains, which have a constitutively active phosphate-response pathway, were identified as cordycepin hypersensitive. We show that inorganic polyphosphate (poly P) accumulated in these strains and that poly P is a potent inhibitor of poly(A) polymerase activity in vitro. Binding analyses of poly P and yeast Pap1p revealed an interaction with a k_D in the low nanomolar range. Poly P also bound mammalian poly(A) polymerase, however, with a 10-fold higher k_D compared to yeast Pap1p. Genetic tests with double mutants of Δpho80 and other genes involved in phosphate homeostasis and poly P accumulation suggest that poly P contributed to cordycepin hypersensitivity. Synergistic inhibition of mRNA synthesis through poly P-mediated inhibition of Pap1p and through cordycepin-mediated RNA chain termination may thus account for hypersensitive growth of Δpho80 and Δpho85 strains in the presence of the chain terminator. Consistent with this, a mutation in the 3′-end formation component rna14 was synthetic lethal in combination with Δpho80. Based on these observations, we suggest that binding of poly P to poly(A) polymerase negatively regulates its activity.

Yhh1p/Cft1p directly links poly(A) site recognition and RNA polymerase II transcription termination

RNA polymerase II (pol II) transcription termination requires co-transcriptional recognition of a functional polyadenylation signal, but the molecular mechanisms that transduce this signal to pol II remain unclear. We show that Yhh1p/Cft1p, the yeast homologue of the mammalian AAUAAA interacting protein CPSF 160, is an RNA-binding protein and provide evidence that it participates in poly(A) site recognition. Interestingly, RNA binding is mediated by a central domain composed of predicted -propeller-forming repeats, which occurs in proteins of diverse cellular functions. We also found that Yhh1p/Cft1p bound specifically to the phosphorylated C-terminal domain (CTD) of pol II in vitro and in a two-hybrid test in vivo. Furthermore, transcriptional run-on analysis demonstrated that yhh1 mutants were defective in transcription termination, suggesting that Yhh1p/Cft1p functions in the coupling of transcription and 3'-end formation. We propose that direct interactions of Yhh1p/Cft1p with both the RNA transcript and the CTD are required to communicate poly(A) site recognition to elongating pol II to initiate transcription termination.

Links between pollen, atopy and the asthma epidemic

Pollen allergy has been found in 80–90% of childhood asthmatics and 40–50% of adult-onset asthmatics. Despite the high prevalence of atopy in asthmatics, a causal relationship between the allergic response and asthma has not been clearly established. Pollen grains are too large to penetrate the small airways where asthma occurs. Yet pollen cytoplasmic fragments are respirable and are likely correlated with the asthmatic response in allergic asthmatics. In this review, we outline the mechanism of pollen fragmentation and possible pathophysiology of pollen fragment-induced asthma. Pollen grains rupture within the male flowers and emit cytoplasmic debris when winds or other disturbances disperse the pollen. Peak levels of grass and birch pollen allergens in the atmosphere correlated with the occurrence of moist weather conditions during the flowering period. Thunderstorm asthma epidemics may be triggered by grass pollen rupture in the atmosphere and the entrainment of respirable-sized particles in the outflows of air masses at ground level. Pollen contains nicotinamide adenine dinucleotide phosphate (reduced) oxidases and bioactive lipid mediators which likely contribute to the inflammatory response. Several studies have examined synergistic effects and enhanced immune response from interaction in the atmosphere, or from co-deposition in the airways, of pollen allergens, endogenous pro-inflammatory agents, and the particulate and gaseous fraction of combustion products. Pollen and fungal fragments also contain compounds that can suppress reactive oxidants and quench free radicals. It is important to know more about how these substances interact to potentially enhance, or even ameliorate, allergic asthma.

Oral language competence in incarcerated young offenders : links with offending severity

Previous research in Australia and overseas has shown that young offenders serving community-based orders are at high-risk for undetected but clinically significant oral language difficulties. However, this phenomenon has received little attention in incarcerated samples, and links with offending severity, mental health, and other markers of early risk have not previously been systemically examined. A cross-sectional examination of 100 young offenders (mean age 19.03 years) completing custodial sentences in Victoria, Australia was conducted. A range of standardized oral language, IQ, mental health, and offending severity measures was employed. Forty-six per cent of participants were classified as language impaired (LI), and these were compared with the non-LI sub-group on background and offending variables. When the sub-group with high scores on a measure of offending severity was compared with those with (relatively) lower offending scores, significant differences on a range of language measures were identified. A range of early risk indicators (such as placement in Out of Home Care) was also examined with respect to language impairment in this high-risk group. Results are discussed with respect to policy and practice pertaining to early intervention for vulnerable children, and implications for service delivery within the justice system. In particular, emphasis is placed on the need to closely examine the oral language skills of children who struggle with the transition to literacy and then display behavioural difficulties in the classroom. Once a young person is engaged with youth justice services, a high index of suspicion should be maintained with respect to their oral language skills; for example, in relation to forensic interviewing and the ability to benefit from verbally mediated interventions.
