Purpose The purpose of this paper is to examine the level of physical preparation for bushfire among Victorian residents in established high risk bushfire locations, and to assess whether these levels of preparation changed over time. Design/methodology/approach Data were analysed from a telephone survey among Victorian residents (n=614-629) living in high risk bushfire locations over a three-year period (2012-2014). The survey measured residents’ bushfire awareness, knowledge, planning, preparation and engagement with bushfire services. This paper focusses on the extent to which respondents undertook physical preparatory bushfire activities over the three-year period using: first, principal components analysis to generate a single preparation variable by identifying a smaller number of uncorrelated variables (or principal components) from a larger set of data, second, analysis of variance to assess differences in preparation scores between years, and third, Tukey’s honest significant difference test to confirm where the differences occurred between groups. Findings Results indicated only moderate levels of physical preparation for bushfires amongst respondents. The activities that respondents rated the lowest were: “having protective covers for windows” and “having firefighting equipment to protect the house”. A significant difference in total preparation scores over time was observed, F(2, 1,715)=6.159, p<0.005, with lower scores in 2012 compared with 2013 and 2014 scores. Social implications This study found some marginal improvements in levels of physical bushfire preparation from 2012 to 2014. However, the results indicate only moderate levels of preparation overall, despite respondents living in established high risk locations. Originality/value This study provides evidence for the current levels of preparedness in high risk bushfire communities, and emphasises the need for future initiatives to focus on specific bushfire preparation activities but also to consider the broader range of interventions that are likely to contribute to desired safety outcomes.

The batik waste industry is one source of water pollution. It must undergo treatment before discharge into the environment. Batik waste treatment technologies can be done biologically, chemically, physically, or combination of three processes. This research applied a combination of biology and physic technologies, namely used spent mushroom of Pleurotus ostreatus as the decolorization agent. Mycelium of P. ostreatus was used as biological agent, and cellulose from spent mushroom was used as physical agent. The aims of this research were to determine the effect of spent mushroom with variation incubation time on batik waste decolorization, and to know the optimum incubation time with highest decolorization batik waste percentage using spent mushroom of P. ostreatus. This research used experimental method with completely randomized design (CRD). The data obtained were statistically analyzed using Varian Test (ANOVA) on confidence level of 95% and 99% and continued with Honest Significant Difference Test (BNJ) with 95% confidence level. The result showed that variation incubation time treatment of batik waste decolorization used spent mushroom of P. ostreatus provide a highly signification effect on batik waste decolorization. The optimum incubation time was 60 hour (LW5), with decolorization percentage was 85,64%.

Purpose The purpose of this paper is to explore how people differently create meaning from photos taken by either a lifelogging camera (LC) (i.e. automatic capture) or a mobile phone camera (MC) (i.e. manual capture). Moreover, the paper investigates the different changes in the interpretative stance of lifelog photos and manually captured photos over time to figure out how the LC application could support the users’ iconological interpretation of their past. Design/methodology/approach A 200-day longitudinal study was conducted with two different user groups that took and reviewed photos taken by either a LC or a MC. The study was structured in two phases: a photo collection phase, which lasted for five days (Day 1‒Day 5), and a three-part semi-structured interview phase, which was conducted on Days 8, 50 and 200. Findings Results revealed that the interpretative stance of the LC group changed greatly compared to the MC group that kept a relatively consistent interpretative stance over time. A significant difference between the two groups was revealed on Day 200 when the lifelog photos provoked a more iconological and less pre-iconographical interpretative stance. This stance allowed the viewers of lifelog photos to systemically interpret the photos and look back upon their past with different viewpoints that were not recognized before. Originality/value This paper contributes to further understand the dynamic change in interpretative stance of lifelog photos compared to manually captured photos through a longitudinal study. The results of this study can support the design guidelines for a LC application that could give opportunities for users to create rich interpretations from lifelog photos.

Abstract Background Levofloxacin prophylaxis (LVXp) is recommended in children with severe neutropenia from underlying malignancy or hematopoietic cell transplantation (HCT). The impact of LVXp on the epidemiology of viridans group streptococcus bloodstream infections (VGS-BSI) is unknown. At our center, LVXp was prescribed to high-risk children with expected prolonged neutropenia (ANC &lt; 100, &gt; 7 days) as part of a clinical trial (2013-17) and routinely since November 2018. We aim to describe our local epidemiology, antibiotic susceptibilities, and clinical outcomes of VGS-BSI over time. Methods VGS-BSI from 1/1/10-1/31/21 were identified via the laboratory database. Clinical data of patients followed at NCH with underlying malignancy, severe neutropenia, or HCT were extracted from the electronic health record. Available VGS isolates were subcultured, species identification confirmed by MALDI-ToF or 16s rDNA sequencing and susceptibility to penicillin (PCN), cefepime (CEF), vancomycin (VAN), and LVX performed via Etest per CLSI M100 guidelines. Non-parametric descriptive statistics were applied. Results Over a 10-yr period, 111 VGS-BSI occurred in 93 patients (Table 1); 15 (16%) patients had ≥ 2 VGS-BSI. 80 (86%) patients had fever and neutropenia (F&N); 26 (28%) required ICU care for vasopressors (N=17, 18%) or mechanical ventilation (N=10, 11%). Most VGS isolates were S. mitis/oralis group. In total, 15 (16%) patients received LVXp ≤ 6 months before VGS-BSI; 9 (10%) had breakthrough VGS-BSI while receiving LVXp and all isolates were LVX resistant. Figure 1 shows susceptibilities: overall, 24% of isolates had frank resistance to PCN, 19% CEF, 13% LVX; all were VAN susceptible. When evaluating for changes in susceptibilities over time, there was a significant difference in the proportion of LVX-resistant isolates (p=0.009, Cochran-Armitage χ 2), but not CEF (p=0.08) or PCN (p=0.86). Table 1. Demographic and Clinical Characteristics of Immunocompromised Children with Viridans Group Streptococci Bloodstream Infections (VGS-BSI) Figure 1. Antimicrobial Susceptibility Profile of Viridans Group Streptococci Bloodstream Isolates from Immunocompromised children, 2010-2021. Of 111 VGS-BSI reported during the study period from immunocompromised children, 83 (75%) were available for further testing. Antimicrobial susceptibility testing was performed by Etest and interpreted per CLSI M100. Susceptibility profiles to penicillin (PCN), cefepime (CEP) and, levofloxacin (LVX) are shown. Abbreviations: S—susceptible, I—intermediate, R—resistant. Conclusion Breakthrough, LVX-resistant VGS-BSI occurred in 10% of patients, most frequently in children with AML or HCT. Over time, there was a trend towards increased LVX resistance in the cohort. Routine antimicrobial testing and ongoing monitoring for emergence of resistance are warranted to inform local prophylaxis and empirical antibiotic strategies for high-risk children with F&N.

Turbo chrysostumus is commonly known by fishermen community as moon-eyed snail and has common names of yellow-mouth turban or gold-mouth turban. These biota live in rocky beach and coral reefs surface filled with alga. They are also easily collected and used for high nutritive food for coastal villagers. The study of survival and growth of turbo youngsters in relation with different temperature is very limited. This study was done in January 5 – May 4, 2015 in the laboratory with the objective of observing the effect of optimum temperature range on their survival and growth. Based on ANOVA statistical analyses, the temperature had significsant effect on the survival of the turbo youngsters (p<0.05). “Honest Significant Difference” test revealed that control temperature (P1), 26±0.5°C (P2), and 28±0.5°C (P3) produced a significantly different effect on the survival compared with that in 30±0.5°C (P4). Higher growth rate was recorded in  26±0.5°C balanced with high food consumability. The relationship analysis of height shell-weight of wet body in all treatments indicated similar pattern of minor allometric (b<3).

Purpose Strategic typologies are applied to investigate strategy–performance relationship. The typology of Miles and Snow (1978) is one of them, but the methodology applied for identification of strategic types for archival financial data is questionable on three grounds: no standard procedure for categorization of strategic types; identification of reactor strategy is always ignored; and the behavior of firms’ strategic orientation over time is under-researched. Besides, the assumptions that viable strategies are expected to perform equally well, outperform reactors and distributed evenly are not overwhelmingly supported. The purpose of this paper is to address these issues. Design/methodology/approach A refined scoring methodology is developed and used for identification of all strategic types, including reactors, by investigating the consistency of the firms over time. Empirical analysis using seven years of data of 121 joint stock firms of the textile sector in Pakistan is performed to test the assumptions regarding presence, distribution and performance of strategic types. Findings There is significant difference in the distribution of the strategic types. Pure defenders and pure prospectors are non-existing, whereas a reasonable number of reactors are present. Overall difference in performance among strategies is generally insignificant and viable strategies outperformed reactors. The effect of size on performance is also insignificant. However, there is variation in performance of strategies with variation in size. Strategy is the better predictor of performance than size. Originality/value The transition of strategic stance of the firms over time and the identification of reactor strategy from archived financial data are the important outcomes of the proposed methodology. The proposed methodology can be used for any longitudinal study for identification of all possible strategic types and can also be used for any other typological research.

This study aims to determine the growth response of the vegetative stadia of three soybean varieties which are widely used in East Java on acid soils that have been given biological fertilizers from various Trichoderma isolates. The experiment was arranged factorially using a completely randomized design. The first factor was the variety consisting of Detam 3, Detam 4, Gema, Dering 1, and Burangrang. The second factor was Trichoderma isolates formulated as bio fertilizers, consisting of Tc-Jjr-02, Tc-Pjn-01, and Tc-Jro-01. Overall this experiment has 60 experimental units. Data were analyzed by variance analysis (ANOVA) followed by an honest significant difference test at the level of 5%. The results showed that there was no interaction between soybean varieties and Trichoderma isolates formulated in bio fertilizer. Soybean varieties significantly affected plant height, wet weight, and dry weight of roots and stover at 21 days after planting. The Burangrang variety shows the best growing ability in acid soils. There was no interaction between soybean varieties and Trichoderma bio fertilizers. Trichoderma isolate Tc-Jjr-02 increased the wet weight and dry weight of the roots and roots by 48.2 and 54.5%, respectively, and 38.9 and 48.2% compared to without Trichoderma. Trichoderma application maintains soil acidity between pH 4.50-4.67.

Currently, no objective method exists for estimating the rate of change in the colour of meat. Consequently, the purpose of this work is to develop a procedure capable of monitoring the change in colour of meat over time, environment and ingredients. This provides a useful tool to determine which storage environments and ingredients a manufacturer should add to meat to reduce the rate of change in colour. The procedure consists of taking multi-spectral images of a piece of meat as a function of time, clustering the pixels of these images into categories, including several types of meat, and extracting colour information from each category. The focus has primarily been on achieving an accurate categorisation since this is crucial to develop a useful method. The categorisation is done by applying an orthogonal transformation followed by k-means clustering. The purpose of the orthogonal transformation is to reduce the noise and amount of data while enhancing the difference between the categories. The orthogonal transformations principal components analysis, minimum noise fraction analysis and kernel-based versions of these have been applied to test which produce the most accurate categorisation.

The tropical climate in Indonesia supports the presence of many types of plants that have the potential to produce abundant vegetables and fruit, however the presence of fruit flies is an obstacle to fruit and vegetable productivity. Lemongrass and basil have been studied to contain several compounds that have the potential to control fruit fly attacks. This study aims to determine the effect of the ethanol extract of lemongrass pseudo stem (Cymbopogon citrates) and basil (Ocimum sanctum) leaves on the catch of Bactrocera fruit flies and to determine the concentration of the extract that has the highest number of catches. The method used in sampling was factorial randomized block design (RBD). The ethanol extract of the pseudo-lemongrass, the extract of basil leaves or the mixture of both extract (1:1) that was given at concentrations of 15%, 30% and 45% was dropped onto a piece of cotton and for then be put within a trap before placing on the tree. The cathes obtained from each extract at each concentration were observed if they show a significant difference in the number of fruit fly. Data were tested using analysis of variance (F test) at α = 0.05, followed by the Honest Significant Difference test (HSD). The results showed that the catch obtained from ethanol extract of lemongrass pseudo stem or from basil leaf ectract as well as  from their mixture had a significantly higher number of Bactrocera fruit flies than without using these extracts. The difference in extract concentration did not cause a difference in the ability to attract fruit flies. The conclusion of this study is that there is an effect of the  pseudo stem ethanol extract of lemongrass or basil leaf ectract as well as their mixture on the catch of Bactrocera fruit flies and these extract are recommended as non-synthetic pesticidesalternatives.

AbstractQuarrying and abrasion are the two principal processes responsible for glacial erosion of bedrock. The morphologies of glacier hard beds depend on the relative effectiveness of these two processes, as abrasion tends to smooth bedrock surfaces and quarrying tends to roughen them. Here we analyze concentrations of bedrock discontinuities in the Tsanfleuron forefield, Switzerland, to help determine the geologic conditions that favor glacial quarrying over abrasion. Aerial discontinuity concentrations are measured from scaled drone-based photos where fractures and bedding planes in the bedrock are manually mapped. A Tukey honest significant difference test indicates that aerial concentration of bed-normal bedrock discontinuities is not significantly different between quarried and non-quarried areas of the forefield. Thus, an alternative explanation is needed to account for the spatial variability of quarried areas. To investigate the role that bed-parallel discontinuities might play in quarrying, we use a finite element model to simulate bed-normal fracture propagation within a stepped bed with different step heights. Results indicate that higher steps (larger spacing of bed-parallel discontinuities) propagate bed-normal fractures more readily than smaller steps. Thus, the spacing of bed-parallel discontinuities could exert strong control on quarrying by determining the rate that blocks can be loosened from the host rock.
