Commercial production of tomatoes in Western Australia

The tomato crop is subject to many hazards. Pests, diseases and adverse environmental conditions are frequently encountered and must be overcome. This bulletin has been prepared to give growers, whether they be experienced or new to tomato culture, an outline of the more important cultural practices involved in producing satisfactory crops. Common diseases and pests are described and where possible recommendations for their control are given.https://researchlibrary.agric.wa.gov.au/bulletins3/1004/thumbnail.jp

What do Australian medical programs teach medical students about breastfeeding?

Objectives To investigate what breastfeeding information is included in Australian medical program curricula and how and by whom it is taught. Method The ten Australian medical schools who have graduated students from their current programs were asked to nominate a person to complete an 11-item questionnaire. Data collected from the questionnaire included: if and where breastfeeding is located within the medical program; who teaches medical students about breastfeeding; and other opportunities medical students have to learn about breastfeeding. Results The questionnaire was completed and returned by nine of the ten nominated people, giving a response rate of 90 percent. One respondent did not know whether breastfeeding was included in the curriculum. The advantages of breastfeeding, normal breastfeeding management and breastfeeding problems were taught within the curriculum in the remaining eight programs. All medical programs encouraged contact with breastfeeding mothers and infants although it was not clear whether this included clinical teaching. Teaching about breastfeeding was undertaken by people from a number of different professional areas (e.g. midwives, doctors, lactation consultants) with all schools utilizing a minimum of three professions. Conclusions While most Australian medical students received some instruction about breastfeeding, the subject areas taught and the method of teaching varied widely between medical programs. Some students received little formal teaching, with patient contact being the main avenue for gaining breastfeeding knowledge and experience. Others had minimal clinical contact. Ideally breastfeeding should be incorporated into the broader curriculum whenever it is applicable and include both formal teaching and clinical instruction

Development of Athletes Conceptions of Sport Officials Authority

This study examined baseball players\u27 conceptions of umpires\u27 authority. Eighty male players, ages 6-22 years, completed an abbreviated Inventory of Piaget\u27s Developmental Tasks (Furth, 1970), which was used to measure cognitive development. They then heard recorded scenarios describing conflicts with an umpire and a parent. Players indicated if they would argue with the authorities, why they obey the authorities (obedience), and why the authorities get to make decisions (legitimacy). Obedience and legitimacy responses were categorized into Damon\u27s (1977) three levels. Measures of arguing, obedience, and legitimacy were analyzed for four age levels and three levels of cognitive development. Older and more cognitively developed players were more likely to argue with authorities. Conceptions of obedience and legitimacy were positively associated with age, though they were not related to scores of cognitive development. The positive relationship between age and authority conceptions and the absence of a relationship between cognitive development and authority conceptions are both consistent with Damon\u27s position

Stakeholder participation and corporate social responsibility : a critical study of problem gambling in the New South Wales registered club sector

Within the context of "business-in-society", this study highlights a dialectical dilemma for registered clubs in New South Wales, between the economic and the social perspectives of their gambling operations. The research sought to discover the circumstances in which stakeholder interaction around the various perspectives on problem gambling might lead to a socially responsible approach to the management of poker machine gambling in clubs. The study's methodology adapted a learning history framework of participative action research, and recruited stakeholders to act as "co-researchers" in a transparent-research approach to the exploration of the research question. Taking a critical orientation, the study uncovered significant tensions between stakeholders, and drew attention to State Government policy and administration of gambling. The findings highlighted the need for a public health approach to gambling administration in the State. The position of the government department in the stakeholder network was found to leave it vulnerable to the introduction of an interloper which could have the potential, by engaging strategically with other stakeholders, to assume an influential role in the network dynamic. Drawing on the co-researchers' perspectives on problem gambling, an interloper's access to the public health approach to gambling policy and administration was taken to offer a possible impetus for such a move, and the State and Federal health departments were suggested to represent potential interlopers. The social responsibility of clubs was found to be influenced by the government's policy approach to problem gambling. The discussion situates this finding in a wider context of the policy influences on the contemporary practice of corporate responsibility in Australia. The capacity for change in the social responsibility for problem gambling was considered in a sector-wide context, and the intervention of a potential interloper was found to offer the possibility of a catalyst for change. The methodological contribution of the study is its proposal for a critically-inspired framework for multi-stakeholder involvement in exploring the social dimensions of business. This methodology is claimed to have potential for uncovering alternative stakeholder engagements that can contribute to an unsettling of the hegemonic arrangements of a stakeholder network

51 Eri and GJ 3305: A 10-15 Myr old binary star system at 30 parsecs

Following the suggestion of Zuckerman et al. (2001, ApJ, 562, L87), we consider the evidence that 51 Eri (spectral type F0) and GJ 3305 (M0), historically classified as unrelated main sequence stars in the solar neighborhood, are instead a wide physical binary system and members of the young beta Pic moving group (BPMG). The BPMG is the nearest (d < 50 pc) of several groups of young stars with ages around 10 Myr that are kinematically convergent with the Oph-Sco-Cen Association (OSCA), the nearest OB star association. Combining SAAO optical photometry, Hobby-Eberly Telescope high-resolution spectroscopy, Chandra X-ray data, and UCAC2 catalog kinematics, we confirm with high confidence that the system is indeed extremely young. GJ 3305 itself exhibits very strong magnetic activity but has rapidly depleted most of its lithium. The 51 Eri/GJ 3305 system is the westernmost known member of the OSCA, lying 110 pc from the main subgroups. The system is similar to the BPMG wide binary HD 172555/CD -64d1208 and the HD 104237 quintet, suggesting that dynamically fragile multiple systems can survive the turbulent environments of their natal giant molecular cloud complexes, while still being imparted high dispersion velocities. Nearby young systems such as these are excellent targets for evolved circumstellar disk and planetary studies, having stellar ages comparable to that of the late phases of planet formation.Comment: 27 pages, 7 figures.

Mineral Acquisition from Clay by Budongo Forest Chimpanzees

Chimpanzees of the Sonso community, Budongo Forest, Uganda were observed eating clay and drinking clay-water from waterholes. We show that clay, clay-rich water, and clay obtained with leaf sponges, provide a range of minerals in different concentrations. The presence of aluminium in the clay consumed indicates that it takes the form of kaolinite. We discuss the contribution of clay geophagy to the mineral intake of the Sonso chimpanzees and show that clay eaten using leaf sponges is particularly rich in minerals. We show that termite mound soil, also regularly consumed, is rich in minerals. We discuss the frequency of clay and termite soil geophagy in the context of the disappearance from Budongo Forest of a formerly rich source of minerals, the decaying pith of Raphia farinifera palms

An Examination of Faculty and Staff Collaboration and Relationships In Higher Education

Collaboration between academic and student affairs professionals is an important means of increasing student success; however, historical divides between these units have made implementation of these efforts challenging. This quantitative study sought to evaluate the perceptions of faculty and student affairs staff towards collaborative efforts and toward one another within a single campus of a comprehensive regional university within the southeast. Findings show that while both faculty and staff value collaborations and believe they positively impact student success, these units do not experience equitable voice and responsibility within collaborative efforts when conducted. Additionally, differences were found in enjoyment of collaborative efforts and how various traits impacted willingness to collaborate. Significant differences were also found in the perceptions faculty and staff hold toward one another, both in perceptions of the roles and within relational descriptors. Finally, this study identified that interpersonal relationships and perceptions do in fact relate to willingness to collaborate, but do so in differing ways for the two employee classifications. Implications for institutional leadership and recommendations for future research are provided

Effects of Heating and Cooling on Nerve Terminal Impulses Recorded from Cold-sensitive Receptors in the Guinea-pig Cornea

An in vitro preparation of the guinea-pig cornea was used to study the effects of changing temperature on nerve terminal impulses recorded extracellularly from cold-sensitive receptors. At a stable holding temperature (31–32.5°C), cold receptors had an ongoing periodic discharge of nerve terminal impulses. This activity decreased or ceased with heating and increased with cooling. Reducing the rate of temperature change reduced the respective effects of heating and cooling on nerve terminal impulse frequency. In addition to changes in the frequency of activity, nerve terminal impulse shape also changed with heating and cooling. At the same ambient temperature, nerve terminal impulses were larger in amplitude and faster in time course during heating than those recorded during cooling. The magnitude of these effects of heating and cooling on nerve terminal impulse shape was reduced if the rate of temperature change was slowed. At 29, 31.5, and 35°C, a train of 50 electrical stimuli delivered to the ciliary nerves at 10–40 Hz produced a progressive increase in the amplitude of successive nerve terminal impulses evoked during the train. Therefore, it is unlikely that the reduction in nerve terminal impulse amplitude observed during cooling is due to the activity-dependent changes in the nerve terminal produced by the concomitant increase in impulse frequency. Instead, the differences in nerve terminal impulse shape observed at the same ambient temperature during heating and cooling may reflect changes in the membrane potential of the nerve terminal associated with thermal transduction
