ECONOMIC ANALYSIS of AMAZON RIVER PRAWN FARMING TO THE MARKETS FOR LIVE BAIT and JUVENILES IN PANTANAL, BRAZIL

The implementation of a hypothetical aquaculture facility with hatchery, nursery and grow-out earthen ponds for raising the Amazon River Prawn Macrobrachium amazonicum in the Pantanal was considered. Eight larviculture cycles per year were projected: four to produce post-larvae for stocking in grow-out bait ponds, and four to stock nursery tanks to sell juveniles as seed to grow-out farms, which produce prawns for human consumption. Annual production would be 146,880 dozen bait prawns and 2,938 thousand juveniles. The assumed sale prices were US$ 1.38 per dozen baits and US$ 15.39 per thousand juveniles. The net present value was US$ 555,890.79, internal rate of return was 48% per year, payback period was 2.4 years and benefit-cost ratio was 3.90. The breakeven price to cover total costs per dozen baits was US$ 0.70 and per thousand juveniles was US$ 17.00, indicating that the selling price assumed for juveniles in base scenario is not realistic. Net return was US$ 84,773.80. The results indicate that this activity would be a lucrative and attractive investment in the Pantanal.

Contributo para a caracterização morfométrica da raça de abelhas melíferas (Apis mellifera iberiensis) da região norte de Portugal

A necessidade de aprofundar o conhecimento sobre a morfologia da abelha melífera portuguesa (Apis mellifera iberiensis) originou o presente estudo. A amostragem definiu-se com base no banco de amostras existentes no Laboratório de Patologia Apícola da ESA-IPB, relativas ao ano de 2015. Cada amostra foi constituída por cinco obreiras adultas conservadas pelo frio (-18 °C). Foram analisadas 124 amostras distribuídas por 16 concelhos (aproximadamente oito por concelho) pertencentes aos distritos de Bragança e Vila Real. As medições efetuadas em cada uma das obreiras foram: peso (PA), comprimento (CA) e largura (LA) do corpo; comprimento (CAA) e largura (LAA) da asa anterior; comprimento (CAP) e largura da asa posterior (LAP); comprimento do fêmur (CF), da tíbia (CT), do basitarso (CBT), do tarso (CTA) e da probóscide (CP) e a largura do basitarso (LBT). Para avaliação destas medidas utilizou-se uma balança analítica de precisão (0,01g) e um paquímetro eletrónico digital (0-100mm±0,02mm). As diferentes variáveis estudadas compararam-se por análise de variância (ANOVA), sendo o teste de Tukey-Kramer HSD utilizado para a comparação múltipla de médias. O peso médio das obreiras do concelho de Vila Pouca de Aguiar (0,123±0,018 g) foi mais elevado (p<0,05) do que o das obreiras dos concelhos de Torre de Moncorvo e Ribeira de Pena (0,106±0,023 g em ambos os casos). Também, as obreiras do concelho de Vila Pouca de Aguiar apresentaram um comprimento médio do corpo (13,065±0,890 mm) superior (p<0,05) às obreiras do concelho de Boticas (12,228±0,958 mm) e uma largura média (4,565 ± 0,392 mm) superior às obreiras de Vila Flor (4,089 ±0,288 mm). Porém, o CAP (6,333±0,303 mm) e o CT (3,179±0,183mm) das obreiras de Vila Pouca de Aguiar foi mais baixo (p<0,05) ao observado nos concelhos de Torre de Moncorvo (6,616±0,361 mm) e Vila Flor (3,358±0,146 mm). As variáveis LAA, LAP, CF, CBT e CP não apresentaram diferenças significativas (p>0,05) entre os concelhos estudados.

Password Based Server Aided Key Exchange

We propose a new password-based 3-party protocol with a formal security proof in the standard model. Under reasonable assumptions we show that our new protocol is more efficient than the recent protocol of Abdalla and Pointcheval (FC 2005), proven in the random oracle model. We also observe some limitations in the model due to Abdalla, Fouque and Pointcheval (PKC 2005) for proving security of such protocols.

Statutory protections from forfeiture of a leasehold estate following Apriaden Pty Ltd v Seacrest Pty Ltd

In Apriaden Pty Ltd v Seacrest Pty Ltd the Victorian Court of Appeal decided that termination of a lease under common law contractual principles following repudiation is an alternative to reliance upon an express forfeiture provision in the lease and that it is outside the sphere of statutory protections given against the enforcing of a forfeiture. The balance of authority supports the first aspect of the decision. This article focuses on the second aspect of it, which is a significant development in the law of leases. The article considers the implications of this decision for essential terms of clauses in leases, argues that common law termination for breach of essential terms should be subject to compliance with these statutory requirements and, as an alternative, suggests a way forward through appropriate law reform, considering whether the recent Victorian reform goes far enough.

Embedding university perspectives in university teaching and learning : lessons learnt and possibilities for reforming/decolonising curriculum

Embedding Indigenous knowledge in the curriculum continues to challenge traditional western perspectives on Indigenous epistemologies and cultures. This paper will initially discuss experiences of embedding Indigenous perspectives in the curriculum at an Australian university. The project was inspired by the Reconciliation Statement which ensured funding through Teaching and Learning Large Grants. Its successful outcomes included the creation of identified positions for Indigenous academics within faculties, creation of a resource hub of relevant teaching materials and consistent documentation and awareness of Indigenous perspectives through interviews and workshops. The paper concludes by critically interrogating the methodology used to conceptualise Indigenous knowledge in embedding Indigenous perspectives in a university curriculum. This paper argues for a thorough curriculum reform if a degree of decolonisation of the western constructed Indigenous knowledge and its living systems are desired.

Contemporary New Zealand coefficients for the Trauma Injury Severity Score: TRISS(NZ)

Aims – To develop local contemporary coefficients for the Trauma Injury Severity Score in New Zealand, TRISS(NZ), and to evaluate their performance at predicting survival against the original TRISS coefficients. Methods – Retrospective cohort study of adults who sustained a serious traumatic injury, and who survived until presentation at Auckland City, Middlemore, Waikato, or North Shore Hospitals between 2002 and 2006. Coefficients were estimated using ordinary and multilevel mixed-effects logistic regression models. Results – 1735 eligible patients were identified, 1672 (96%) injured from a blunt mechanism and 63 (4%) from a penetrating mechanism. For blunt mechanism trauma, 1250 (75%) were male and average age was 38 years (range: 15-94 years). TRISS information was available for 1565 patients of whom 204 (13%) died. Area under the Receiver Operating Characteristic (ROC) curves was 0.901 (95%CI: 0.879-0.923) for the TRISS(NZ) model and 0.890 (95% CI: 0.866-0.913) for TRISS (P<0.001). Insufficient data were available to determine coefficients for penetrating mechanism TRISS(NZ) models. Conclusions – Both TRISS models accurately predicted survival for blunt mechanism trauma. However, TRISS(NZ) coefficients were statistically superior to TRISS coefficients. A strong case exists for replacing TRISS coefficients in the New Zealand benchmarking software with these updated TRISS(NZ) estimates.

Infrastructure project planning decision making : challenges for decision support system applications

Most infrastructure projects share the same characteristics in term of management aspects and shortcomings. Human factor is believed to be the major drawbacks due to the nature of unstructured problems which can further contribute to management conflicts. This growing complexity in infrastructure projects has shift the paradigm of policy makers to adopt Information Communication Technology (ICT) as a driving force. For this reason, it is vital to fully maximise and utilise the recent technologies to accelerate management process particularly in planning phase. Therefore, a lot of tools have been developed to assist decision making in construction project management. The variety of uncertainties and alternatives in decision making can be entertained by using useful tool such as Decision Support System (DSS). However, the recent trend shows that most DSS in this area only concentrated in model development and left few fundamentals of computing. Thus, most of them were found complicated and less efficient to support decision making within project team members. Due to the current incapability of many software aspects, it is desirable for DSS to provide more simplicity, better collaborative platform, efficient data manipulation and reflection to user needs. By considering these factors, the paper illustrates four challenges for future DSS development i.e. requirement engineering, communication framework, data management and interoperability, and software usability
