Cultural values and demographic correlates of citizenship performance

This study examines the impact of cultural values on citizenship performance (CP) in the context of a developing country. Although differences in CP across cultures have been examined, the situation in developing countries is often not clear. Using a sample of 362 Sri Lankan employees, it is found that gender and education have significant impact on CP. While collectivism, future orientation, and uncertainty avoidance are found to be positively related to CP, power distance and masculinity values are negatively correlated with CP. It is also evident that the same cultural value orientation can have both positive and negative impacts on CP, depending on the particular aspect of CP. The findings reveal that developing countries are not totally different from developed countries as far as the impact of cultural values on CP is concerned. The study contributes to the advancement of CP theories of individual differences and cultural values and relevant knowledge pertaining to developing countries. Implications of findings are discussed and suggestions are offered for further research

Meta-analysis of Technical Efficiency in Selected Agricultural Sub-sectors: Implications for Policy Making in Developing Countries like Sri Lanka

Aims: To evaluate the technical efficiency (TE) in selected agricultural sub-sectors and to propose possible policy interventions to the government with the aim of reducing the poverty of farmers in the developing world. Study design: A meta-analysis based on empirical studies conducted by various scientists throughout the developing world. Methodology: Research articles for the meta-analysis were selected using a thorough screening process based on the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) concept. Selected 94 articles were sub-divided in to three main agriculture sub-sectors for detailed analysis; (a) paddy, other field crops-OFC and vegetables, (b) fruits, and (c) livestock. Mean TE of each crop or livestock type was calculated by averaging the TE values for a particular crop or livestock type across different studies included in this study. Results: TE data presented in the original articles showed a considerable dispersion within a given study. The highest mean TE was recorded in B-onion (0.83±0.15) whereas the lowest was recorded in maize (0.703±0.09) and in soybean (0.705±0.13). The TE of chili cultivation was 0.78 with the greatest variability (standard error of mean [SEM] 0.19) among the crops considered, which signifies the unpredictable nature of the chili cultivation. Mango was found to be the least technically efficient crop among the studied, with a mean TE of 0.596±0.11. Dairy, poultry and aquaculture farming operations were found to be highly technically efficient having mean TE values of 0.80±0.16, 0.89±0.02 and 0.88±0.08 respectively. Conclusion: Findings of this study will lead to several key policy implications including, improvement of the socioeconomic characteristics of farmers, implementation of farmer field schools (FFS) and establishment of a cautious and gradual strategy for expansion of the rural financial institutions

Of the total variance, 92 % is explained by PC1, which is a size axis (although the highest factor loading was for SVL, all other variables too, had high positive values); &lt;i&gt;Lankanectes pera&lt;/i&gt; &lt;b&gt;sp. nov.&lt;/b&gt; is larger in size than &lt;i&gt;L. corrugatus&lt;/i&gt; (see Appendix 4 for all material studied and measurements). Only 2.6% of the total variance is explained by PC2, which reflects mostly in FLI (length of first finger) and NS (nostril to snout distance). This axis, however, is uninformative as the two species show nearly complete overlap (Fig. 1D, Appendix 4).&lt;/p&gt; &lt;p&gt; &lt;b&gt;Distribution:&lt;/b&gt; &lt;i&gt;Lankanectes pera&lt;/i&gt; &lt;b&gt;sp. nov.&lt;/b&gt; is restricted to streams flowing through the montane forests on highest peaks of the Knuckles Mountain range&mdash; 1100 m asl, in Dothalugala and Bamabarella and Riverston regions.&lt;/p&gt; &lt;p&gt; &lt;b&gt;Ecological notes and natural history.&lt;/b&gt; This species has so far only been observed inhabiting pristine streams flowing through closed-canopy montane forests. These streams are characterized by clear, shallow and slowflowing water, and sand and rock-strewn substrates. Males are found under rocks or rock-crevices in flowing water. Occasionally males call haltingly during daytime, but several males frequently vocalize in chorus at night, especially after light rain. Tadpoles of these frogs are large (total length of Gosner stage 35 tadpoles range between 42.00&ndash; 45.14 mm, &lt;i&gt;N =&lt;/i&gt; 4), and occur in deeper regions (0.5 m) where decaying vegetation gathers.&lt;/p&gt;Published as part of &lt;i&gt;Senevirathne, Gayani, Samarawickrama, V.

Anatomical landmarks for ankle block

Abstract We aimed to describe anatomical landmarks to accurately locate the five nerves that are infiltrated to accomplish anaesthesia of the foot in an ankle block. Twenty-four formaldehyde-fixed cadaveric ankles were studied. Photographs of cross sections of the frozen legs, cut at a horizontal plane across the most prominent points of the medial and lateral malleoli, were analysed. The curvilinear distance from the most prominent point of the closest malleolus to each of the five cutaneous nerves and their depth from the skin surface were measured. Sural, tibial, deep peroneal, saphenous and medial dorsal cutaneous nerves were located 5.2 ± 1.3, 9.2 ± 2.4, 7.4 ± 1.9, 2.8 ± 1.1, 2.1 ± 0.6 mm deep to the skin surface. The curvilinear distances from the medial malleolus to the tibial, deep peroneal and saphenous nerves were 32.5 ± 8.9, 62.8 ± 11.1 and 24.4 ± 7.9 mm, respectively. The curvilinear distances from the lateral malleolus to the sural and medial dorsal cutaneous branches of superficial peroneal nerves were 27.9 ± 6.3 and 52.7 ± 7.3 mm, respectively. The deep peroneal nerve was found between the tendons of the extensor hallucis longus and the extensor digitorum longus in the majority of specimens, while the medial dorsal cutaneous nerve was almost exclusively found on the extensor digitorum longus tendon. The sural and tibial nerves were located around halfway between the most prominent point of the relevant malleolus and the posterior border of the Achilles tendon. In conclusion, this study describes easily identifiable, palpable bony and soft tissue landmarks that could be used to locate the nerves around the ankle
