Micro-enterprise development initiatives and entrepreneurial competencies,innovativeness, and social capital in Malaysia

This article examines the effect of participation in development programmes designed for women micro-entrepreneurs on the development of entrepreneurial competencies, innovativeness, and social capital. The study employed a cross-sectional design and quasi-experimental approach, and collected data from 417 women micro-entrepreneurs in Malaysia. Findings reveal that the participants possess a significantly higher level of social capital, innovativeness, and entrepreneurial competencies. Development organisations should therefore focus on redesigning their policies and programmes to improve the breadth and depth of the development programmes that they offer, which ultimately lead to an improvement in the social-economic condition of low-income households in Malaysia.     

Policy networks,networks and European Union policy making: A sceptical view

The policy network approach and the networks model are the most recent conceptual frameworks to be applied to the policy‐making processes of the European Union and are regarded by many as the most appropriate. This article, while acknowledging their appeal, puts forward a sceptical view about the usefulness of their application to the EU. Three contentions are advanced about these approaches: first, that the fluidity of EU processes eludes their capture; second, that they are insufficiently sensitive to the EU's institutional complexity and fail to recognise the importance of EU institutions; and third, that they underestimate the difficulty of delineating networks involving the EU.¹     

Isolation and identification of an isomeric sildenafil analogue as an adulterant in an instant coffee premix

The proliferation of adulterated health foods and beverages in the market demands a comprehensive analytical strategy to identify the adulterants, particularly those of isomeric phosphodiesterase 5 (PDE5) inhibitors. An instant coffee premix (ICP) purchased from an online retailer was flagged for suspected adulteration through PDE5 inhibition assay. The ICP was then analysed using suspected-target and non-targeted screenings of a liquid chromatography-quadrupole time-of-flight mass spectrometry. Based on these findings, a PDE5 inhibitor initially assigned as compound X was isolated from the ICP by employing a liquid chromatography-diode array detection before its structural elucidation with liquid chromatography-ultraviolet (LC-UV) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy. The suspected-target screening matched the protonated molecule ([M + H]⁺) precursor ion of compound X at m/z 499.2310 with two suspected analytes that are structural isomers of one another. The fragmentation patterns of compound X were comparable to those analogues in the dithiocarbodenafil group through the non-targeted screening. These findings, complemented by the LC-UV and NMR spectroscopy data, together with the chromatographic separation of related structural isomers, conclude the identity of compound X. To our best knowledge, this is the first study to report the presence of 3,5-dimethylpiperazinyl-dithiodesmethylcarbodenafil in an ICP sample.

Key points

• The herbal-based male sexual performance products’ lucrative market has instigated their rampant adulteration, particularly with PDE5 inhibitors.
• The adulterated products may also contain analogues of the approved PDE5 inhibitors, which usually passed into the market undetected as they are not included in the routine targeted screening procedure.
• The present study detected, isolated, and identified an isomeric sildenafil analogue from an instant coffee premix sample using rapid qualitative assay and comprehensive analytical analysis.
• This paper highlighted the applicability of the established strategies for routine casework, particularly in a forensic drug testing laboratory.

     

Eristalinus arvorum (Fabricius, 1787) (Diptera: Syrphidae) in Human Skull: A New Fly Species of Forensic Importance

A body of an unknown adult female was found within a shallow burial ground in Malaysia whereas the skull was exposed and visible on the ground. During autopsy examination, nine insect larvae were recovered from the interior of the human skull and subsequently preserved in 70% ethanol. The larvae were greyish in appearance, each with a posterior elongated breathing tube. A week after the autopsy, more larvae were collected at the burial site, and some of them were reared into adults. Adult specimens and larvae from the skull and from the burial site were sequenced to obtain DNA barcodes. Results showed all adult flies reared from the burial site, as well as the larvae collected from the skull were identified as Eristalinus arvorum (Fabricius, 1787) (Diptera: Syrphidae). Here, we report the colonization of E. arvorum larvae on a human corpse for the first time.     

Short run and long run effects of the world crude oil prices on the Malaysian natural rubber and palm oil export prices

With regard to the increasing in world crude oil prices, it is time to examine more carefully the claim that the increase in world crude oil prices tends to increase commodity prices. Hence, we examine the major commodity prices in Malaysia namely palm oil prices and natural rubber prices. We will analyse the relationship of both commodities＇ prices with world crude oil prices using the autoregressive distribution lag （ARDL） approach. Besides the analysis of bound testing approaches to see the level of relationships, short run and long run effects also are carried out in order to investigate which period has been significantly effected by the increase of world crude oil prices. The result reveals that long run relationship between world crude oil prices and both commodities prices exists.     

Yarmouk,Jordan, and Disi basins: Examining the impact of the discourse of water scarcity in Jordan on transboundary water governance

Extensive literature has shown the impact of water scarcity discourses on national policies, however the impact of water scarcity discourses on transboundary water governance has been overlooked. This article contributes to filling this gap by investigating the impact of the water scarcity discourse in the case of Jordan, specifically on three cases of transboundary water governance: the Yarmouk River, the Jordan River and the Disi Aquifer. This article shows that the water scarcity discourse is not enough to explain transboundary water governance, as it needs to be contextualized in the broader context, considering national security, regional geopolitics, inter-sectorial interests, and power asymmetries. This is particularly true when considering that the Arab region has most of its surface waters originating outside of its countries, and transboundary waters represent over two thirds of its overall water resources.
