The Impact

Abstract Since the 1990s, the impact of late gestational nutrition and management on lactation and reproduction has become the focus of dairy management. Transition cow management has been credited with having greater influence on herd performance as compared to previous focus on lactation nutrition. Several seminal papers published in 1990s and early 2000s directed management practices of dry cows, rightly or wrongly, toward critical factors impacting calving and lactation. Dairy cow gestational protein requirements cited a 1956 study on Red Danish cows until Bell (1995) characterized the modern Holstein fetus’ chemical composition over the last 70 days of gestation. Recognized health effects of “fat cow syndrome”, similarly described for pigs, focuses late pregnant dairy cow management on body condition management starting in late lactation. Optimum condition was emphasized, recognizing negative impacts of excessive limited BC on lactation and reproduction. Maximizing dry matter intake was a nutritional goal for preventing energy-based metabolic challenges, until research indicated excessive energy during early, non-lactating period was more critical to managing postpartum metabolic derangements than the weeks prior to calving; which is like controlling energy intake of sows. Delivery of amino acids, estimated by metabolizable protein intake, has recently earned focus of research, relative to immune function, metabolic stability and reproductive success during early lactation. Identifying amino acids as critical fetal metabolic fuel, and consequences of excessive maternal protein mobilization, has become a focal point of swine and dairy transition nutrition. Although management of the transition cow has been greatly refined through nutritional research, improved cow performance has not yet been realized in the field. Recognition of the interplay between nutrition, environment and management relative to enhancing cow behavior has provided insight to the challenges of managing the transition cow. Metabolic, environmental and management challenges facing the physiologic transition from pregnancy into lactation occur in all production species. Although cows and sows procure essential nutrients by different digestive modes, cross-species applications can provide new or reinforcing perspectives on collective management approaches.

Abstract In this paper, we focus on inventory management in a manufacturing company in China. This study aims to identify the key factors that influence inventory management practices, investigate efficient and effective inventory management approaches, and examine the impact of supplier cooperation on supply chain improvement. A case study approach is used to identify the key factors that influence inventory management in a factory. Efficient and effective inventory management practices are derived from the case study and may provide practical guidance for foreign manufacturers in China. This study provides a valuable tool for identifying the key factors in inventory management which can be applied to similar problems encountered in actual manufactories.

In contemplating the extent to which rights-based litigation is conducive to positive social change, attention ought to be paid to the bureaucratic impact of court judgments that vindicate rights against the State. As a case study of such impact, this article considers the effects of human rights litigation on the regulation of informal trade in the City of Johannesburg, where a 2013 attempt by local government to clamp down on informal trade in the central business district (CBD) led to high-profile court action. After describing and problematising the City's general approach to managing informal trade, the article focuses on "Operation Clean Sweep", which aimed to rid much of the CBD of informal traders and became the focal point of rights-based resistance. It then briefly describes the constitutional and jurisprudential framework within which the legal challenge to "Operation Clean Sweep" was to be decided, before critically discussing the judgment of the Constitutional Court in South African Informal Traders Forum v City of Johannesburg 2014 4 SA 371 (CC), which effectively halted "Operation Clean Sweep" by interdicting the City from removing traders from their places of business. The article then proceeds to consider the aftermath of the judgment, and assesses its impact on the City's informal trade policy and urban management practices, as well as on the broader regulatory and political environment around street trade in South African cities. The article shows that the bureaucratic impact of the judgment has, at best, been mixed, and that the judgment has not been entirely successful in disrupting the legal and bureaucratic mindsets, frameworks and processes that simultaneously create, exacerbate and unsuccessfully attempt to address the "unmanageability" of street trade in Johannesburg.

The Impact

Totaling at 7.4 billion people, the world’s population is rapidly growing, bringing along with it an increase in waste generation. The impact of this exponential increase in waste generation has resulted in the increased formation and utilization of landfills. In the present day, landfills are utilized to dispose of chemical, hazardous, municipal, and electronic wastes. However, despite their convenience, most landfills are improperly managed and face constant changes from the surrounding environment that interfere with their internal landfill processes. The objectives of this mixed review are to highlight the negative impacts landfills have on the environment and public health as well as outline the need for proper management practices to mitigate these effects. Inadequate management of landfills leads to issues concerning leachate collection and landfill gas (LFG) generation, which give rise to groundwater contamination and air pollution. This paper recognizes the disadvantages of utilizing landfills as the main disposal method by focusing on these two primary effects that improper management of landfills has on the environment and human health. Many experts have also reported that communities within close proximity to improperly managed landfills have an increased risk of health issues. Apart from implementing proper landfill management practices, it is important to develop solutions to reduce waste generation altogether. This review discusses some of the innovative methods implemented by other countries to reduce landfill waste and the production of greenhouse gases as well as possible steps individuals can take to minimize their ecological footprints.

The Impact

Following the massive expansion of rubber plantations in China, considerable research has been conducted on the impact of these landscape changes. The general consensus is that there have been negative impacts on the environment and positive impacts on local economies. However, since rubber prices dropped after 2011, the economic benefit to the local people is challenged and the impact on the local people and communities remains unclear. Using a mix of qualitative and quantitative methods, this longitudinal study investigates how the drop in rubber prices has affected a local community and the local people in Manlin, Xishuangbanna, China. It investigates local coping strategies and the importance of alternative income sources and shows how differentiated access to alternative lands creates increased economic inequality within the village when prices fluctuate. Three general coping strategies were identified amongst local rubber farmers: doing business as usual, changing rubber management practices, and stopping- or decreasing tapping frequency. Differences in coping strategies are linked to factors including access to alternative income sources and rubber perceptions. Moreover, households with access to tea land were found to have experienced negligible impacts of decreasing rubber prices as income from tea has increased more than income from rubber has decreased, leading to increasing intra-village economic inequality. We conclude that while this is a clear case of how income diversification is important for reducing livelihood vulnerability, it also shows that the large focus on rubber farming has created benefits in terms of improved infrastructure and connectivity that has helped expand the market for tea as well.

AbstractHydrogen cyanide polymers – heterogeneous solids ranging in color from yellow to orange to brown to black – may be among the organic macromolecules most readily formed within the Solar System. The non-volatile black crust of comet Halley, for example, as well as the extensive orangebrown streaks in the atmosphere of Jupiter, might consist largely of such polymers synthesized from HCN formed by photolysis of methane and ammonia, the color observed depending on the concentration of HCN involved. Laboratory studies of these ubiquitous compounds point to the presence of polyamidine structures synthesized directly from hydrogen cyanide. These would be converted by water to polypeptides which can be further hydrolyzed to α-amino acids. Black polymers and multimers with conjugated ladder structures derived from HCN could also be formed and might well be the source of the many nitrogen heterocycles, adenine included, observed after pyrolysis. The dark brown color arising from the impacts of comet P/Shoemaker-Levy 9 on Jupiter might therefore be mainly caused by the presence of HCN polymers, whether originally present, deposited by the impactor or synthesized directly from HCN. Spectroscopic detection of these predicted macromolecules and their hydrolytic and pyrolytic by-products would strengthen significantly the hypothesis that cyanide polymerization is a preferred pathway for prebiotic and extraterrestrial chemistry.

The purpose of this study is to examine the impact of Shariah governance and corporate governance (CG) on the risk management practices (RMPs) of local Islamic banks and foreign Islamic banks operating in Malaysia. The Shariah governance comprises the Shariah review (SR) and Shariah audit (SA) variables. The study also evaluates the level of RMPs, CG, SR, and SA between these two type of banks. With the aid of SPSS version 20, the items for RMPs, CG, SR, and SA were subjected to principal component analysis (PCA). From the PCA, one component or factor was extracted each for the CG, SR, and RMPs while another two factors were extracted for the SA. Primary data was collected using a self-administered survey questionnaire. The questionnaire covers four aspects ; CG, SR, SA, and RMPs. The data received from the 300 usable questionnaires were subjected to correlation and regression analyses as well as an independent t-test. The result of correlation analysis shows that all the four variables have large positive correlations with each other indicating a strong and significant relationship between them. From the regression analysis undertaken, CG, SR, and SA together explained 52.3 percent of the RMPs and CG emerged as the most influential variable that impacts the RMPs. The independent t-test carried out shows that there were significant differences in the CG and SA between the local and foreign Islamic banks. However, there were no significant differences between the two types of the bank in relation to SR and RMPs. The study has contributed to the body of knowledge and is beneficial to academicians, industry players, regulators, and other stakeholders.
