Pendekatan Qspm Sebagai Dasar Perumusan Strategi Peningkatan Pendapatan Asli Daerah Kabupaten Batang, Jawa Tengah

The aim of this research is to analyse of increasing Local Original Income (LOI) strategy and his influence to increasing the regional income. The research was done at Local Government Income of Batang regency. This research also want to know that the LOI strategy was based on the potencies and opportunities. The analyzing use the IFE, EFE, SWOT, and then QSPM to choose strategic formulation; and proportion models. The result of Internal – External analysis show that increasing strategy of LOI have not based on the potencies and opportunities that they have yet. The Local Government Income of Batang Regency needs the intensification strategy for increasing the LOI. By the QSPM analysis, the Local Government Income of Batang Regency needs extensification strategy for LOI acceptance

Monomeric Platinum(II) Hydroxides Supported by Sterically Dominant α-Diimine Ligands

The use of two new highly sterically bulky α-diimine ligands for the stabilization of neutral, monomeric platinum­(II) hydroxo complexes is described. Halide abstraction from LPtCl₂ complexes of these ligands in the presence of water, followed by deprotonation of the cationic aquo complex, leads to LPt­(OH)Cl and LPt­(OH)₂. The latter can be reprotonated with HNTf₂ to yield a highly fluxional hydroxoaquoplatinum­(II) cation

β-Elimination-Immune PC_carbeneP Iridium Complexes via Double C–H Activation: Ligand–Metal Cooperation in Hydrogen Activation

The synthesis of two members of a new PCP pincer ligand family and their complexation with iridium has been developed. Double C–H activation results in a ligand anchored by a carbene donor; hydrogen reversibly adds to the (PC_carbeneP)­IrCl complexes <b>3</b>^<b>R</b> (R = ⁱPr, ^tBu). Aryl, amido, and phenoxy derivatives are available from the chlorides via salt metathesis. These compounds add H₂ and eliminate H–X; the iridium compound is trapped as a PC_alkylP iridium polyhydride

Unexpected Anomeric Selectivity of a 1-<i>C</i>-Arylglycal Donor in Kdo Glycoside Synthesis

A novel class of 1-<i>C</i>-arylglycals was developed and subjected to <i>N</i>-iodosuccinimide-mediated glycosylations with alcohols. Unexpectedly, all reactions provided 2-iodo-β-d-ketopyranosides in high yields and excellent stereoselectivity. After removal of the 2-iodide by radical conditions, the aryl group was smoothly oxidized to provide the corresponding β-Kdo glycosides. A mechanism for the stereoselective formation of β-d-ketopyranosides was proposed, which was supported by evidence from X-ray crystallography

An Empirical Analysis of Pruning Techniques: Performance, Retrievability and Bias

Prior work on using retrievability measures in the evaluation of information retrieval (IR) systems has laid out the foundations for investigating the relation between retrieval performance and retrieval bias. While various factors influencing retrievability have been examined, showing how the retrieval model may influence bias, no prior work has examined the impact of the index (and how it is optimized) on retrieval bias. Intuitively, how the documents are represented, and what terms they contain, will influence whether they are retrievable or not. In this paper, we investigate how the retrieval bias of a system changes as the inverted index is optimized for efficiency through static index pruning. In our analysis, we consider four pruning methods and examine how they affect performance and bias on the TREC GOV2 Collection. Our results show that the relationship between these factors is varied and complex - and very much dependent on the pruning algorithm. We find that more pruning results in relatively little change or a slight decrease in bias up to a point, and then a dramatic increase. The increase in bias corresponds to a sharp decrease in early precision such as NDCG@10 and is also indicative of a large decrease in MAP. The findings suggest that the impact of pruning algorithms can be quite varied - but retrieval bias could be used to guide the pruning process. Further work is required to determine precisely which documents are most affected and how this impacts upon performance

Synthesis and Reactivity of a Terminal Scandium Imido Complex

Preparation of a terminal scandium imido complex, <b>2</b>·DMAP, was accomplished through thermolysis of an arylamido methyl complex, <b>1</b>, stabilized by a bulky β-diketiminato ligand in the presence of 4-<i>N</i>,<i>N</i>-dimethylaminopyridine (DMAP). Mechanistic studies revealed that the reaction proceeds by initial metalation of <b>1</b>, followed by rapid DMAP-promoted alkane elimination to generate the scandium imido complex. Kinetic studies of the reaction between separately synthesized metalate <b>3</b> and DMAP under pseudo-first-order conditions yielded activation parameters of Δ<i>H</i>^⧧ = 73.5(2) kJ mol^–1 and Δ<i>S</i>^⧧ = −70.4(5) J K^–1 mol^–1. The reaction of <b>2</b>·DMAP with <i>tert</i>-butyl amine or phenylacetylene resulted in addition of the N–H or C–H bond across the scandium imide linkage, respectively, to furnish complexes <i>endo-</i>/<i>exo</i><b>-4</b> and <i>endo</i><b>-5</b>. These compounds were fully characterized, including via structural analysis, providing further evidence for the terminal scandium imido derivative <b>2</b>·DMAP
