Pengaruh Kinerja Hutang Terhadap Nilai Perusahaan Pada Perusahaan Pertambangan Batubara Yang Terdaftar Di BEI Periode 2010-2013
The primary goal of the company is to maximize firm value. Firm value is investor perceptionof the company\u27s success rate, it is often associated with stock prices. This research aim to examine the effect of leverage towards the value of the company in the coal mining companies which listed on the Indonesia Stock Exchange with periods 2010-2011. The hypothesis was leverage has negative effect on firm value. This research uses secondary data, of the coal mining companies which listed on BEI with periods 2010-2013. Research sample of 15 companies, where the method used is purposive sampling is a sampling method that takes an object with the specified criteria. Leverage are measured using Debt to Equity Ratio (DER) and Debt to Asset Ratio (DAR). Meanwhile, firm value is measured using Price Earning Ratio (PER). Analysis of the data used to analyze the factor that affect firm value is simple linier regression analysis and hypothesis test used the t-statistic for testing the partial regression coeffiecient at level of significant 5%. The results of this research finds leverage (DER) has negative significant effect on firm value (PER) with predictive ability is 6,8% and it shown by R square, and leverage (DAR) has negative significant effect on firm value (PER) with predictive ability is 7,2% and it shown by R square
Digital Transformation. Understanding Business Goals, Risks, Processes, and Decisions
Whilst digitisation is far from a new concept, many assume that simply introducing automation and information systems in various forms will be enough to make their organisation’s operations more efficient. This misconception can often lead to disarray and costly mistakes. Digital Transformation: Understanding Business Goals, Risks, Processes, and Decisions shows how to avoid such issues via careful consideration of what an enterprise really needs.
Unlike many other books on digital transformation, the authors do not dwell on database design or the details of implementing information systems. Instead, they emphasise the importance of a clear understanding of all aspects of an organisation in order to effectively implement and manage digital systems, from business goals and strategies to structuring information and making decisions, risk assessments, project management, organising, and procuring services and products.
Organised in eleven chapters, and drawing on examples from all over the world, this book will be of interest to university students of business administration, management, information systems, and computer science, as well as practitioners seeking to better understand how to handle digital transformation in their own organisation
Crohn's disease activity index and Vienna classification - Is it worthwhile to calculate before surgery?
Background: Crohn's disease (CD) patients with increased disease activity may reveal an increased risk for perioperative complications. The `Crohn's disease activity index' (CDAI) and the `Vienna classification' (VC) were developed for standardized disease activity estimations. The significance of these scores to predict extent, type and early outcome of surgery in CD patients was analyzed. Methods: In 179 surgically treated CD patients, the CDAI and VC were assessed from a prospective database. Relations of the scores with CD risk factors, type, number, location and complications of surgery were analyzed. Results: VC behavior and location subtypes were associated with distinct types of surgery (i.e. `strictureplasty' in `stricturing disease', `colon surgery' in `colon involvement'), but not with surgery type and extent or outcome. Surgery extent (i.e. with 5 vs. 3 `surgical sites' 425 +/- 25 vs. 223.3 +/- 25) and complications (357.1 +/- 36.9 (with) vs. 244.4 +/- 13 (without)) were associated with elevated CDAI levels; however, nicotine abuse remained the only significant risk factor for perioperative complications after multiple logistic regression. Conclusion: The significance of VC or CDAI for predicting the extent of surgery or complications is limited. None of the tested variables except preoperative nicotine abuse influenced the likelihood for perioperative complications. Copyright (c) 2006 S. Karger AG, Base

Towards a new understanding of HIV-related stigma in the era of efficient treatment- A qualitative reconceptualization of existing theory
Aim
To further develop Earnshaw and Chaudoir's HIV stigma framework by describing the experiences of HIV‐related stigma among people living with viral suppression in a context where HIV is well controlled and to investigate how these experiences correspond to the stigma mechanisms of the framework.
Design
Qualitative study using interviews and a framework approach to analysis.
Methods
People living with virally suppressed HIV in Sweden were recruited through an outpatient clinic and interviewed about their experiences of social aspects of living with HIV. The interviews were audio recorded, transcribed and analysed using a framework approach.
Results
Fifteen participants (eight women and seven men, aged 30–64 years) were interviewed from March to September 2017. They described stigma around HIV as a barrier in many situations. Anticipated and enacted stigma were found to be more complex than is described in the existing literature. Being labelled as a person with HIV was found to be an important and persistent part of the stigma experience. Disclosure was found to be context‐related and a result of a process of negotiating and weighing the relevance of disclosing HIV, perceiving HIV as a private matter and feeling a responsibility to disclose one's HIV status to others. An important reason for nondisclosure was to avoid being labelled with HIV, which would then become their most defining feature.
Conclusions
The HIV stigma framework could benefit from revision for people living with virally suppressed HIV.
Implications
The present findings, which indicate the role of health professionals in relation to disclosure and labelling, may guide nurses and other healthcare personnel in providing counselling and support for people who live with virally suppressed HIV and experience stigma

Psychometric properties of the EORTC QLQ-C30 in Uganda
BACKGROUND: Self-reported measures play a crucial role in research, clinical practice and health assessment. Instruments used to assess self-reported health-related quality of life (HRQoL) need validation to ensure that they measure what they are intended to, detect true changes over time and differentiate between subjects. A generic instrument measuring HRQoL adapted for use among people living with cancer in Uganda is lacking; therefore, this study aimed to evaluate the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 in patients with cancer in Uganda.
METHODS: Adult patients with various types of cancer (n = 385) cared for at the Uganda Cancer Institute answered the EORTC QLQ-C30 in Luganda or English language, the two most spoken languages in the country. The two language versions were evaluated with regard to data quality (floor and ceiling effects and missing responses), reliability (internal consistency) and validity (construct, known-group and criterion). Construct validity was examined through confirmatory factor analysis (CFA). Mean scores were compared between groups differing in disease stage to assess known-group validity. Criterion validity was examined according to associations between two QLQ-C30 subscales (Global quality of life and Physical function) and the Karnofsky Performance Scale (KPS).
RESULTS: Floor and ceiling effects were observed for several scales in the Luganda and English versions. All EORTC scales with the exception of Cognitive function (Luganda α = 0.66, English α = 0.50) had acceptable Cronbach's alpha values (0.79-0.96). The CFA yielded good fit indices for both versions (RMSEA = 0.08, SRMR = 0.05 and CFI = 0.93). Known-group validity was demonstrated with statistically significant better HRQoL reported by patients with disease stages I-II compared to those in stages III-IV. Criterion validity was supported by positive correlations between KPS and the subscales Physical function (Luganda r = 0.75, English r = 0.76) and Global quality of life (Luganda r = 0.59, English r = 0.72).
CONCLUSION: The Luganda and English versions of the EORTC QLQ-C30 appear to be valid and reliable measures and can be recommended for use in clinical research to assess HRQoL in adult Ugandans with cancer. However, the cognitive scale did not reach acceptable internal consistency and needs further evaluation

Health-related quality of life among adult patients with cancer in Uganda – a cross-sectional study
Objectives
The study aimed to investigate the prevalence and factors associated with poor health-related quality of life in adults with cancer in Uganda.
Methods
This cross-sectional study surveyed 385 adult patients (95% response rate) with various cancers at a specialised oncology facility in Uganda. Health-related quality of life was measured using the EORTC QLQ-C30 in the Luganda and English languages. Predetermined validated clinical thresholds were applied to the instrument in order to identify patients with poor health-related quality of life, that is, functional impairments or symptoms warranting concern. Multivariable logistic regression was used to identify factors associated with poor health-related quality of life in six subscales: Physical Function, Role Function, Emotional Function, Social Function, Pain and Fatigue.
Results
The mean age of the patients was 48 years. The majority self-reported poor functioning ranging between 61% (Emotional Function) to 79% (Physical Function) and symptoms (Fatigue 63%, Pain 80%) at clinically concerning levels. These patients were more likely to be older, without formal education and not currently working. Being an inpatient at the facility and being diagnosed with cervical cancer or leukaemia was a predictor of poor health-related quality of life.
Conclusion
Improvement of cancer care in East Africa requires a comprehensive and integrated approach that addresses various challenges specific to the region. Such strategies include investment in healthcare infrastructure, for example, clinical guidelines to improve pain management, and patient education and support services
Individual quality of life: adaptive conjoint analysis as an alternative for direct weighting?
In the schedule for the evaluation of individual quality of life (SEIQoL) the weights for five individualized quality of life domains have been derived by judgment analysis and direct weighting (DW). We studied the feasibility and validity of adaptive conjoint analysis (ACA) as an alternative method to derive weights in 27 cancer patients and 20 patients with rheumatoid arthritis. Further, we assessed the convergence between direct weights and weights derived by ACA, and their correlation with global quality-of-life scores. All respondents finished the ACA task, but one in five respondents were upset about the ACA task. Further, the task was vulnerable to judgment ‘errors’, such as inconsistent answers. The agreement between the two weights was low. Both weighted index scores were strongly correlated to the unweighted index score. The relationships between the index score and scores on a visual analogue scale for global individual quality of life and global quality of life were similar whether or not the index score was calculated with DW weights, with ACA weights, or without using weights. We conclude that, because weights did not improve the correlation between the index score and global quality of life scores, it seems sufficient to use the unweighted index score as a measure for global individual quality of life
Somatically ill persons’ self-nominated quality of life domains: review of the literature and guidelines for future studies
OBJECTIVE: To review which domains somatically ill persons nominate as constituting their QoL. Specific objective is to examine whether the method of enquiry affect these domains. METHODS: We conducted two literature searches in the databases PubMed/Medline, CINAHL and Psychinfo for qualitative studies examining patients' self-defined QoL domains using (1) SEIQoL and (2) study-specific questions. For each database, two researchers independently assessed the eligibility of the retrieved abstracts and three researchers subsequently classified all QoL domains. RESULTS: Thirty-six eligible papers were identified: 27 studies using the SEIQoL, and nine presenting data derived from study-specific questions. The influence of the method of enquiry on patients' self-nominated QoL domains appears limited: most domains were presented in both types of studies, albeit with different frequencies. CONCLUSIONS: This review provides a comprehensive overview of somatically ill persons' self-nominated QoL domains. However, limitations inherent to reviewing qualitative studies (e.g., the varying level of abstraction of patients' self-defined QoL domains), limitations of the included studies and limitations inherent to the review process, hinder cross-study comparisons. Therefore, we provide guidelines to address shortcomings of qualitative reports amenable to improvement and to stimulate further improvement of conducting and reporting qualitative research aimed at exploring respondents' self-nominated QoL domains
Role of Central Nervous System Glucagon-Like Peptide-1 Receptors in Enteric Glucose Sensing
OBJECTIVE—Ingested glucose is detected by specialized sensors in the enteric/hepatoportal vein, which send neural signals to the brain, which in turn regulates key peripheral tissues. Hence, impairment in the control of enteric-neural glucose sensing could contribute to disordered glucose homeostasis. The aim of this study was to determine the cells in the brain targeted by the activation of the enteric glucose-sensing system
