A detailed MILP formulation for the optimal design of advanced biofuel supply chains
یک فرمول دقیق MILP برای طراحی بهینه زنجیره های پیشرفته تأمین سوخت زیستی-2021 The optimal design of a biomass supply chain is a complex problem, which must take into account multiple interrelated factors (i.e the spatial distribution of the network nodes, the efficient planning of logistics activities, etc.). Mixed Integer Linear Programming has proven to be an effective mathematical tool for the optimization of the design and the management strategy of Advanced Biofuel Supply Chains (ABSC). This work presents a MILP formulation of the economical optimization of ABSC design, comprising the definition of the associated weekly management plan. A general modeling approach is proposed with a network structure comprising two intermediate echelons (storage and conversion facilities) and accounts for train and truck freight transport. The model is declined for the case of a multi- feedstock ABSC for green methanol production tested on the Italian case study. Residual biomass feed- stocks considered are woodchips from primary forestry residues, grape pomace, and exhausted olive pomace. The calculated cost of methanol is equal to 418.7 V/t with conversion facility cost accounting for 50% of the fuel cost share while transportation and storage costs for around 15%. When considering only woodchips the price of methanol increases to 433.4 V/t outlining the advantages of multi-feedstock approach.© 2021 The Authors. Published by Elsevier Ltd.

Social movement activists’ conceptions of political action and counter-accounting through a critical dialogic accounting and accountability lens
تصورات فعالان جنبش اجتماعی از کنش سیاسی و مقابله با حسابداری از طریق یک دریچه حسابداری گفتگوی انتقادی و پاسخگویی-2021 In the face of growing disaffection with neoliberalism and corporate social and environmental
accounting, critical accounting recognizes the potential of counter-accounting to open spaces for
democratic contestation and to advance progressive change. Critical dialogic accounting and
accountability (CDAA), for example, views counter-accounting as providing social movements
with opportunities to challenge neoliberal hegemony, to mobilize multiple publics and to
construct new social realities. However, the democratizing potential of counter-accounting is
contested within academia, and social movements’ views of counter-accounting as a politicizing
practice are not well understood. We extend CDAA theorizing by elaborating on the value of
counter-accounting in advancing democratic struggles against neoliberalism and illustrating how
an agonistic lens can be useful in framing social movements’ actions in these struggles. Social
movements’ conceptualizations of political action and counter-accounting are empirically
investigated through interviews with 25 social movement activists. Based on the interviews and
our CDAA lens, we propose possible areas for critical accounting collaborations with social
movements as they seek to effect progressive change. keywords: حسابداری دیجیتالی انتقادی و پاسخگویی | مبنی بر حسابداری | عذاب | جنبش های اجتماعی | نئولیبرالیسم | Critical dialogic accounting and accountability | Counter-accounting | Agonistics | Social movements | Neoliberalism |

Pathophysiology of Advanced Heart Failure
پاتوفیزیولوژی نارسایی پیشرفته قلب-2021 The pathophysiologyof advanced heart failure (HF) can be characterized asa complex interplay ofdysregulated mechanisms comprising impaired hemodynamics, neurohormonal and proinflammatory
activation, dysfunctional cardiorespiratory reflex control, and inadequate energy handling, all of which
ultimately lead to multiorgan dysfunction; at the later stage of HF, numerous comorbidities, whose underlying pathophysiologiesoftenamplifyHFprogression,tendtodominatetheclinicalpicture and therapeutic approach, and some of these mechanisms have been identified as therapeutic targets in HF.
Blockade of the renin-angiotensin-aldosterone system (preferably with an angiotensin receptorneprilysin inhibitor, but alternatively with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers together with mineralocorticoid receptor antagonist) and sympathetic nervous system (with b-blockers) is now considered a fundamental element of pharmacologic therapy for all patients with advanced HF and reduced ejection fraction. Autonomic modulation (vagal nerve stimulation or baroreflex stimulation) in advanced HF tends to benefit functional variables (qualityof life,NewYork HeartAssociation class, 6-minutewalking distance), whereas improvement in the outcomes (total mortality, HF hospitalizations) still remains uncertain. Fluid overload with central and/or peripheral congestion characterize the clinical picture of advanced HF and is the main reason for hospital admission in these patients; distinction of different clinical patterns of congestion with different underlying mechanisms may improve the management of fluid overload in advanced HF. Recent clinicaltrials have shown that the following novel therapiestargeting impairedpathophysiologic pathways in advanced HF seem to improve patients’ outcomes: (1) vericiguat, a soluble guanylate cyclase stimulator; (2) omecamtiv mecarbil, a selective cardiac myosin activator; (3) sodium-glucose cotransporter 2 inhibitors; (4) ferric carboxymaltose, for patients with concomitant iron deficiency. Better understanding of the pathophysiology underlying HF progression may allow characterization of novel mechanisms that can be targeted in order to revert to a natural pathway of HF development and progression. |

The application of reusable learning objects (RLOs) in preparation for a simulation laboratory in medication management: An evaluative study
استفاده از اشیاء یادگیری قابل استفاده مجدد (RLOS) در آماده سازی یک آزمایشگاه شبیه سازی در مدیریت دارو: یک مطالعه ارزیابی-2021 To enhance the preparedness of undergraduate nursing and midwifery students to participate in the safe
provision of medication administration on their clinical placements, an innovative blended learning strategy
was designed and developed by the authors. The blended learning strategy included a suite of online reusable
learning objects specific to medication management theoretical knowledge and psychomotor skills to prepare students for a 90-minute practical face to face simulation laboratory session. Students identified that
the reusable learning objects had prepared them for the simulation laboratory session and was rated as a
productive learning experience. The blended learning strategy implemented to teaching and learning medication management to undergraduate nursing and midwifery students can positively influence students’
acquisition of knowledge and psychomotor skills to safely administer medications prior to their practice
placements in a clinical setting.

Emergency care providers perspectives of acute pain assessment and management in the prehospital setting, in the Western Cape, South Africa: A qualitative study
دیدگاه های ارائه دهندگان مراقبت های اورژانس ارزیابی درد و مدیریت درد حاد در محیط پیش دبستانی، در کیپ غربی، آفریقای جنوبی: یک مطالعه کیفی-2021 Introduction: A growing body of evidence suggests that pain knowledge and management are poor, perhaps more
so in the prehospital setting. The daily challenges that emergency care providers face in dealing with prehospital
pain remain unclear. This study aimed to gain a deeper understanding of acute prehospital pain assessment and
management in the Western Cape, South Africa.
Methods: A series of focus group discussions, using a constructivist paradigm and qualitative content analysis
were conducted.
Results: The key themes emerging from six focus groups (total 25 emergency care providers) related to the
difficulties of assessing pain in this setting, factors affecting clinical reasoning in this (hostile) setting, the re-
alities of prehospital pain care for non-advanced life support practitioners, along with emergency departments’
lack of understanding and appreciation of the prehospital environment, and participants’ suggestions to improve
pain practice.
Conclusion: Several barriers and enablers, some novel, to pain assessment and management in the South African
prehospital setting were identified. Our findings provide valuable insight and understanding of the challenges
related to pain care prehospital providers face, in other similar prehospital settings, but also to the global body of
knowledge on prehospital barriers and enablers of pain assessment and management. keywords: پیش بیمارستان | آمبولانس (مش) | خدمات اورژانس پزشکی (مش) | درد حاد (مش) | اندازه گیری درد (مش) | ضد درد (مش) | Prehospital | Ambulances (MeSH) | Emergency Medical Services (MeSH) | Acute pain (MeSH) | Pain Measurement (MeSH) | Analgesics (MeSH) |

Assessment of knowledge regarding tracheostomy care and management of early complications among healthcare professionals
ارزیابی دانش در مورد مراقبت از تراکئوستومی و مدیریت عوارض اولیه در میان متخصصان مراقبت های بهداشتی-2021 Introduction: Tracheostomy is commonly performed surgical procedure in ENT practice. Postoperative care is the most important aspect for achieving good patient outcomes. Unavailability of
standard guidelines on tracheostomy management and inadequate training can make this basic
practice complex. The nursing staff and doctors play a very important role in bedside management, both in the ward and in the intensive care unit (ICU) setup. Therefore, it is crucial that
all healthcare providers directly involved in providing postoperative care to such patients can
do this efficiently.
Objectives: The objective of this study is to assess the knowledge regarding identification and management of tracheostomy-related emergencies and early complications among healthcare professionals so as to improve practice and further standardization. Methods: Cross-sectional observational study included two hundred and fifty-four doctors and nurses from four large tertiary care hospitals. The questions used were simple and straightforward regarding tracheostomy suctioning, cuff care, cuff management, tube blockage, and feeding management in patients with tracheostomy. Results: Based on evidence from our study, knowledge level regarding tracheostomy care ranges from 48% to 52% with knowledge scores above 50% being considered satisfactory. Significant gaps in knowledge exist in various aspects of tracheostomy care and management among healthcare professionals. Conclusion: Our findings demonstrated an adequate knowledge level among health care professionals ranging from 48% to 52% with knowledge scores above 50% being considered satisfactory and revealed that gaps in knowledge still exist in various aspects of tracheostomy care and management. keywords: Tracheostomy | complications | Tracheostomy management | Knowledge | assessment |

Knowledge and behavior changes in clinician after training of partnership for Diabetes Control in Indonesia
دانش و رفتار تغییرات در پزشک پس از آموزش مشارکت برای کنترل دیابت در اندونزی-2021 Background and aims: One of the main determinants of successful diabetes management is the quality of
healthcare provider including general practitioner and internist which can be increased through medical
training. This study aimed to describe the changes of clinician’s knowledge and behavior of comprehensive diabetes management training program around Indonesia.
Method: We conducted a three-day training program for general practitioners and internists for 3.5
years, 2013 to 2016. All clinicians invited as voluntary participant to send their patient data from medical
record. Each participant was expected to submit a minimum of 25 type 2 diabetes (T2DM) set patient
data before and 6 months after training program to analyze the impact of program in physician
knowledge and behavior related to diabetes management.
Result: 120 of 489 voluntary participants submitted completed baseline data with 4676 patient data.
Meanwhile, only 32 participants that submitted completed data of 6 months before after training with
886 patient data. Most of parameters were improve before and after program. The greatest and lowest
improvement were on A1c measurement (21%) and smoking assessment (2%).
Conclusion: Intensive seminar and training was not enough to empower diabetes management. This
research might push the creation of clinical practice program that were tailored to each care facilities and
integrated within routine care aimed at continual improvement of its healthcare worker.

Optimal generic and brand advertising efforts in a decentralized supply chain considering customer surplus
تلاش بهینه تبلیغات عمومی و تجاری در یک زنجیره تأمین غیرمتمرکز با توجه به مازاد مشتری-2021 While the previous researches of advertising efforts decisions focus on only the firms’ profit target, no literatureintroduces corporation social responsibility target into advertising efforts decisions of a supply chain (SC). To fill this gap, we consider a two-stage SC with a manufacturer and a retailer where the SC members consider the customer surplus. Both the retailer and the manufacturer can invest in generic advertising efforts to influence and increase the products’ sales volumes. This paper investigates the following four scenarios: (1) The retailer cares the customer surplus (Model I); (2) The manufacturer cares the customer surplus (Model II); (3) Both the retailer and the manufacturer care the customer surplus (Model III); (4) We then extend the model III to the case that the manufacturer invests in both the generic and brand advertising efforts (Model IV). The objective of this paper is to determine the optimal retail price, the optimal advertising efforts, and the optimal profits of SC members, and find the influence of customer concern level on the SC performance. Finally, numerical examples are conducted to investigate the influence of the customer concern levels of the retailer or the manufacturer on the profits of the SC members and the entire SC. We also study the joint impacts of the customer concern levels of the retailer and the manufacturer on the SC performance. We find that the SC obtains the highest profits when the retailer’s customer concern level and the manufacturer’s customer concern level are relatively high, and the best cooperative strategy for the retailer and the manufacturer is that they improve customer concern level simultaneously.

Exploring the relationship between valuation and stewardship uses of accounting information: Empirical evidence from German listed firms
بررسی رابطه بین ارزش گذاری و استفاده از مباشرت از اطلاعات حسابداری: شواهد تجربی از شرکت های فهرست شده آلمانی-2021 While there is scarce empirical research on the relationship between valuation and stewardship uses of accounting information, existing studies on the basis of US data show a positive relationship. Motivated by recent analytical literature which suggests a contextspecific relationship, our study analyzes the relationship between valuation and stewardship uses in a non-US-setting, using data from German listed firms from 2006 to 2015. In
line with prior US studies, we find a positive relationship for Chief Executive Officer (CEO)
compensation in univariate analyses. However, the relationship does not remain positive
when considering firms’ extent of free float in multivariate analyses, which suggests that
firms’ governance structures affect the relationship. For non-CEO management board
members’ compensation, we find no significant valuation/stewardship relationship in univariate and multivariate analyses. This finding might reflect differences in managerial characteristics, such as risk aversion, between CEOs and non-CEO board members. Highlighting
the role of firm and managerial characteristics, our study offers more nuanced empirical
insights into the relationship of valuation and stewardship uses. Our findings also raise
doubts on whether the normative statement that valuation encompasses stewardship usefulness made by the International Accounting Standards Board (IASB) in its recent conceptual frameworks has empirical substance.

Self-management on heart failure: A meta-analysis
خود مدیریتی در نارسایی قلبی: متاآنالیز-2021 Background and aims: Heart failure (HF) is a severe public health problem all over the World. Selfmanagement is an effective method to progress self-care ability. However, the role of selfmanagement in heart failure has not been thoroughly elucidated.
Methods: The research articles related to heart failure were searched by the PubMed, Embase, Cochrane databases, and China National Knowledge Database on articles published through March 2020. The average 95% of confidence intervals (CIs) were used to calculate using random-effects or fixed-effects. Review Manager (version 5.2) was adopted for meta-analysis, sensitivity analysis, and bias analysis. Results: Eight (8) eligible studies with 1707 patients with HF were included in this analysis. In the Metaanalysis showed significant differences for Self-management (SM) groups in Dutch Heart Failure Knowledge Scale (DHFK) (MD ¼ 1.36, 95%CI [-0.03, 2.75], P ¼ 0.04; I2 ¼ 83%), in Self-Care of Heart Failure Index (SCHFI) (MD ¼ 5.51, 95%CI [0.62, 10.40], P ¼ 0.03; I2 ¼ 70%), and in Self-Efficacy for Managing Chronic Disease Scale (SEMCDI) (I2 ¼ 47%, Z ¼ 5.43, P of over effect < 0.0001) than control groups. One bias is detected as attrition bias, and another one is reporting bias. Sensitivity analysis satisfied the stability of the results. Conclusion: Self-management was associated with significant outcomes in patients with HF through knowledge, attitude, and practice (KAP). keywords: نارسایی قلبی | خود مدیریت | می شود | متاآنالیز | Heart failure | Self-management | KAP | Meta-analysis |
