41 The performance effects of gender diversity on bank boards
تاثیرات عملکردی تنوع جنسیتی روی هیئت های بانکها-2018
Previous literature has shown mixed results on the role of female participation on bank boards and bank performance: some papers find that more women on boards enhance financial performance, while others find negative or no effects. Applying instrumental variables methods to data on approximately 90 U.S. bank holding companies over the 1999–2015 period, we argue that these inconclusive results are due to the fact that there is a non-linear, U-shaped relationship between gender diversity on boards and various measures of bank performance: female participation has a positive effect once a threshold level of gender diversity is achieved. Furthermore, this positive effect is only observed in better capitalized banks. Our results suggest that continuing the voluntary expansion of gender diversity on bank boards will be value-enhancing, provided that they are well capitalized.

42 داده های مربوط به غلظت فلوراید و ارزیابی ریسک بهداشت آب آشامیدنی استان خراسان رضوی
سال انتشار: 2018 - تعداد صفحات فایل pdf انگلیسی: 6 - تعداد صفحات فایل doc فارسی: 8
در حالی که فلوراید (F) آنیون ضروری برای حفظ سلامت بدن انسان است، مصرف زیاد فلوراید می تواند منجر به مشکلات جدی سلامتی شود. نظارت بر میزان فلوراید آب آشامیدنی در مسیر اصلی مصرف فلوراید ، یک عامل کلیدی در پیشگیری از پیامدهای منفی بهداشتی آن است. در این مقاله به سطوح فلوراید در شبکه های توزیع آب آشامیدنی استان خراسان رضوی دسترسی داریم که طی 2016 تا 2017 جمع آوری شده است. محاسبه خطر ابتلا به سرطان ناشی از فلوراید در مناطق شهری و روستایی نیز با محاسبه¬ی مصرف روزانه مزمن (CDI) و فاکتور خطر (HQ) برای بزرگسالان و کودکان انجام شد. نمونه برداری از شبکه توزیع آب آشامیدنی در 112 منطقه مختلف خراسان رضوی صورت گرفت و غلظت فسفر ، با روش استاندارد SPADNS تعیین شد. حداقل سطح فلوراید در نمونه های شهرداری و روستایی به ترتیب 0.09 و 0.16 میلی گرم در لیتر، حداکثر آن نیز به ترتیب 1.7 و 1.1 و میانگین آن به ترتیب 0.74 و 0.59 میلی گرم در لیتر است. میانگین مقادیر میانگین CDI فلوراید در نمونه های شهری برای مردان، زنان و کودکان به ترتیب 2-10 × 1.3، 4-10 × 3.34 و 6-10 × 6.56 میلی گرم/کیلوگرم/ روز بدست امد. CDIبرای نمونه های روستایی به ترتیب برای مردان، زنان و کودکان به ترتیب2-10 × 1.51، 4-10 × 3.34 و 6-10 × 8.56 میلی گرم/کیلوگرم/ روز بدست آمد. میانگین HQ فلوراید برای مردان، زنان و کودکان در نمونه های شهری و روستایی به ترتیب 1-10 × 2.17، 3-10 × 5.56 ، 4-10 × 1.43 و 1-10 × 2.44، 3-10 × 6.26 ، 4-10 × 1.61 است. به منظور جلوگیری از خطرات بالقوه سلامتی در مناطق دارای HQ>1 به استراتژی مناسب برای کاهش سطح فلوراید آب آشامیدنی نیاز است.

43 The dark triad and knowledge hiding
سه گانه تاریک و پنهان کردن دانش-2018
By drawing on psychological contract theory, this study examined the effects of the dark triad of personality traits (Machiavellianism, narcissism, and psychopathy) on knowledge hiding within organizations. We obtained 251 matched-pair data from respondents in a manufacturing company. Results showed that all three dimensions of the dark triad were positively related to knowledge hiding through transactional psychological contract. Different dimensions of the dark triad were most strongly related to different knowledge hiding strategies. Furthermore, gender moderated the relationships between narcissism and psychopathy with transactional psychological contract. The indirect relationships between narcissism and psychopathy with knowledge hiding via transactional psychological contract were stronger for men than women.

44 Media coverage of the Zika crisis in Brazil: The construction of a ‘war’ frame that masked social and gender inequalities
پوشش رسانه ای از بحران زیکا در برزیل: ساخت یک فریم جنگی که نابرابری های اجتماعی و جنسیتی را تحت پوشش قرار داد-2018
Between 2015 and 2016, Zika became an epidemic of global concern and the focus of intense media coverage. Using a hybrid model of frame and social representations theory, we examine how the Zika outbreak was re ported in two major newspapers in Brazil: O Globo and Folha de São Paulo. The analysis of 186 articles published between December 2015 and May 2016 reveals a dominant ‘war’ frame supported by two sub-frames: one focused on eradicating the vector (mosquito) and another on controlling microcephaly, placing the burden of prevention on women. Scientific uncertainties about the virus and its relationship to microcephaly coupled with political uncertainties in Brazil increased the power of the war frame. This frame gave prominence and legiti macy to certain representations of disease management during the crisis, masking social and gender inequalities. We show how the cartography of the disease overlaps with that of poverty and regional inequality in Brazil to argue that addressing socio-economic aspects is essential, but normally neglected, in media communications during disease outbreaks like Zika.

45 رابطه بالقوه سببی- تاثیری بین نشانگان خودایمنی انسولینی و آلفا لیپوئیک اسید: دو گزارش موردی
سال انتشار: 2018 - تعداد صفحات فایل pdf انگلیسی: 4 - تعداد صفحات فایل doc فارسی: 12
اهداف: نشانگان خودایمنی انوسلین (IAS) یا بیماری هیراتا یک علّت نادر برای کاهش قند خون در خودایمنی می باشد که با سطوح بالای انسولین و خود-پادزهرهای ضد انسولین همراه است و اولین بار توسط هیراتا در ژاپن درسال 1970 توصیف شد. موارد بیماری IAS معمولا" به قرار گرفتن درمعرض داروهای حاوی سولفیدریل مربوط می شود که تولید پادزهرهای انسولین را تحریک می کنند. دربین ترکیبات حاوی سولفیدریل، آلفا لیپوئیک اسید (ALA) اخیرا" به عنوان یک علت برای IAS پدیدار شده است. پس از اینکه اولین مشاهدات IAS تحریک شده توسط ALA در ژاپن در سال 2006 گزارش شد، تعداد روزافزونی از موارد مربوط به کنترل ALA توصیف شده است. یک گروه ایتالیایی اخیرا" شش مورد از IAS را گزارش کرده اند که یکی از آنها با HLA-DRB1*04:06 و بقیه آنها با HLA-DRB1*04:03 همراه بود. این بیانگر این است که مورد دوم به صورت بالقوه ای در آسیب پذیری ژنتیک مردم اروپا که IAS را به ارث برده اند دخیل است.
روشها: دراینجا ما دو مورد جدید از IAS را در زنان توصیف می کنیم که توسط ALA ایجاد شده بودند.
نتایج: هردومورد با HLA-DRB1*04:03 همراه بودند و تایید کننده این مدعا بودند که HLA-DRB1*04:03 بیشتر از HLA-DRB1*04:06 به صورت ویژه ای با آسیب پذیری مردم اروپا دربرابر IAS ارتباط دارد.
نتیجه گیری ها: موارد گزارش شده از حوادث کاهش قند خون که توسط LAL تحریک شده اند، روی نیاز به مراقبت بیشتر در تجویز داروهای مکمّل ALA و نیز شناسایی اهداف درمانی خاص و فردی، تاکید دارند.

46 Solving the crisis: When agency is the preferred leadership for implementing change
حل بحران. وقتی آژانس رهبری مطلوب برای اجرای تغییر است-2018
Glass-cliff research shows that female leaders are preferentially selected in a crisis to signal change and not for their leadership qualifications. In parallel, the management literature urges for agentic “masculine” leadership to turn around organizations in crisis. We hypothesized that, regardless of their gender, agentic leaders should be preferred to communal leaders if leadership qualifications and actual change potential motivate leader selection. Three experimental studies demonstrated that agentic (vs. communal) candidates were perceived to match poorly-performing (vs. strongly-performing) companies. This effect was accounted for by perceptions of agentic candidates higher suitability, higher task-orientation (versus person-orientation), and higher change potential. We discuss that women face ambiguity as to why they become leaders in crisis contexts: because they are perceived as signaling change, stereotypically linked to their gender, or for their perceived agentic qualities as leaders. In contrast, men become crisis leaders due to their perceived agentic change potential.

47 On the effects of perceived value in the mobile moment
تاثیرات ارزش مشاهده شده در لحظه سیار-2018
Given that mobile phone photography has increased dramatically in popularity, people’s social networking behaviors are becoming more and more visual. Numerous image-based applications and social media are taking advantage of this growing popularity of visual content viewing, editing, and sharing, creating a new phenomenon, image-based social networking. Many image-based social apps are developed as multi-purpose systems, offering a variety of kinds of value to their users. This study proposes three kinds of mobile value – hedonic, utilitarian and sociability – to measure users’ perceptions of image-based apps, and explores how the three kinds of value impact user satisfaction and long-term behavioral intentions. The proposed model was empirically validated using a field survey of 500+ respondents. Both hedonic and sociability value can be provided by an image-based app, but not the utilitarian value, which can increase users’ willingness to pay. The resulting knowledge supports the understanding of various kinds of value by pointing out their different effects on continuance intention and willingness-to-pay. The results also indicate that men and women are affected by different kinds of mobile value when considering using an image-based app. The value that men perceive from an image-based app is generally lower than that perceived by women. Because the value configuration of an app will characterize its market position, the research findings provide implications for app vendors to develop their marketing strategy and to design the best monetization model based on the value configuration of their products.

48 Perioperative Management of Pregnant Women With Idiopathic Pulmonary Arterial Hypertension: An Observational Case Series Study From China
مدیریت بعد از عمل زنان باردار مبتلا به ایدیوپاتیک ریوی فشار خون شریانی: مطالعه موردی مورد بررسی از چین-2018
Objectives: The mortality of pregnant women with idiopathic pulmonary arterial hypertension (PAH) is very high. There are limited data on the management of idiopathic PAH during pregnancy. The authors aimed to examine systematically the characteristics of parturient women with idiopathic PAH, to explore the adverse effects of idiopathic PAH on pregnancy outcomes, and to report the multidisciplinary perioperative management strategy from the largest comprehensive cardiac hospital in China. Design: Observational case series study. Setting: Tertiary referral acute care hospital in Beijing, China. Participants: The cases of 17 consecutive pregnant idiopathic PAH patients undergoing abortion or parturition at Anzhen Hospital were reviewed retrospectively. Interventions: Preoperative characteristics, anesthesia method, intensive care management, PAH-specific therapy, and maternal and neonatal outcomes were analyzed in this case series study. Measures and Main Results: Maternal and neonatal outcomes were the main measures. The mean ages of the 17 parturient women with idiopathic PAH were 28.3 7 5.4 years, and the mean systolic pulmonary arterial pressure was 97.9 7 18.6 mmHg. Fifteen patients (88.2%) received PAH-specific therapy before delivery, including sildenafil, iloprost, and treprostinil. All except 1 parturient received epidural anesthesia for surgery due to an emergency Caesarean section. Three patients experienced pulmonary hypertension crisis that necessitated conversion to general anesthesia. Ten parturients underwent Caesarean delivery at a median gestational age of 31 weeks. Three patients developed acute pulmonary hypertensive crisis intraoperatively. Two patients underwent cardiopulmonary resuscitation and extracorporeal membrane oxygenation support. The maternal mortality was 17.6% (3/17). Of the 10 delivered neonates, 9 (90.0%) survived. Conclusions: The maternal mortality of the idiopathic PAH parturient was high in this case series from China. The authors applied epidural anesthesia, early management with multidisciplinary approaches, PAH-specific therapy, avoidance of oxytocin, and timely delivery or pregnancy termination to improve maternal and neonatal outcomes.

49 Retro-peritoneal paraganglioma, diagnosis and management
paraganglioma یکپارچه صفاقی، تشخیص و مدیریت-2018
Introduction. — Paragangliomas, defined as extra-adrenal chromaffin-cells tumors, are rarely located in the retro-peritoneum. Clinical presentation is similar to pheochromocytoma, and mainly depends on the producing character of the tumor. Positive diagnosis requires plasmatic and urinary hormonal assays. Radiological and isotopic explorations are essential before surgery. The only curative therapeutic strategy is surgical, associated to peri-operative prevention and monitoring of the frequently reported hemodynamic and cardiovascular disorders. Outcome depends of the metastatic character of the tumor, the presence of tumor remnant after surgi cal resection. Genetic study is recommended; the risk of recurrence and association to other neoplasm is more described in genetic forms. Material and methods. — Authors report 5 cases of retro-peritoneal paraganglioma, operated in the department of urology of Hospital, between 2013 and 2017. Observations are about 2 men and 3 women. Clinical presentation is not always specific and paraganglioma may be discovered fortuitously. Two patients have been operated by coelioscopic approach, midline incision was performed in two other cases, and dorsal lumbotomy associated to a Rutherford Morrison incision in a patient.

50 Female board directorship and firm performance: What really matters?
ریاست هیئت زنان و عملکرد شرکت: چه چیزی واقعا اهمیت دارد؟-2018
Using a sample of 394 French firms for the period of 2001 to 2010, we study the relationship between female directorship and firms’ accounting (ROA and ROE) and market-based (Tobins Q) performance. We find that female directorship significantly increases ROA and ROE, and significantly decreases Tobins Q. We postulate that these relationships are affected by the attributes of female directors. To this end, we collect a set of nine different attributes of female directors capturing their monitoring capabilities and contribution to the boards human capital (demographic and board relational attributes). We find that the positive relationship between accounting performance and female directorship remains when we include these attributes, while the negative relationship between Tobins Q and female directorship disappears. Interestingly, the different attributes of female directors do not uniformly affect accounting and market-based performance. We explain the different relationships between attributes and firm performance by the tradeoff between the benefits and costs of diversity on board effectiveness, particularly in a low investor protection environment.
