The purpose of this paper is to develop an understanding about the internal fraud and corruption problem in the Turkish construction industry. The reasons behind the internal fraud and corruption problem as well as the types of prevention methods were investigated; and as a result various recommendations were made. To this end, a risk awareness questionnaire was used to understand the behavioral patterns of the construction industry, and to clarify possible proactive and reactive measures against internal fraud and corruption. The (...) type of fraud experienced by Turkish construction companies was also surveyed in the questionnaire. The questionnaire was sent to 89 firms; and depending on the collected data, certain recommendations for construction industry professionals were provided. (shrink)

In this study, the classification of Zaydī fuqahā’ that emerged in the mutaaḫḫirūn period of Zaydī fiqh and related terms are examined. The book named Bulūgh al-arab wa-kunūz al-dhahab fī-maʿrifat al-madhhab, which has great importance among the studies aiming to present the Zaydī fiqh accumulation as a uniform doctrinal structure was taken as a basis in the processing of the subject. After an introduction in which Zaydī fiqh studies are evaluated in their relationship with the subject, the issue is handled (...) under three main headings. In the first title, the author and his work are introduced, and in the second and third titles, the methods and terms used in the classification of the Zaydī fukahâ are examined. The author of the work is ʿAlī b. ʿAbd Allāh al-Shaharī (d. 1190/1776) who lived during the period of the Qāsimī dynasty (al-dawla al-Qāsimiyya) in Yemen. The most important feature of the work, which was prepared using many sources that were attributed importance among the Zaydī literature, is that it was the most comprehensive of all that had written on madhhab doctrine until then. The first part of the work explains that the right madhhab to be followed is Zaydiyya. In the second part, the classes of the Zaydī fuqahā’, which is the subject of our study, are explained. The fuqahā’ classes are primarily divided into two parts: al-salaf al-ṣāliḥīn and al-ḫalaf al-ṣāliḥīn. The first dates back to the beginning of the 3rd/10th century. This class is divided into two parts, as al-sābiqūn and al-mutaaḫḫirūn. The sābiqūn starts with ʿAlī b. Abī Ṭālib, his two sons al-Ḥasan and Ḥusayn and ends with the sons of twelve imams who are their descendants. Zayd b. ʿAlī (d. 122/740) is one of the twelve imams. The most important of the faqīhs in the part of mutaaḫḫirūn, which started with al-Qāsim b. Ibrāhīm al-Rassī (d. 246/860), are the six imams called ahl-al-nuṣūṣ or aʾimma al-nuṣūṣ. The reason why they are named as such is that their words were taken as a basis in determining the views of the sect on the field of uṣūl and furūʿ l-fiqh. al-Qāsim al-Rassī is at a point where all the knowledge of the Prophet's family and the principles agreed upon by sābiqūn, reach him through many channels. al-Hādī Yaḥyā b. al-Ḥusayn (d. 298/911), grandson of al-Qāsim, is the most important imam in terms of his position in the madhhab. The ḫalaf al-ṣāliḥīn is also divided into two parts as ahl l-taḥṣīl and ahl l-naẓar. The first part also referred to as muḥaṣṣilūn or aʾimma al-taḥṣīl, has no subcategories. The second part is divided into two sub-sections as ahl l-taqrīr and mudhākirūn. The muḥaṣṣilūn class starts with those who catch up with the last class of ahl al-nuṣūṣ and ends with ʿAbd Allāh b. Ḥamza (d. 614/1217), one of the three important imams. Two other important imams of muḥaṣṣilūn are Aḥmad b. al-Huṣayn (d. 411/1020) and his brother Yahyā b. al-Husayn (d. 424/1032). It is the fiqh activity of the jurists of this class, called taḥṣīl l-madhhab, that brought Zaydī fiqh, which was fiqh of imams (madhāhib l-aʾimma) in its first period, into a single madhhab and to its classical form in the last period. Mudhākirūn jurists lived at the same time as the ahl-t-taqrīr. This period is about 700 years from the beginning of the 6th/12th century, which is the last century of the muḥaṣṣilūn class, to the end of the 12th/18th century, when Shaharī lived. The roles of the ahl al-taqrīr in the madhhab mostly consist of reviewing the works of the ahl-l tahṣīl, approving the correct ones, and correcting the wrong ones. That's why they are so named. The author of Kitāb l-Azhār, Aḥmad b. Yaḥyā l-Murtaḍā (d. 840/1437), is one of the prominent jurists among the ahl l-taqrīr. The majority of Zaydi fuqahā’ belong to the muẕākirūn class. These are the lowest class of the ahl-al-naẓar. As an important result reached in the study, it is possible to express the following: There is a difference between some of the knowledge and opinions in modern Zaydī studies, which include the same subject as Shaharī's work, in terms of the classification of Zaydī fuqahā’ and the terms used. Therefore, the findings and conclusions based on this work should be confirmed by new studies on other Zaydī classics, and existing opinions on Zaydī jurisprudence should be reviewed. (shrink)

We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

Background: Treating medication-refractory freezing of gait in Parkinson’s disease remains challenging despite several trials reporting improvements in motor symptoms using subthalamic nucleus or globus pallidus internus deep brain stimulation. Pedunculopontine nucleus region DBS has been used for medication-refractory FoG, with mixed findings. FoG, as a paroxysmal phenomenon, provides an ideal framework for the possibility of closed-loop DBS.Methods: In this clinical trial, five subjects with medication-refractory FoG underwent bilateral GPi DBS implantation to address levodopa-responsive PD symptoms with open-loop stimulation. Additionally, PPN (...) DBS leads were implanted for CL-DBS to treat FoG. The primary outcome of the study was a 40% improvement in medication-refractory FoG in 60% of subjects at 6 months when “on” PPN CL-DBS. Secondary outcomes included device feasibility to gauge the recruitment potential of this four-lead DBS approach for a potentially larger clinical trial. Safety was judged based on adverse events and explantation rate.Findings: The feasibility of this approach was demonstrated as we recruited five subjects with both “on” and “off” medication freezing. The safety for this population of patients receiving four DBS leads was suboptimal and associated with a high explantation rate of 40%. The primary clinical outcome in three of the five subjects was achieved at 6 months. However, the group analysis of the primary clinical outcome did not reveal any benefit.Interpretation: This study of a human PPN CL-DBS trial in medication-refractory FoG showed feasibility in recruitment, suboptimal safety, and a heterogeneous clinical effect in FoG outcomes.

Self-injurious behavior is associated with diverse psychiatric conditions. Sometimes, SIB is the most dominant symptom, severely restricting the psychosocial functioning and quality of life of the patients and inhibiting appropriate patient care. In severe cases, it can lead to permanent physical injuries or even death. Primary therapy consists of medical treatment and if implementable, behavioral therapy. For patients with severe SIB refractory to conventional therapy, neuromodulation can be considered as a last recourse. In scientific literature, several successful lesioning and deep (...) brain stimulation targets have been described that can indicate a common underlying neuronal pathway. The objectives of this study were to evaluate the short- and long-term clinical outcome of patients with severe, therapy refractory SIB who underwent DBS with diverse underlying psychiatric disorders and to correlate these outcomes with the activated connectivity networks. We retrospectively analyzed 10 patients with SIB who underwent DBS surgery with diverse psychiatric conditions including autism spectrum disorder, organic personality disorder after hypoxic or traumatic brain injury or Tourette syndrome. DBS targets were chosen according to the underlying disorder, patients were either stimulated in the nucleus accumbens, amygdala, posterior hypothalamus, medial thalamus or ventrolateral thalamus. Clinical outcome was measured 6 months after surgery and at long-term follow-up after 10 or more years using the Early Rehabilitation Barthel index and time of restraint. Connectivity patterns were analyzed using normative connectome. Based on previous literature the orbitofrontal cortex, superior frontal gyrus, the anterior cingulate cortex, the amygdala and the hippocampus were chosen as regions of interest. This analysis showed a significant improvement in the functionality of the patients with DBS in the short- and long-term follow-up. Good clinical outcome correlated with higher connectivity to the amygdala and hippocampus. These findings may suggest a common pathway, which can be relevant when planning a surgical procedure in patients with SIB. (shrink)
