Authors: ÇAĞLAK Savaş
Published: June 2023

Climatic conditions play a decisive role in the realization of tourism activities. This study aims to determine the thermal comfort conditions of the Zigana Winter Tourism Center (ZWTC) for skiers (active skiers) and visitors (wanderers). The study used hourly measurement data from the meteorology station at ZWTC. Thermal comfort conditions were determined with WCI (Wind Chill Index) from simple indices and MPET (Modified Physiologically Equivalent Temperature) indices from complex indices. As a result of the study, cold, risky conditions for skiers from November to March in the period from the 10th day of January to the 10th day of February are effective, while other days can be expressed as comfortable. It has been determined that the hours between 10:00 and 16:00 during the day are suitable. There are cold risks throughout the entire period for visitors who do not do any activity. It is recommended to consider this study for tourism activities in ZWTC.
Understanding the why: The integration of trauma-informed care into speech and language therapy practice
Authors: O’ Leary Norma , Rupert Anna Claire , Lotty Maria
Published: June 2023

This article aims to highlight the need to integrate Trauma-Informed Care (TIC) into the practice of Speech and Language Therapy. TIC is a strength-based framework underpinned by an understanding and responsiveness to the widespread pervasiveness and impact of trauma. The literature on TIC within the field of Speech and Language Therapy is in its infancy but is progressing. In this context, there is an absence of clear guidelines for TIC in the field to support providers and administers to understand the relevance, underlying theory, and application to practice. In this paper we outline the theoretical underpinnings and application to practice. We argue that the profession requires an ongoing commitment to continuous research to corroborate communication-specific best practices of TIC to support clinicians in translating those findings into practice to best support clients.

Published: June 2023

The vascular structure and function are potentially useful biomarkers for tumor detection. Treatment with chemotherapeutic agents may impair vascular function and increase the risk of cardiovascular disease. This study aimed to use noninvasive pulse waveform measurements to identify differences in the frequency-domain indices of the pulse waveform in breast-cancer patients following anthracycline chemotherapy between with (Group KSY) and without (Group NKSY) receiving Kuan-Sin-Yin (KSY) treatment.

Radial blood pressure waveform (BPW) signals were measured noninvasively for 3 minutes in 31 patients, and the FACT-G, BFI-T, and EORTC QLQ-C30 questionnaires were administered. The following pulse indices were calculated for 10 harmonics: the amplitude proportion and its coefficient of variation, and the phase angle and its standard deviation.

The changes in spectral BPW indices were more prominent in Group NKSY than in Group KSY, especially for the decreases in BPW variability indices. Scores on the FACT-G, BFI-T, and EORTC QLQ-C30 questionnaires suggested that the quality of life following chemotherapy was better in Group KSY.

The identified decreases in pulse variability indices could be related to the greater impairment of regulatory activities in Group NKSY. The present findings may be meaningful in developing techniques with advantages such as being noninvasive and time-saving to evaluate the blood supply and physiological conditions following chemotherapy or other treatment strategies in cancer patients.

Published: June 2023

OBJECTIVE:

This study aims to analyze the performance of endorectal ultrasound (ERUS) combined with shear wave elastography (SWE) for rectal tumor staging.

METHODS:

Forty patients with rectal tumors who had surgery were enrolled. They underwent ERUS and SWE examinations before surgery. Pathological results were used as the gold standard for tumor staging. The stiffness values of the rectal tumor, peritumoral fat, distal normal intestinal wall, and distal perirectal fat were analyzed. The diagnostic accuracy of ERUS stage, tumor SWE stage, ERUS combined with tumor SWE stage, and ERUS combined with peritumoral fat SWE stage were compared and evaluated by receiver operating characteristic (ROC) curve to select the best staging index.

RESULTS:

From T1 to T3 stage, the maximum elasticity (Emax) of the rectal tumor increased gradually ( p < 0.05). The cut-off values of adenoma/T1 and T2, T2 and T3 tumors were 36.75 and 85.15kPa, respectively. The diagnostic coincidence rate of tumor SWE stage was higher than that of ERUS stage. Overall diagnostic accuracy of ERUS combined with peritumoral fat SWE Emax restaging was significantly higher than that of ERUS.

CONCLUSIONS:

ERUS combined with peritumoral fat SWE Emax for tumor restaging can effectively distinguish between stage T2 and T3 rectal tumors, which provides an effective imaging basis for clinical decisions.

Published: June 2023

OBJECTIVE:

To assess the potential use of plasma microRNAs (miRNAs) in diagnosis of acute venous thromboembolism (VTE).

METHODS:

Using BGISEQ-500 sequencing technology, we analyzed the miRNA profile of paired plasma samples from the acute and chronic phases of four patients with unprovoked VTE. Using real-time quantitative polymerase chain reaction (RT-qPCR), we verified nine upregulated named miRNAs in the acute phase in the plasma samples of 54 patients with acute VTE and 39 controls. We then compared the relative expression of the 9 candidate miRNAs between the acute VTE and control group, and plotted the receiver operating characteristic (ROC) curves of the differentially expressed miRNAs. We chose the miRNA with the greatest area under curve (AUC) to evaluate the effect of miRNA on coagulation and platelet function in the plasma samples of 5 healthy volunteers.

RESULTS:

The plasma levels of miR-374b-3p, miR-660-5p, miR-378a-3p, miR-425-5p, miR-3613-5p, miR-130b-3p, miR-183-5p, and miR-103b were higher in patients with acute VTE than in the controls, with AUCs of 0.6776, 0.6614, 0.6648, 0.6885, 0.8048, 0.6871, 0.7298, and 0.7498, respectively, and P values of 0.0036, 0.0081, 0.0069, 0.0020,<0.0001, 0.0022, 0.0002, and < 0.0001, respectively. There were no significant differences in miR-193b-5p level between the acute VTE group and the control group. Fibrinogen (Fib), thrombin– antithrombin complex (TAT), tissue plasminogen activator-inhibitor complex (t-PAIC), and TAT/plasmin-α2-plasmin inhibitor complex (PIC) were decreased in the miR-3613-5p group when compared with the control group ( P < 0.05) and the mean platelet aggregation rate was increased in the miR-3613 group ( P < 0.05).

CONCLUSION:

miRNAs can be potential biomarkers for diagnosing acute VTE, and miR-3613-5p may be involved in the formation, coagulation, and platelet functions in acute VTE.

Published: June 2023

The power metering system is an important part of the smart grid for data acquisition and analysis. The fault state of the main station directly affects the stable and safe operation of the power metering system. Hinged on the real-world data supplied by the monitoring platform of the Metrology Center of Guangdong Power Grid Co., Ltd., we present a novel malfunction diagnosis method for the main station of the power metering system. The proposed method utilizes the synthetic mi-nority over-sampling technique (SMOTE) and designs a combined model of long short-term memory (LSTM) network and ResNet. SMOTE solves the sample imbalance problem. Furthermore, the combined LSTM-ResNet model employs LSTM to extract the time-dependent signal feature and exploits ResNet to optimize data flow. Consequently, the proposed LSTM-ResNet model improves training efficiency and malfunction diagnosis accuracy. The proposed diagnosis mthod is verifird on the real-world data, which proves the proposed method’s surpass traditional methods. A specific analysis of results and the practical application of the proposed method is also elaborated.

Financial derivative features based integrated potential fishing zone (IPFZ) Future forecast
Authors: Vinston Raja R. , Ashok Kumar K.
Published: June 2023

In India, around 7 million people depend on fishing for their livelihoods. They are assisted with a reliable and fast brief forecast for the areas of fish aggregations. Habitat mapping is critical in supporting strategic choices on fish usage and protection. In conjunction with techniques for machine learning, remote control has made comprehensive fish mapping on relevant scales possible. In machine learning, supervised algorithms are utilized to make forecasts from datasets, when data is accessible without relating output factors. In this research work, Ocean Surface Temperature (OST) and Satellite derived Chlorophyl material are the basic inputs to generating the information of Potential Fishing Zone (PFZ). The 16 features and additional financial derivative features are used for accurate future prediction of PFZ. The unwanted and missing data are removed using effective pre-processing techniques. Among the various methods available for forecasting nonlinear phenomena, the Neural Network is the best and the efficient method to get a forecast. Therefore, the Function Fitting Neural Network (FFNN) technique is mainly used to predicting the Integrated Potential Fishing Zone (IPFZ). The practical analyses are performed by analysing the 80% -20%, 60% -40% and future data in terms of various parameters. From the results, it is proved that the suggested FFNN achieved 90% of accuracy, where the existing neural network achieved 86% of accuracy by implementing with financial derivative features for the 80% -20% of available dataset.
How to schedule the Volleyball Nations League
Authors: Lambers Roel , Rothuizen Laurent , Spieksma Frits C.R.
Published: June 2023

The Volleyball Nations League is the elite annual international competition within volleyball, with the sixteen best nations per gender contesting the trophy in a tournament that spans over 6 weeks. The first five weeks contain a single round robin tournament, where matches are played in different venues across the globe. As a consequence, each team follows an intensive travel plan, where it happens quite often that there is a large discrepancy between travel burdens of opposing teams. This is considered a disadvantage for the team that travelled more. We analyse this problem, and find that it is closely related to the well-known Social Golfer Problem: we name the resulting problem the Traveling Social Golfer Problem (TSGP). We propose a decomposition approach for the TSGP, leading to the so-called Venue Assignment Problem and the Nation Assignment Problem. We prove that a solution to the Venue Assignment problem determines the amount of unfairness, and we also prove that any solution of the Venue Assignment problem can be extended to a solution to the Nation Assignment problem satisfying the so-called home-venue property. Using integer programming methods, we find, for real-life instances, the fairest schedules with respect to the difference in travel distance.

Published: June 2023

The big data sources of National Statistical Offices (NSOs) are provided to make a superior platform for decision-making. The household income and expenditure survey is one of the economically important surveys especially when the inflation rate varies to assess the changes in households’ consumption patterns. In this case, big data can be beneficial and help to accurately measure consumption patterns of urban and rural households at every geographical level. This analysis is an exploratory study for the extraction of the size of injustice and imparity of household income and facilities implemented by classifying and clustering all Iranian households. Through this study, classification and soft clustering (Fuzzy clustering) techniques are employed to characterize the Iranian household types from 2011 to 2021, which are supervised and unsupervised approaches, respectively. Moreover, association rule mining techniques are employed to discover and extract consumption patterns for each cluster. Obtained results showed that there was a significant gap between purchasing power/receiving energy between lowest and highest income households from 2011 to 2021, and this gap is increasing day by day.

Authors: S Harsha , B Ismail
Published: June 2023

How to detect financial bubble? In response to this question, a vast amount of empirical research is devoted spanning almost half-century. However, identifying unambiguously the presence of a bubble in the financial time series remains an unsolved problem in standard econometric and financial economic approaches. In this paper, we study the impact of auto-correlated innovations, which is a most common feature of the financial time series, on recently developed unit root tests with varying lag to detect financial bubbles. We apply the more powerful test procedure to identify bubble on the quarterly observations of house price-rent ratios of 4 counties. The results of the study suggest that rolling Max Supremum Augmented Dickey-Fuller (MSADF) test as the best test procedure to detect financial bubbles in the future.

Published: June 2023

BACKGROUND: The clinical performance of medical devices is becoming increasingly important for the requirements of modern development processes and the associated regulations. However, the evidence for this performance can often only be obtained very late in the development process via clinical trials or studies. OBJECTIVE: The purpose of the presented work is to show that the simulation of bone-implant systems has advanced in various aspects, including cloud-based execution, Virtual Clinical Trials, and material modeling towards a point where and widespread utilization in healthcare for procedure planning and enhancing practices seems feasible. But this will only hold true if the virtual cohort data build from clinical Computer Tomography data are collected and analysed with care. METHODS: An overview of the principal steps necessary to perform Finite Element Method based structural mechanical simulations of bone-implant systems based on clinical imaging data is presented. Since these data form the baseline for virtual cohort construction, we present an enhancement method to make them more accurate and reliable. RESULTS: The findings of our work comprise the initial step towards a virtual cohort for the evaluation of proximal femur implants. In addition, results of our proposed enhancement methodology for clinical Computer Tomography data that demonstrate the necessity for the usage of multiple image reconstructions are presented. CONCLUSION: Simulation methodologies and pipelines nowadays are mature and have turnaround times that allow for a day-to-day use. However, small changes in the imaging and the preprocessing of data can have a significant impact on the obtaind results. Consequently, first steps towards virtual clinical trials, like collecting bone samples, are done, but the reliability of the input data remains subject to further research and development.

Published: June 2023

Zusammenfassung Zukünftig werden Raumfahrtmissionen (Langzeitflüge) zum Mond oder Mars durchgeführt werden. Langzeit- missionen gehen mit einem erhöhten medizinischen Risiko einher und die autarke Crew muss alleine und ohne Hilfe von außen Notfälle beherrschen. Atemwegsmanagement stellt hierbei eine Kernkompetenz für viele Notfälle dar. Bisher wurden 3 Studien (Originalarbeiten) durchgeführt, 2 davon während Parabelflügen und eine unter Wasser. Unter „free floating“-Bedingungen war die Erfolgsrate zur Insertion eines supraglotti- schen Atemwegshilfsmittels (SGA) hervorragend (91–97 %). Die Erfolgsrate einer konventionellen Laryngos- kopie war unter „free floating“-Bedingungen wesentlich schlechter und betrug 15–86 %. Für die Sicherung des Atemweges in Schwerelosigkeit z.B. im Rahmen einer Allgemeinanästhesie ist es essenziell, dass der Anwender ausreichend gut trainiert ist und der Patient im Optimalfall fixiert ist. Die Verwendung eines SGA scheint in Schwerelosigkeit wesentlich einfacher zu sein. Schlüsselwörter Atemwegsmanagement, Weltall, Luft- und Raumfahrtmedizin, Schwerelosigkeit, Anästhesie

A Systems Theory Analysis Of The Goshen Seventh-day Adventist Church's System Of Communication
Authors:   ,   Andrews University, Tucker Clavour
Published: June 2023

Problem The Seventh-day Adventist Church (SDA) is a complex and multilayered nonprofit organization (NPO), with carefully outlined policies and guidelines for almost every aspect of the organization. However, the philosophical or structural framework that guides communication within the organization is not clear. It is my hypothesis, having been a member and employee of the organization for almost 30 years, that not having such a structure has led to the creation of a fragmented culture of communication, which is observable in local congregations. This research assesses this phenomenon at the Goshen SDA Church, in Chicago, IL, and seeks to answer the following question: What is the system of communication at the Goshen SDA Church as perceived by the ministry and department leaders, based on the systems perspective of organizational communication? Purpose The purpose of this correlation study is to assess the current system of inter-departmental communication at the Goshen SDA Church, in light of the major tenets of the systems theory of organizational communication. The survey was designed to cover and collect data across five major sections, these are: (1) general information of the participants, (2) the independent nature of the ministries and departments, (3) the living or non-living nature of the churches’ system of communication, (4) the open or closed nature of the system of communication, and (5) the interdependence and connectedness of the ministries and departments. Method The data was collected using a self-administered, web-based survey hosted on SurveryMonkey.com, which also provided a detailed analysis of the collected responses. The data was then imported into SPSS, for further analysis with the aid of a data analyst, Laura Carrol, where association and regression tests were conducted. Descriptive statistics were then used to interpret the perceived reality of the leaders based on the recommendations of the theory. Conclusion The study confirmed my assumptions and revealed a significant breakdown in the system of communication, among the heads of departments, at the Goshen SDA Church. The data also revealed that though by nature the Goshen SDA Church is a living and open organism, the system of communication is more readily identifiable to that of non-living and closed systems. Other critical areas, such as interdependence, and connectedness were also perceived as poor among departments.
Faith and New Life in Christ: The Problem of Circumcision in Galatians 5:2-6
Authors:   ,   Andrews University, Paroschi Keldie
Published: June 2023

Problem Paul explicitly addresses the issue of circumcision for the first time in the epistle of Galatians in chapter 5:2–6. The precise meaning of circumcision, however, both historically and exegetically, has been much debated in Pauline scholarship. Method This thesis will first provide an overview of how circumcision has been interpreted in the context of different approaches to Pauline theology. Then, the historical background of the significance of circumcision around the first century AD will be analyzed, both in the Jewish and the Greco-Roman context. Finally, an exegetical study of Galatians 5:2–6 will focus on how Paul addresses the topic of circumcision in his theological discussion. Results When it comes to circumcision and the argument of Galatians, there is more involved than what has typically been emphasized by Pauline scholars. Historically, circumcision was also connected to the subjection of thoughts and passions to the will of God, as well as ideals of perfection and holiness. Exegetically, Paul opposes circumcision in Galatians 5:2–6 because it would jeopardize the maintenance of the believers’ ongoing experience of faith, i.e., sanctification. Conclusion Paul responds to the concern of maintaining one’s experience in Christ by writing that the Christian should be known by his or her total surrender to God by faith, a surrender to the sanctifying work of the Spirit that bears fruit in the life of the believer.

Problem The concept of spirituality has become popular in recent years among both Christians and non-Christians. The meaning of this term has evolved from biblical times to the present, and today we can come across many types of spirituality. Even in the Adventist Church this concept is understood differently. Ellen White emphasizes that we can correctly represent the character of Christ only by being spiritual, and unfortunately, there are a lot of people who are not spiritual. One of the most influential Adventist theologians concerned with this subject is Jon L. Dybdahl, which highlights the benefits of all types of spirituality. In the present study, we will identify the biblical vision of spirituality and compare it with Dybdahl’s theology of spirituality. Method To understand the biblical spirituality we will do an exegetical study of this term, analyzing the meaning of the word in Scripture and we will observe how its meaning has changed throughout history. We will also carefully examine Dybdahl’s theology of spirituality highlighting the premises, presuppositions and the methodology which Jon L. Dybdahl used in his study and also the implications that it has on developing Seventh-day Adventist spirituality. Results After the 17th century, the concept of spirituality began to be popular in Western Europe and then in many parts of the world. Today we can come across several types of spirituality and a variety of understandings of this concept. This research indicates that authentic spirituality is based on three principles/pillars that are (a) Solus Deus - The only God; (b) Sola Scriptura - Scripture alone; (c) Sola Fide - Faith alone. These principles are essential to reach Bible-sound spirituality, because it reveals that man does not have to let his culture, temper or personal preferences to influence his spirituality, but through faith in the Scripture and the influence of the Holy Spirit, the Subject (man) have to discover the Object (God) and become like Him. Conclusions This study indicates that Bible-based spirituality involves a strong relationship with the Triune God who is relived in Scriptures and a life continuously influenced and transformed by the Holy Spirit. Authentic Spirituality cannot be reached only by practicing certain rituals, but it implies both theoretical (hermeneutical/the knowledge about God) and practical (relationship/knowledge of God) side.
The Motif of the Messiah in Zechariah 9-14

Topic Zechariah 9-14 is full of prophecies regarding the coming of the messiah. The Jews at the time of Jesus awaited a messiah different from the one that came but how so? Did they misunderstand the prophecies or, by any chance, were the prophecies not clear enough? Purpose Firstly, it will be given an overview of the Book of Zechariah. Then, the messianic prophecies in Zechariah 9-14 will be examined closer and how they fit into the context of the prophets, the book of Zechariah, and the different chapters. An analysis of the similarities and differences will be written afterwards. Then Jewish expectation will be analysed. Afterwards, a conclusion will be drawn. Sources To have an in-depth study of the Texts of Zechariah, each messianic prophecy is translated with my own words from Hebrew into English. The context of the prophecies will be closer examined and the most recent and important commentaries will be considered. To understand the Jewish expectation of the messiah, Jewish literature and statements of Rabbis will be considered before a conclusion will be drawn. Conclusions The in-depth study of Zechariah showed that the messianic prophecies are in fact always in a military and judgment setting. However, it is not the messiah who acts belligerent, but it is the Lord who is fighting for his people. Zechariah shows that the messiah, was supposed to come as someone who restores the leadership and the nation, someone who restores the spiritual constitution. After this is accomplished, the restoration of the land will be the next goal. The Jews did not recognize their messiah because they did not anticipate forgiveness of their sins.

Problem Evaluations done at the West Central Brazil Union Mission office in 2015 found that the items related to proactive attitude and job satisfaction of the employees had the lowest score. Both the general evaluation and the self-evaluation revealed that creativity, conflict resolution, praises and rebuke, and self-development were the least developed items. It was assumed that the above described situation may reflect leadership practices and styles within UCOB. Method The study was conducted among 48 UCOB’s administrative office employees divided in three categories as described by the OLA research instrument (Top Leadership, Management and Work Force), which analyses the perception of the investigated population in six key areas of leadership, six levels of organizational health and job satisfaction. Results The study revealed that the participants perceived UCOB’s organizational health as Limited, the leadership style as Paternalistic Negative, and the level of job satisfaction as Good. Conclusion The research led to the conclusion that UCOB has two major priorities: develop servant leadership practices according to the OLA six key areas in order to attain Excellent and Optimal levels of Organizational Health; and develop leadership styles leading to Servant Leadership. As far as job satisfaction is concerned, considered as Good, there is always room for growth towards the level Very Good.
A Biblical Overview of the Concept of Fruit with an Emphasis on the "Fruit of the Spirit" in Galatians 5

Problem The topic of the Holy Spirit and especially the meaning of "being filled with the Spirit" is a relevant topic. Generally, it is thought to be related to miracles, healings, and explosive church growth among Adventists or to speaking in tongues and other manifestations, especially among Charismatic Christians. Few identify the fullness of the Spirit with holiness of character. In Paul, the presence of the Spirit in the life of the believer results in the presence of the "fruit of the Spirit" (Gal 5:22). Just like an apple tree produces apples, a person filled with the Spirit will produce the fruit of the Spirit. By understanding the nature of fruit, one can thus understand better what being filled with the Spirit entails. Method To that aim, this investigation focused on an inter-biblical thematic study of the word "fruit" with its corresponding Hebrew and Greek terms פְּרִי and καρπός. -- Results The results of this investigation were the following: (1) that fruit in the spiritual realm has to do with character traits and (2) to be filled with the Spirit has less to do with giftedness but more with holiness of character. Conclusions The concept of fruit is a major theme throughout the Bible. God is not only Creator and Provider of all fruits in nature but also in the spiritual realm where He additionally performs a cleansing work to increase the fruit. In the NT, where the concept of fruit is related mainly to the spiritual realm, it has to do with character traits and sanctification. This sanctification process is illustrated by the properties of the growing and maturing of the fruit. To be fruitful is not a goal in itself but has the purpose of glorifying the Father, to prove to be Jesus's disciples, to prepare the harvest for the Second Coming, and to determine one's true essential nature. In Gal 5 where Paul describes the "fruit of the Spirit," he uses four distinctive verbs to indicate how a fruitful Spirit-filled life can be obtained so that God’s holy character can be restored in the life of the person. While most Christians associate the work of the Spirit with supernatural exciting manifestations, it actually has to do with holiness of character. The work of the Holy Spirit during the latter rain is to prepare the character of God's people for the kingdom of God.
When Archaeology Interacted with the Bible: A Study of the Search for the City of Raamses of Exodus 1:11 in the Searcher's Socio Political Context

The purpose of this thesis is twofold. First, I will research what a selected group of authors and scholars has stated regarding their search for the biblical city of Raamses. 3 This step will involve research of the motive of those researchers who attempted to match Raamses of Exod 1:11 with geographical locations in Egypt, to follow their search within the social and political context of these scholars. Second, based on these scholars’ research, I will attempt to discover what happened when Bible and archaeology interacted in the search for the city of Raamses. The study begins with some pages of background. There, I have included a section covering the many geographical names we will encounter on this topic and their locations. Next, I provide a short introduction to archaeology and then follows the description of a selected group of scholars and their research. I have divided the study into fifty-year periods. The first three scholars covered, Gerardus Mercator, Edward Robinson, and Carl Richard Lepsius, published mainly before 1850. Then we will follow three other scholars, Frederick Charles Cook, Eduard Naville, and John William Dawson, who mainly published between 1850 and 1900, etc., until today. Since many of these scholars published also before and after the period in which they are considered in the present study, I have not followed these somewhat artificial divisions of fifty-year periods too rigidly but sometimes included what they have written later. I have chosen this approach in order to identify some of the major steps in the search for the city of Raamses as well as the development of the relationship between the Bible and archaeology. Each chapter includes a summary of the respective period regarding the views of archaeology for that time-period. Towards the end of the study, before the main conclusion, I include a final discussion about archaeology and the Bible. That chapter is based both on the scholars followed in this study but also on a wider context of what happened when archaeology interacted with the Bible.
Assessment of Eastern Massasauga Rattlesnakes (Sistrurus Catenatus) in Berrien County Historical Sites

The Eastern Massasauga rattlesnake (Sistrurus catenatus; EMR) is a small robust pit viper currently found in nine states and the province of Ontario, Canada. Wetland habitats have experienced significant destruction and fragmentation by humans; as a result, the current distribution of the EMR is a fraction of its historic distribution. For this reason, the EMR has been federally listed as threatened. In general, little is known about the current distribution of this rattlesnake (in the southwest corner of Michigan, the size of local populations or their stability and genetic diversity. Much of this knowledge is based upon historical data. My purpose was to update the available information on the current status in Berrien County and one Van Buren County site. This was done through presence/absence surveys, evaluation of potential threats at each site visited and genetic analysis at the haplotype level. Through my field surveys I confirmed presence of EMRs at 3 of the 5 historic locations surveyed. Current threats at these sites include human encroachment, road traffic, and general health of the particular habitat. Despite the relatively small sample size and isolated populations in these counties, the haplotype diversity discovered appears to be high in comparison to the rest of their range.
