Authors: Ragab Gamal H. , Bahgat Eman A.
Published: January 2019

This study reports about simple, robust and reproducible method for simultaneous bioanalytical determination of Valsartan (VAL) and co-administered Clopidogrel bisulfate (CGB) and Fenofibrate (FEN) in raw materials, spiked human plasma and tablets using isocratic RP-HPLC method. The chromatographic separation is carried out using isocratic binary mobile phase consisting of 80 mM phosphate buffer pH 3: Acetonitrile (30: 70 %; v/v) at the flow rate of 1.1 mL/min and 33 °C. A Diode array detector at wavelength 214 nm was used. Retention times for VAL, CGB and FEN were 3.1, 5.1 and 6.4 min, respectively. The calibration curves obtained were linear over the concentration ranges of 2.5 - 100 μg/mL for both VAL and CGB and 5 -100 μg/mL for FEN. The mean extraction recoveries of VAL, CGB and FEN from spiked plasma were 75.38±1.34 %, 89.91±2.17 % and 96.92±6.02 %, respectively. The limits of detection and quantification were 0.86, 0.67, 1.11 μg/mL and 2.60, 2.03, 3.36 μg/mL for VAL, CGB and FEN, respectively. The method was applied to the analysis of these drugs in spiked human plasma and in tablets as they are commonly used as a combination for prevention of stroke. Results obtained show good accuracy, precision and acceptable recoveries from plasma samples.

Published: January 2019

The present study investigates the application of induced air flotation (IAF) technique on PAHs (PAHs) removal performance from a real oilfield produced water of a separator cell. The quantification of total PAHs (PAHtot) was done using ultraviolet-visible spectrometry (UV-Vis) according to the naphthalene calibration curve. The UV-Vis spectra of naphthalene dissolved in a mixture of the binary solvent (water-ethanol) and the Tween 80 showed stability in the molecular orbital of C10H8. The use of small concentration of Tween 80 was revealed to be discrete in the quantification of PAHtot. The flotation process was improved at the critical micelle concentration of Tween 80 (CMC) of 2 % and the critical coalescence concentration of ethanol (CCC) of 0.5 mL/L for the PAHtot recovery of 49.76 % and the PAHtot content in the pulp of 50.24 %. At these concentrations, half of PAHtot was removed from produced water PW. Above the CMC and the CCC, the PAHtot recovery decreased and the PAHtot content in the pulp increased. It was found that there is a collector concentration at which the amount of water carrying from the pulp to the concentrate was increased and in parallel, the PAHtot recovery increased and the PAHtot content in the pulp decreased. Both of the CMC and the CCC have promoted the decrease on the conditioning time from 30 to 10 min and the flotation time from 20 to 6 min. Since the impeller speed and air flow rate were constant, the flotation of PAHs was limited. The flotation kinetics of PAHtot was described by the Higuchi model.

Authors: Tokárová Zita , Biathová Anna
Published: January 2019

Substituted thiophene-2-carbaldehydes 1a-dwere utilized in the synthesis of symmetrically substituted thiazolo[5,4-d]thiazoles 3a-d. Bis(5,4-d)thiazoles with thiophene core at the termini are the most employed in the chemistry of materials but exhibit insufficient solubility in majority of organic solvents with notable impact on the low yields of products. Accordingly, the synthetic approach towards 2,5-dithiophen- 2-yl-thiazolo[5,4-d]thiazole (3a) and its substituted derivatives 3b-d is discussed under the various reaction conditions. Appropriate structural characterisations are included with emphasis on relationship between structure and physicochemical properties highlighting the UV-Vis and fluorescence.
Studies on hydrometallurgical processes using nuclear techniques to be applied in copper industry. II. Application of radiotracers in copper leaching from flotation tailings
Authors: Rogowski Marcin , Smoliński Tomasz , Pyszynska Marta , Brykała Marcin , Chmielewski Andrzej G.
Published: January 2019

The use of radiotracers in the present study is intended to replace traditional steps of metal quantitative analysis (solution sampling and instrumental chemical analysis) and to allow real-time measurements of metal concentrations during the leaching process. In this study, 64Cu, an isotope of copper, was selected as a radiotracer. Samples of copper flotation tailings were irradiated in the Maria research reactor (Świerk, Poland) and mixed with an inactive portion of the milled fl otation waste. The leaching process was carried out in a glass reactor, and the radiation spectrum was measured using a gamma spectrometer. The material was then treated using various acids (sulphuric acid, nitric acid, acetic acid, citric acid, and ascorbic acid) in a wide range of their concentrations. Experiments with the radiotracer were conducted in sulphuric and nitric acids. The amount of the leached metal (copper) was calculated on the basis of the peak area ratio in the gamma-ray spectrum of the activated tailings and standard samples. Inductively coupled plasma mass spectrometry (ICP-MS) was also used to analyse the metal content. Maximum recovery of 56% Cu was achieved using 9 M HNO3, whereas the recovery was lowest for ascorbic acid (<1%). Both analytical methods were compared, and the results presented in this paper are in good agreement with radiometric measurements obtained using ICP-MS analysis.

Authors: Witkowska Anna , Rynkiewicz Tacjana Niksa
Published: January 2019

The article discusses the issue of designing a dynamic ship positioning system making use of the adaptive vectorial backstepping method and RBF type artificial neural networks. In the article, the backstepping controller is used to determine control laws and neural network weight adaptation laws. The artificial neural network is applied at each time instant to approximate nonlinear functions containing parametric uncertainties. The proposed control system does not require precise knowledge of the model of ship dynamics and external disturbances, it also eliminates the problem of analytical determination of the regression matrix when designing the control law with the aid of the adaptive backstepping procedure.

Authors: Kundakçi Burak , Nas Selçuk
Published: January 2019

Automatic Identification System (AIS) data is used for monitoring the movements of vessels live movements through instant transmission of vessel information while, at the same time, historical AIS data is used for marine traffic analysis by researchers. There are several methods and computer programs developed for the analysis of marine traffic by the use of AIS data. Combining the intersection algorithm proposed by Antonio (1992) and distance calculation method, this study develops a method to analyse vessel distribution on a selected cross sectional line (SCS) in the Northern Aegean Sea. As a complementary to the new methods proposed, a desktop application is developed in C# programming language to visualize the vessel distribution on the SCS line. SQL server is used for AIS data storage and analysis. The study is conducted over 7-day AIS data, specifically 2.382.469 rows and 42.884.442 data in total, belonging to the Northern Aegean Sea marine traffic. As a result, the mapping of the movements of different types of vessels in the Northern Aegean Sea is effectively performed and Frequency-Distance, Draught-Distance, SOG-Distance, SOG-COG distributions on the SCS line are successfully analysed by the new method introduced.
Simple Computational Methods in Predicting Limit Load of High-Strength Cold-Formed Sections due to Local Buckling: A Case Study
Authors: Bielski Paweł , Samson Leszek , Wysocki Oskar , Czyżewicz Jacek
Published: January 2019

Cold-formed thin-walled sections are prone to local buckling caused by residual stresses, geometrical imperfections and inconsistency of material properties. We present a real case of buckling failure and conduct a numerical and experimental study aimed to identify methods capable of predicting such failures. It is important because designers of structures are getting more FEA-oriented and tend to avoid lengthy procedures of cold-formed structures design. Currently adopted methods are complicated and require patience and caution from a designer which is reasonable in case of the most important structural members but not necessarily so in ordinary design. Since it is important, we offer an insight into several FEA and manual methods which were sufficient to predict the failure while remaining fairly simple. Using a non-uniform partial safety factor was still necessary. We hope that this paper will be of interest for people performing a lot of routine analyses and worrying about reliability of their computations.
Reliability Based Analysis and Design of a Tripod Offshore Wind Turbine Structure Assuring Serviceability Performance
Authors: Zhang Jianhua , Kang Won-Hee , Zhang Chunwei , Sun Ke
Published: January 2019

Typical tripod foundations are designed using deterministic computational models according to relevant standards and codes. However, for more cost-safety balanced design, uncertainties in significant parameters should be considered in preliminary design to ensure meeting a specific probabilistic safety target in the context of the complex configuration of a tripod structure. In this article, uncertainties associated with design parameters and modelling errors are considered using Monte Carlo simulations, in order to determine the key structural design parameters, and to determine the optimal balance between design parameters and design requirements. A Spearman rank-order correlation based analysis is carried out to understand the effects of design variables on maximum deformation, total weight, and natural frequency, and to have insight about important design parameters for improvement of a preliminary design. It is found that the tower diameter has the most significant effect on the maximum displacement on the hub as validated through engineering case studies. In addition, a statistical framework, which identifies influential design parameters and provides reliability evaluation, is proposed for the structural design of a tripod OWT system. The design cases considered in this study indicate that a simple deterministic design check cannot guarantee the required reliability level of the structure, and the cost-safety balance can be achieved by a reliability analysis with the consideration of the uncertainties in the structure.

Listing of Developer Companies as a Predictor of the Situation on the Residential Real Estate Market
Authors: Wolski Rafal
Published: January 2019

The stock exchange is considered one of the most important financial institutions in the market economy. The stock market reacts to the state of the economy almost immediately, and, in the end, the quotations of companies affect the state of other markets. The author decided to look at companies from the WIG Real Estate index as important entities shaping the real estate market. When comparing the situation on the capital market with the situation on the residential real estate market, one could, building an appropriate model, conclude how much these markets interact. Purpose - The purpose of the article is to present the links between two important markets, the capital market, with real estate companies as its representatives, and the secondary housing market. In order to achieve the goal, a research hypothesis was formulated: the economic situation on the real estate companies market will be reflected in the situation on the secondary housing market. Design/methodology/approach - Cross-sectional regression analysis was used in the study. Using the data from the Warsaw Stock Exchange and the National Bank of Poland, regression models where price changes in the secondary housing market are explained by the quotations of real estate companies and selected stock exchange indices were built. The study was carried out from the first quarter of 2011 to the third quarter of 2017. Findings - Two models were built in which the rates of return on investments in real estate companies explain the price changes in the secondary housing market in a statistically significant way. Thus, the research hypothesis was positively verified, showing that the real estate market and the stock market of real estate companies are interrelated. Originality/Value - The alternative method of analyzing the real estate market can be considered as the original value of the presented results. A demonstration of the connections between both markets allows us to validate the methods used on the stock market to analyze the real estate market. An example application is the use of methods for estimating the cost of capital from the stock market in the real estate market.
Price as a Measure of Market Value on the Real Estate Market
Authors: Gaca Radosław
Published: January 2019

Issues related to the relationship between prices and values of goods have occupied the minds of economists since the beginnings of economic thought. These considerations concern both general issues and the direct, practical dimension of values. For the real estate market, the main value category considered and used is market value. Its concept has been defined at different levels of legislation, but regardless of how detailed the content of the definitions, they all refer to price as the main basis for reasoning. On the other hand, a part of the economic trends call into question the possibility of measuring values directly on the basis of prices. Consequently, in the light of existing divergences in interpretation, can prices be a good yardstick for value, particularly in the light of the evolving concepts of Highest and Best Use (HaBU) and Hope Value? In an attempt to answer the question, the paper presents considerations on the relationship between prices and value on the real estate market, in particular in the context of the significance of this relationship for the determination of market value. Theoretical studies were supported by empirical research, which allowed for disproving the research hypothesis concerning the relations between the analyzed economic values.
Analysis of Prices in the Housing Market Using Mixed Models
Authors: Cichulska Aneta , Cellmer Radosław
Published: January 2019

Hedonic models, commonly applied for analyzing prices in the property market, do not always fulfil their role, mainly due to the application of simplified assumptions concerning the distribution of variables, the nature of relations or spatial heterogeneity. Classical regression models assumed that the variation of the explained variable (price) is explained by the effect of market features (fixed effects) and the residual component. The hierarchical structure of market data, both as regards market segments and the spatial division, suggests that statistical models of prices should also include random effects for selected subgroups of properties and interactions between variables. The mixed model provides an alternative for constructing various regression models for individual groups or for using binary variables within one model. With its appropriate structure, it makes it possible to take into account both the spatial heterogeneity and to examine the effects of individual features on prices within various property groups. It can also identify synergy effects. The article presents the issue of mixed modelling in the property market and an example of its application in a market of dwellings in Olsztyn. The research used transaction data from the price and value register, supplemented with spatial data. The obtained model was compared with classical regression models and geographically weighted regression. The study also covered the usefulness of mixed models in the mass evaluation of properties, and the possibility of using them in spatial analyses and for the development of property value maps.

Published: January 2019

Although most soft tissue tumors are benign, with a high healing rate after surgical excision, there is a variety of malignant tumors with differences in progression and prognosis. The study aimed to assess the survival rate in patients diagnosed with this pathology, based on the patient’s characteristics (age, gender, race), as well as the tumor’s histological type, differentiation degree, location and size. The retrospective study included a group of 103 patients diagnosed during 2010 and 2017 in our department. Considering the high healing rate of benign tumors, only the group of neoplastic patients (45 cases) was involved in the survival rate estimation, assessing tumor characteristics and individual comorbidities. Within this lot, we emphasized a predominance of neoplasm in patients aged over 50 years (32 cases), men (29 cases), and localization of the neoplasm in the thigh (23 cases). The predominant histopathological type, liposarcoma, was diagnosed in 67% of the cases, with dimensions over 6 cm and with local extension. There have been significant variations in mortality between the different histological subtypes (liposarcoma vs. synovial sarcoma). Local recurrences were showed in 18 cases of liposarcoma in the first 2 years after the surgical excision, with an increased aggressiveness of this neoplasm in men over 50 years. 12 cases developed distant metastasis, and until the end of the study, 7 deaths were reported in 3 cases involving associated comorbidities. The five-year survival is inversely proportional to the extent of the tumor and the local invasion, as well as to the age of the patient. An overall survival rate is difficult to appreciate in the context of a heterogeneous group of tumors so it must be evaluated for every histological subtype taking into account the patient’s particularities.

Published: January 2019

Ankle fractures are frequent and have a significant impact upon the function of the lower limb, as this joint has a crucial role in standing and especially in walking. Several classification systems have been developed concerning these fractures, connecting the traumatic mechanism to their treatment. Due to their character of articular fractures, functional restoration of local anatomy is necessary; therefore, surgery is mandatory in displaced fractures, affecting the congruency, the stability or the mobility of the ankle joint. The purpose of this paper is to describe the factors influencing the results of surgical treatment in these fractures, as it results from the experience of a level 1 Trauma Centre.

Two types of femoral neck fractures are nowadays identified: those resulting from low energy trauma, usually by direct by falling on the hip, in patients with affected bone stock (the so-called “fragility fractures”) and those produced by high energy trauma, even in younger people, with normal bone stock. These recommendations are addressed to the first category. for which impaired mineral bone density (MBD), osteopenia, and osteoporosis represent major enabling factors. These recommendations refer to classification-based local and general treatment of femoral neck fractures (excluding the basilar neck ones). The presumptive and definitive diagnoses include the precise description of the fracture pattern, by complete imagistic evaluation. The treatment depends on the type of the patient (demanding or non-demanding), on the type of the fracture (stable or unstable), as well as on the facility of early treatment, in certain cases. The main therapeutic goal in femoral neck fractures is early social and professional reinsertion of the patient, by gaining a status as close as possible to the one before the trauma; stable stabilization allowing early mobilization has a key role in fulfilling this objective Therefore, complete evaluation and monitoring of the patient by a multidisciplinary team is mandatory in order to perform a proper evaluation of the anaesthetic and surgical risk ( as these patients usually have pre-existing health problems, sometimes severe) , a safe and adapted (form the point of view of invasivity) surgery and an appropriate post-operative local and general treatment. Therefore, these recommendations have numerous connections with those involving the intervention of physicians from other specialities with whom orthopaedic surgeons must cooperate in these cases
Treading on tricky ground: reconstructive approaches to Charcot neuropathic arthropathy of the foot
Authors: Ion Daniela–Elena
Published: January 2019

Introduction and purpose:Charcot neuroarthropathy defines a cluster of progressive lesions affecting the joints and bones, as well as the soft tissues of the foot in the context of diabetes, a pivotal role being attributed to peripheral neuropathy. Loss of sensation and proprioception, subsequent repeated trauma, muscle and autonomic nervous system impairment contribute to the alteration of the foot’s architecture and distribution of pressure, ultimately triggering ulceration and gangrene. The urge to avoid amputation has fueled the development of conservative and reconstructive techniques capable of delaying, if not preventing such negative outcomes. The purpose of this review was to present the most frequently used reconstruction procedures and the challenges arising in adapting them to particular foot morphologies and lesion stages. Methods:Literature search was conducted using PubMed, resulting in around 90 articles, multicenter studies and reviews, 26 of which were considered most relevant in providing the guidelines for orthopedic reconstruction and postoperative care in Charcot foot patients with diabetic neuropathy prevailing over arteriopathy. Results:The tarsometatarsal and metatarsophalangeal joints are most frequently affected. Closed reduction, arthrodesis, and tendon lengthening are key features of an efficient correction, alternatively accompanied by resections and tenotomies. Ulceration and callus debridement may also be necessary, while prolonged casting and immobilization remain obligatory. Conclusions:Most authors agree that stabilizing the deformities, optimizing the pressure on the soft tissues, and promoting the healing of potential lesions are the main purposes of the interventions. Prompt recognition and correction of Charcot foot deformities improve life quality and minimize the prospects of amputation.
Developing Metacognitive Strategies of Future Teachers in the French System of Higher Education
Authors: Pliushch Valentyna
Published: January 2019

The article analyzes the trends in teacher education development with the aim to improve the system of education in Ukraine. The need to improve professional training of future teachers taking into account metacognitive learning strategies is emphasized. The main way of enhancing efficiency of professional knowledge acquisition is defined to be metacognitive processes. The study of psychopedagogical literature shows variety and diversity of scientific approaches to undestanding the essence of metacognitions. It is indicated that the implementation of metacognitive approach is impossible, unless the student possesses the knowledge of learning strategies. When the lecturer aims to develop them in the students, learning becomes more personality-oriented and the level of learner autonomy is increased and thinking is amplified. This, in turn, is one of the most important ways to develop self-study skills. Foreign educational science singles out three groups of learning strategies such as cognitive, socially affective and metacognitive (being the main element of educational actions). The methods of metacognitive learning in higher education institutions in France are analyzed. The metacognitive learning pattern of note-taking is defined as to be most practice-oriented. It consists of such stages as contextualization, decontextualization and recontextualization. The analysis of training programmes for future teachers proves that the implementation of metacognitive programmes into practice of higher teacher education in France is based on the following two processes: either their full assimilation with the already existing syllabi, or the expansion of syllabi with the specialized course of study in metacognitive learning. Therefore, these programmes urge lecturers to realize that under modern conditions it is necessary to switch to metalearning. Students are assisted in creating a list of competences and knowledge and are aware of the need to enhance them in the future. The analysis of metacognitive programmes for professional training of future teachers in France concludes that lecturers aim to develop future teachers’ ability to self-analyze and self-assess learning activities.

The article reveals the current status of the quality assurance development in the training process of the European Union (EU) border guard agencies. Besides, the study aims to describe the prospects for further quality assurance development of the border guards training in the EU countries. The views of scientists on the concepts of “quality assurance and control” and “quality of training” were critically studied. The quality of a border guard’s training was defined as a set of knowledge, skills and competencies of a border guard, including a border guard’s personal qualities, characteristics, which define a person as a specialist in the sphere of the state border protection and distinguishes him or her from other specialists and ensures success along the border guard career path. The study of the quality assurance system of border guards’ training in the EU countries revealed that it is conducted by the European policies and educational and training standards and promotes the formal certification and external accreditation of border guards’ training. It is indicated that the prospects for developing quality assurance mechanism for all-European border guard courses are connected with the possibility to provide external accreditation for such courses as: Introduction to Educational Technology and Training Delivery Methodology, which the author completed in 2017 and 2018. The process of accreditation is being conducted by an international quality assurance agency. The quality assurance system of the border guards training in EU is used in the Joint European Master’s Program in Strategic Border Management, developed by FRONTEX Agency in cooperation with European educational establishments. So, the State Border Guard Service of Ukraine can be particularly interested in this program, in order to facilitate the increasing of quality of Ukrainian border guards training.

The date 23 June 2016 brought in front of the United Kingdom and the European Union a very serious challenge named Brexit. In the June 23, 2016 referendum, the British voted to leave one of the most unique international organizations in the world, thus putting the EU in front of the UK’s request for the activation of Article 50 of the Lisbon Treaty, which the EU is facing for the first time. Brexit is opening new chapters in the history of the UK, while the EU is engaging with the procedures of the voluntary withdrawal of an important member state, which is known about its high political and military role in the world. Some experts of international relations and European studies say that Brexit will have much more consequences for the UK, some for the EU, but truth is that Brexit will be accompanied with many consequences for both of its protagonists. Its risks are very serious so they may result with the dissolution of the UK. Meanwhile, the increase of euroscepticism within the EU’s member states, with particular emphasis the presence of Eurosceptic voices in its most important members is at a very worrying level. Based on these facts, the knowledge about the real meaning of Brexit is necessary. Therefore, the main focus of this research lies in the classification of the main political consequences of Brexit for the UK and the EU.
Studies on Hexagonal Wire Mesh-Reinforced Crushed Stone Dust

Crushed Stone Dust (CSD), which is a waste product from an aggregate crusher, could be used as a pavement layer. To improve the tensile strength of CSD, it is worthwhile reinforcing it. In the present study an attempt has been made to reinforce a loosely and densely compacted CSD layer with Hexagonal Wire Mesh (HWM) placed in various positions. The results indicate that the California Bearing Ratio (CBR) value is improved by the placement of HWM in CSD. Field Rutting studies were also conducted on test tracks made of unreinforced and reinforced CSD layers. The rut depths were significantly reduced due to the inclusion of the reinforcement in the CSD layer.
Transparent Elemental Facade with an Integrated Ventilation Unit for a High-Rise Building – Development and Experimental Verification

Published: January 2019

The article documents the development of a modular transparent elemental facade. The cooperative development was realized in two areas, i.e., the development of facade ventilation units for an under-pressure ventilation system and experimental verification in a laboratory of a facade panel and optimization of its acoustic parameters. The task of controlled ventilation in modern residential buildings is to ensure the optimum quality of the interior environment and fulfill hygienic and thermal technical requirements that guarantee the comfort of the users. The paper discusses the development and experimental verification of atypical vertical ventilation units of an under-pressure controlled ventilation system for a residential high-rise building. A recommended concept for the facade´s details has been developed in relation to the ventilation system. Conceptual designs of alternatives to the air inlet openings of an under-pressure controlled ventilation system for the apartments with an atypical vertical geometry were proposed. An optimized alternative to air inlet openings in the bottom level of a vertical pilaster with the function of an air distribution channel for a ventilation system has been selected and developed. Laboratory experiments have verified the physical properties of the optimized alternative ventilation units of the under-pressure controlled ventilation system in their development cycle. The hydrodynamic regime of the air inlet openings of the controlled ventilation system has been verified by experimental research in a laboratory large rain chamber. The aerodynamic regime of a naturally controlled ventilation system was verified by experimental research in a large laboratory pressure chamber. The acoustic properties of the naturally controlled ventilation system were verified by experimental research in a laboratory´s acoustic chambers. The verified parameters of the ventilation units of the under-pressure controlled ventilation obtained by the experiment were compared with the design parameters. An experimental assessment of the mechanical, thermal and acoustical parameters of the elemental modular facade was carried out in a laboratory. At the end of the article, the results and conclusions of the laboratory experiment are summarized.
“A Promise to Support Us:” Undocumented Experiences on a Sanctuary Campus

This exploratory study examines the experiences of undocumented students at Hawthorne College, an elite, liberal arts institution with sanctuary status. Drawing primarily on a questionnaire and qualitative interviews, it considers 1) whether undocumented and Deferred Action for Childhood Arrivals (DACA) students on a sanctuary campus experience the characteristic psychosocial difficulties that mark the lives of undocumented students elsewhere and 2) the extent to which institutional policies mitigate these challenges. The research reveals that sanctuary is neither a panacea for undocumented students’ concerns nor is it a meaningless symbol. Students are protected from some typical barriers to college success, experience other barriers in classic ways, and face still other constraints quite differently in a privileged, high-pressure educational environment. The study adds to emerging research on the undocumented experience in higher education and offers preliminary insights into the promises and limits of the sanctuary campus movement.
Symbolic Sanctuary and Discursive Dissonance: Limitations of Policy and Practice to Support Undocumented Students at Hispanic Serving Institutions

An increase in public expressions of xenophobic and racist nativist sentiments followed the election of the 45th president of the United States, and higher education institutions across the country issued statements proclaiming their support for students impacted by changes to federal immigration policy. Guided by García’s (2017) organizational typology of HSIs and critical policy studies (Diem, Young, Welton, Mansfield & Lee, 2014), we conducted a content analysis of messages distributed via campus-wide email that addressed the vulnerabilities of DACA recipients and other immigrant students at two Hispanic-Serving Institutions in California. Our examination of these messages as policy documents reveals how campus and university-system leaders—even in a so-called “Sanctuary State”—attempt to create a notion of “campus as sanctuary” rather than committing to “sanctuary campus” policies and practices. We conclude with recommendations that push the notion of sanctuary campus beyond symbolic gestures and ask practitioners, scholars, and educators to reflect on the practices that foster true sanctuary environments.
