Glutathione Protects Lactobacillus sanfranciscensis against Freeze-Thawing, Freeze-Drying, and Cold Treatment

ABSTRACT Lactobacillus sanfranciscensis DSM20451 cells containing glutathione (GSH) displayed significantly higher resistance against cold stress induced by freeze-drying, freeze-thawing, and 4°C cold treatment than those without GSH. Cells containing GSH were capable of maintaining their membrane structure intact when exposed to freeze-thawing. In addition, cells containing GSH showed a higher proportion of unsaturated fatty acids in cell membranes upon long-term cold treatment. Subsequent studies revealed that the protective role of GSH against cryodamage of the cell membrane is partly due to preventing peroxidation of membrane fatty acids and protecting Na+,K+-ATPase. Intracellular accumulation of GSH enhanced the survival and the biotechnological performance of L. sanfranciscensis, suggesting that the robustness of starters for sourdough fermentation can be improved by selecting GSH-accumulating strains. Moreover, the results of this study may represent a further example of mechanisms for stress responses in lactic acid bacteria.

The research method was done by using quantitative approach through survey method by collecting data through research instrument, and spreading questionnaire to the employee which the result then processed through SPSS program to know the influence between variables. The population in this study amounted to 103 people and a sample of 82 employees and lecturers who received additional duties as structural officials IAIN Kendari. Based on the results of this study, it is found that there is a direct positive effect of self-efficacy on IAIN Kendari organizational Citizenship Behavior (OCB) of 0.471 or self-efficacy had an effect on Organizational Citizenship Behavior (OCB) IAIN employees Kendari with 47.1%. Therefore, it is concluded that empowerment and self-efficacy have a direct positive and significant impact on IAIN Kendari Organizational Citizenship Behavior (OCB).
The effect of affect: How affective style determines attitudes towards the EU

Research shows that affective style (i.e. our individual ways of responding to emotions) matters for social behaviour. This article explores how affective style, as a new key predictor, explains attitudes towards the European Union, encompassing the feeling of internal efficacy towards the EU and trust in the EU. The study relies on survey data from Denmark (2014). The article concludes that the affective styles of tolerating, concealing and adjusting all significantly predict EU attitudes, albeit in different ways. Adjusting is positively associated with EU attitudes, while tolerating and concealing are negatively related to EU attitudes. Mediation analysis shows that most of personality's effect is not mediated by affective style. Hence, most of the effect of affective style is not merely a transmission of prior personality effect.
Boxy/peanut bulges, vertical buckling and galactic bars

Abstract Boxy/peanut bulges in disk galaxies have been associated to stellar bars. In this talk, we discuss the different properties of such bulges and their relation with the corresponding bar, using a very large sample of a few hundred numerical N-body simulations. We present and inter-compare various methods of measuring the boxy/peanut bulge properties, namely its strength, shape and possible asymmetry. Some of these methods can be applied to both simulations and observations. Our final goal is to get correlations that will allow us to obtain information on the boxy/peanut bulge for a galaxy viewed face-on as well as information on the bars of galaxies viewed edge-on.
Generalizing bounds on the minimum distance of cyclic codes using cyclic product codes

Two generalizations of the Hartmann-Tzeng (HT) bound on the minimum distance of q-ary cyclic codes are proposed. The first one is proven by embedding the given cyclic code into a cyclic product code. Furthermore, we show that unique decoding up to this bound is always possible and outline a quadratic-time syndrome-based error decoding algorithm. The second bound is stronger and the proof is more involved. Our technique of embedding the code into a cyclic product code can be applied to other bounds, too and therefore generalizes them.
Improving imbalanced scientific text classification using sampling strategies and dictionaries

Summary Many real applications have the imbalanced class distribution problem, where one of the classes is represented by a very small number of cases compared to the other classes. One of the systems affected are those related to the recovery and classification of scientific documentation. Sampling strategies such as Oversampling and Subsampling are popular in tackling the problem of class imbalance. In this work, we study their effects on three types of classifiers (Knn, SVM and Naive-Bayes) when they are applied to search on the PubMed scientific database. Another purpose of this paper is to study the use of dictionaries in the classification of biomedical texts. Experiments are conducted with three different dictionaries (BioCreative, NLPBA, and an ad-hoc subset of the UniProt database named Protein) using the mentioned classifiers and sampling strategies. Best results were obtained with NLPBA and Protein dictionaries and the SVM classifier using the Subsampling balancing technique. These results were compared with those ob- tained by other authors using the TREC Genomics 2005 public corpus.
Design Fiction Film-Making: A Pipeline for Communicating Experiences

The use of films in early stages of the design of technology is a practice that is becoming increasingly common. However, the focus of these films is usually centered on exploring the technology and its specifications rather than on the experiences that the technology can potentially create for its user. Previous research emphasises the relevance of experiences created by the technology in the users arguing that the emotions should be taken into account during early design stages and made part of the design itself. In this paper we provide a step-by-step production pipeline on how to make your own design fiction film, and how you can get the experiences across. For this purpose we focus on the experiences and emotions that a specific interaction medium elicits. We gained inspiration from the increased exploration of olfactory experiences in HCI. We used a classification of smell experiences as a starting point to produce a design fiction film for the automotive context, not limited by technology but inspired by experiences.
Automatic Identification of Bug-Introducing Changes

Bug-fixes are widely used for predicting bugs or finding risky parts of software. However, a bug-fix does not contain information about the change that initially introduced a bug. Such bug-introducing changes can help identify important properties of software bugs such as correlated factors or causalities. For example, they reveal which developers or what kinds of source code changes introduce more bugs. In contrast to bug-fixes that are relatively easy to obtain, the extraction of bug-introducing changes is challenging. In this paper, we present algorithms to automatically and accurately identify bug-introducing changes. We remove false positives and false negatives by using annotation graphs, by ignoring non-semantic source code changes, and outlier fixes. Additionally, we validated that the fixes we used are true fixes by a manual inspection. Altogether, our algorithms can remove about 38%~51% of false positives and 14%~15% of false negatives compared to the previous algorithm. Finally, we show applications of bug-introducing changes that demonstrate their value for research
Differentiated instruction for the teaching of english in the greek state school

Σύμφωνα με τις αρχές της διαφοροποιημένης εκπαίδευσης, ο δάσκαλος θα πρέπει να λαμβάνει υπόψη του τις ιδιαιτερότητες και τα ενδιαφέροντα των μαθητών του και να προσαρμόζει τη διδασκαλία του στις ανάγκες τους και στα μοναδικά χαρακτηριστικά τους. Η ολοένα αυξανόμενη διαφοροποίηση των μαθητικών πληθυσμών τα τελευταία χρόνια θα μπορούσε έτσι να αντιμετωπιστεί αποτελεσματικά, με σεβασμό προς τα ενδιαφέροντα, τις ανάγκες και τα ιδιαίτερα ταλέντα του κάθε μαθητή, μεγιστοποιώντας τις μαθησιακές ευκαιρίες για όλους. Η διερεύνηση των στάσεων των καθηγητών της Αγγλικής γλώσσας που εργάζονται στο Ελληνικό δημόσιο σχολείο απέναντι στη διαφοροποιημένη εκπαίδευση αποτελεί το στόχο της διατριβής αυτής. Επιπλέον, η διατριβή επιχειρεί να διακρίνει το βαθμό και τους τρόπους με τους οποίους η διαφοροποιημένη εκπαίδευση έχει επηρεάσει τη διδακτική πρακτική των καθηγητών στο Ελληνικό δημόσιο σχολείο. Η συλλογή ερευνητικών δεδομένων για την παρούσα διατριβή πραγματοποιήθηκε τόσο με ποιοτικές όσο και ποσοτικές μεθόδους. Αρχικά, διανεμήθηκε ερωτηματολόγιο με σκοπό να εκμαιεύσει τις αντιλήψεις των καθηγητών ως προς τη διαφοροποιημένη εκπαίδευση. Το ερωτηματολόγιο συμπληρώθηκε από 149 καθηγητές Αγγλικής σε δημόσια δημοτικά σχολεία στην περιοχή της Κεντρικής Μακεδονίας. Στη συνέχεια, πραγματοποιήθηκαν παρακολουθήσεις μαθημάτων δέκα καθηγητών Αγγλικής που εργάζονται σε δημόσια δημοτικά σχολεία της πόλης της Θεσσαλονίκης. Κατόπιν, οι δέκα αυτοί καθηγητές παραχώρησαν συνέντευξη με θέμα τις απόψεις τους σχετικά με τη διαφοροποιημένη εκπαίδευση και την εφαρμογή της στη σχολική τάξη. Τα ευρήματα υποδεικνύουν ότι οι καθηγητές Αγγλικής στην Α/βάθμια Εκπαίδευση έχουν πλήρη επίγνωση της ανομοιογένειας των μαθητικών πληθυσμών κι είναι θετικά διακείμενοι απέναντι στη διαφοροποιημένη εκπαίδευση. Επιπλέον, έχουν ενσωματώσει ορισμένες τεχνικές διαφοροποιημένης μάθησης στη διδασκαλία τους (π.χ. εργασία σε ζεύγη/ομάδες, κτλ.). Αντίθετα, άλλες στρατηγικές, ειδικά όσες απαιτούν περισσότερο χρόνο και προετοιμασία από τους διδάσκοντες, αποτελούν λιγότερο δημοφιλείς επιλογές (π.χ. παραγωγή διαφοροποιημένου υλικού για την αξιολόγηση των μαθητών, συμβόλαια μάθησης, κτλ.). Επίσης, τα ευρήματα δείχνουν ότι αρκετοί καθηγητές έχουν σχηματίσει ασαφή ή ανακριβή εικόνα των αρχών της διαφοροποιημένης εκπαίδευσης (π.χ. σε σχέση με το ρόλο του δασκάλου στη διαφοροποιημένη τάξη). Συμπερασματικά, μπορεί να ειπωθεί ότι η πλήρης εφαρμογή της διαφοροποιημένης εκπαίδευσης στο Ελληνικό δημόσιο σχολείο δεν έχει επιτευχθεί ακόμη. Επιπλέον, βρέθηκε ότι τα ιδιαίτερα χαρακτηριστικά των καθηγητών (π.χ. ηλικία, διδακτική εμπειρία, τυπικά προσόντα) επηρεάζουν σημαντικά τη στάση τους απέναντι στη διαφοροποιημένη εκπαίδευση και την επιλογή διαφοροποιημένων στρατηγικών. Οι παράγοντες αυτοί πρέπει να ληφθούν υπόψη στο σχεδιασμό κατάλληλων επιμορφωτικών προγραμμάτων πάνω στις αρχές και τις τεχνικές της διαφοροποιημένης εκπαίδευσης.
Clinical Instructors' Descriptions of Physical Therapist Student Professional Behaviors

Background and Purpose. Clinical instructors (CIs) have significant influence and responsibility guiding students toward professional competence through evaluation of clinical performance. CIs evaluate the professional behaviors of students in all three domains of learning: cognitive, psychomotor, and affective. The purposes of this study were to identify the behaviors that CIs expect, to describe appropriate and inappropriate behaviors, and to compare these behaviors to those cited in the literature. Subjects. Eleven physical therapists from a variety of clinical settings, with an average of 8.9 years of experience as CIs, were interviewed. Methods. Subjects agreed to a one‐time, audiotaped, individual interview. A pre‐interview form and a methodological journal maintained by the researcher were also used to gather data for this study. Open‐ended interview questions were used to identify the expected appropriate and observed inappropriate professional behaviors of students. The interviews were then transcribed. Interview transcripts were analyzed using qualitative methods for emergent themes and concepts. Results. Twenty‐four students demonstrating inappropriate behaviors were discussed during the course of the CI interviews. CIs supervised a range of one to six students with inappropriate behavior. These behaviors were divided into four concepts: An Attitude, Lack of Interest, Poor Communication, and Being Unprofessional. Appropriate behaviors were divided into concepts: Accepts Responsibility for Learning, Communication Skills, Empathy, and Professionalism. Discussion and Conclusion. The appropriate behaviors identified by these clinical instructors are similar to what has been reported in the physical therapy literature, with the exception of the expectation for empathy. The concepts of and behaviors related to inappropriate behaviors have not been cited in the physical therapy literature. Descriptions of these inappropriate behaviors or “Generic Inabilities” may be useful to academic faculty, CIs, and students, when examining and evaluating behaviors of students during clinical education experiences.
Development of a Resilience Fostering Program, and Its Effectiveness on Psychological Well-being in Adolescents with Externalizing and Internalizing Behavioral Disorders

Objective: This study examines the development of a resilience fostering program, and its effectiveness on psychological well-being in adolescents with externalizing and internalizing behavioral disorders. Method: In this developmental, and semiexperimental study, 58 adolescents (age mean = 12.77, SD = 0.88) participated. Neil & Dais’ Scale (2001), Achenbach’s Child Beha-vior Checklist (CBCL) Persian version(Minaei, 2004), Skehill’ General Well-being (2001), were respectively completed for resilience, behavioral disorders, and psychological well-being. Results: Covariance analysis revealed that the program could increase psychological well-being in the post test stage (P<.05), but not in the follow-up. On the other hand, resilience was enhanced and kept both in post-test and follow-up stages (P< .05). Conclusion: Accordingly, we can suggest that this program could improve psychological well-being, resilience, and behavioral disorders in some aspects.
Diffusive repair for the Ginzburg-Landau equation

We consider the Ginzburg-Landau equation for a complex scalar field in one dimension and show that small phase and amplitude perturbations of a stationary solution repair diffusively to converge to a stationary solution. Our methods explain the range of validity of the phase equation, and the coupling between the “fast” amplitude equation and the “slow” phase equation.
An Environment Monitoring System Architecture Based on Sensor Networks

This paper presents a an environment monitoring systems (EMS) architecture based on sensor networks, which includes a new adaptive clustering scheme and a multi-hop rout- ing algorithm, called sensors-enabled event routing architecture (SEERA). By monitoring the received signal power from other nodes, each node estimates the number of active nodes in real- time and computes its optimal probability of becoming a cluster head (CH) in order to minimize the amount of energy consumed in both intra- and inter-cluster communications. In order to prolong the network lifetime, the multi-hop routing algorithm is designed to be both energy-efficient and power-aware, based on the clustering architecture. The new clustering and routing algorithms scale well and converge fast for large-scale dynamic sensor networks, as shown by the simulation results.
Lie-algebras and linear operators with invariant subspaces

A general classification of linear differential and finite-difference operators possessing a finite-dimensional invariant subspace with a polynomial basis (the generalized Bochner problem) is given. The main result is that any operator with the above property must have a representation as a polynomial element of the universal enveloping algebra of some algebra of differential (difference) operators in finite-dimensional representation plus an operator annihilating the finite-dimensional invariant subspace. In low dimensions a classification is given by algebras $sl_2({\bold R})$ (for differential operators in ${\bold R}$) and $sl_2({\bold R})_q$ (for finite-difference operators in ${\bold R}$), $osp(2,2)$ (operators in one real and one Grassmann variable, or equivalently, $2 \times 2$ matrix operators in ${\bold R}$), $sl_3({\bold R})$, $sl_2({\bold R}) \oplus sl_2({\bold R})$ and $gl_2 ({\bold R}) \ltimes {\bold R}^{r+1}\ , r$ a natural number (operators in ${\bold R^2}$). A classification of linear operators possessing infinitely many finite-dimensional invariant subspaces with a basis in polynomials is presented. A connection to the recently-discovered quasi-exactly-solvable spectral problems is discussed.
A protected block device for Persistent Memory

Persistent Memory (PM) technologies, such as Phase Change Memory, STT-RAM, and memristors, are receiving increasingly high interest in academia and industry. PM provides many attractive features, such as DRAM-like speed and storage-like persistence. Yet, because it draws a blurry line between memory and storage, neither a memory- or storage-based model is a natural fit. Best integrating PM into existing systems has become challenging and is now a top priority for many. In this paper we share our initial approach to integrating PM into computer systems, with minimal impact to the core operating system. By adopting a hybrid storage model, all of our changes are confined to a block storage driver, called PMBD, which directly accesses PM attached to the memory bus and exposes a logical block I/O interface to users. We explore the design space by examining a variety of options to achieve performance, protection from stray writes, ordered persistence, and compatibility for legacy file systems and applications. All told, we find that by using a combination of existing OS mechanisms (per-core page table mappings, non-temporal store instructions, memory fences, and I/O barriers), we are able to achieve each of these goals with small performance overhead for both micro-benchmarks and real world applications (e.g., file server and database workloads). Our experience suggests that determining the right combination of existing platform and OS mechanisms is a non-trivial exercise. In this paper, we share both our failed and successful attempts. The final solution that we propose represents an evolution of our initial approach. We have also open-sourced our software prototype with all attempted design options to encourage further research in this area.
Evolution to the Edge of Chaos in Imitation Game

Motivated by the evolution of complex bird songs, an abstract imitation game is proposed to study the increase of dynamical complexity: Artificial "birds" display a "song" time series to each other, and those that imitate the other's song better win the game. With the introduction of population dynamics according to the score of the game and the mutation of parameters for the song dynamics, the dynamics is found to evolve towards the borderline between chaos and a periodic window, after punctuated equilibria. The importance of edge of chaos with topological chaos for complexity is stressed.
Convolutional coding and ARQ schemes for wireless communications

Flexible and low-complexity variable rate coding schemes based on rate-compatible convolutional codes are presented. The codes have a wide range of code rates and are optimized for good performance on both AWGN and Rayleigh fading channels. Furthermore, the application of these codes for rate matching, combined coding and spreading in a DS-CDMA system and hybrid type-II ARQ schemes are demonstrated. Very long constraint length convolutional codes with sequential decoding is proposed and shown to be suitable for high performance services in wireless systems.
My Colleagues Are My Friends: The Role of Facebook Contacts in Employee Identification

This study examined the extent to which having colleagues as friends on Facebook influences departmental and organizational identification by blurring the boundaries between work and private life. Based on social identity theory and proxy efficacy, we argue that work-related friends on Facebook may affect employee identification with different levels of the organization. The results of an online panel study among Dutch employees (N = 1,002) show that the perceived quality of online relationships with work-related Facebook contacts increases departmental identification, whereas the perceived authority of such contacts strengthens identification with the organization. Therefore, we suggest that blurring boundaries between work and private life through social media can have positive effects on organizational functioning.
Polarization and the Global Crisis of Democracy: Common Patterns, Dynamics, and Pernicious Consequences for Democratic Polities

This article argues that a common pattern and set of dynamics characterizes severe political and societal polarization in different contexts around the world, with pernicious consequences for democracy. Moving beyond the conventional conceptualization of polarization as ideological distance between political parties and candidates, we offer a conceptualization of polarization highlighting its inherently relational nature and its instrumental political use. Polarization is a process whereby the normal multiplicity of differences in a society increasingly align along a single dimension and people increasingly perceive and describe politics and society in terms of “Us” versus “Them. ” The politics and discourse of opposition and the social–psychological intergroup conflict dynamics produced by this alignment are a main source of the risks polarization generates for democracy, although we recognize that it can also produce opportunities for democracy. We argue that contemporary examples of polarization follow a frequent pattern whereby polarization is activated when major groups in society mobilize politically to achieve fundamental changes in structures, institutions, and power relations. Hence, newly constructed cleavages are appearing that underlie polarization and are not easily measured with the conventional Left–Right ideological scale. We identify three possible negative outcomes for democracy—“gridlock and careening,” “democratic erosion or collapse under new elites and dominant groups,” and “democratic erosion or collapse with old elites and dominant groups,” and one possible positive outcome—“reformed democracy. ” Drawing on literature in psychology and political science, the article posits a set of causal mechanisms linking polarization to harm to democracy and illustrates the common patterns and pernicious consequences for democracy in four country cases: varying warning signs of democratic erosion in Hungary and the United States, and growing authoritarianism in Turkey and Venezuela.
