The existing research on testing Porter's hypothesis has not considered the selective bias in the sample when establishing a model. However, the selective bias is likely to cause instability of estimation results and reduce the reference value of conclusions. This article, based on individual enterprises in the China Industrial Enterprise Database, aims to verify the selective bias existing in previous research. Then, using the generalized propensity score matching method, a frontier method in the field of causal inference, we re-examined the causal relationship between environmental regulation and two types of technological innovation, weakened endogenous and reverse causal effects, and obtained a more complete and accurate dynamic impact of environmental regulation on the level of technological innovation for enterprises. The main conclusions of this paper are as follows: (1) The influence of environmental regulation on the level of process innovation has two dimensions: time and intensity, and the causal relationship between these dimensions changes from an N shape to an inversed-U shape over time. (2) The influence of environmental regulation on product innovation levels only includes the intensity dimension, and the two produce a U shape. (3) Process innovation and product innovation, to a certain extent, are reflected in the intriguing situation that they cannot gain and lose at the same time. (4) Light industries have a lower tolerance of environmental regulation than heavy industries, and they are more likely to be stimulated by environmental regulation. The conclusions of this paper can provide valuable advice to governments in relation to the formulation of environmental policies and laws.

The market for charitable donations has its own functional systems. Well-known charities prevail by seeking donations and the competition can be intense. This study examines the factors affecting consumers' concerns about charitable donations and willingness to continue to support
charities. Based on the results of this study, television and newspapers/magazines are major sources whence consumers gather charity information. The reputations of charities and the types of recipients are critical in gaining donors' trust to continue to support the organizations.
How well the charities are managed financially is less of a concern. Donation intentions can be increased if more relevant information is available to potential donors.

The current eye-tracking study explored the relative impact of object size and depth cues on 8-month-old infants' visual attention processes. A series of slides containing 3 objects of either different or same size were displayed on backgrounds with varying depth cues. The distribution of infants' first looks (a measure of initial attention switch) and infants' looking durations (a measure of sustained attention) at the objects were analyzed. Results revealed that the large objects captured infants' attention first, that is, most of the times infants directed their visual attention first to the largest object in the scene regardless of depth cues. For sustained attention, infants preferred maintaining their attention to the largest object also, but this occurred only when depth cues were present. These findings suggest that infants' initial attention response is driven mainly by object size, while infants' sustained attention is more the product of combined figure and background processing, where object sizes are perceived as a function of depth cues.

Abstract. Although tsunamis generated by submarine mass failure are
not as common as those induced by submarine earthquakes, sometimes the
generated tsunamis are higher than a seismic tsunami in the area close to
the tsunami source, and the forecast is much more difficult. In the present
study, reciprocal Green's functions (RGFs) are proposed as a useful tool in the
forecast of submarine landslide tsunamis. The forcing in the continuity
equation due to depth change in a landslide is represented by the temporal
derivative of the water depth. After a convolution with reciprocal
Green's function, the tsunami waveform can be obtained promptly. Thus,
various tsunami scenarios can be considered once a submarine landslide
happens, and a useful forecast can be formulated. When a submarine landslide
occurs, the various possibilities for tsunami generation can be analyzed
and a useful forecast can be devised.

Résumé Depuis plusieurs décennies, le rôle de la vision dans le développement de la préhension chez le bébé a été considéré comme crucial. Durant ces 15 dernières années, cependant, ce rôle a été remis en question par des travaux qui ont montré que les jeunes bébés sont capables de contacter les objets dans le noir et que, même dans des conditions de visibilité complète, ils utilisent principalement les informations proprioceptives pour diriger leur bras vers la cible. Quel est donc le rôle de la vision dans l'émergence de la préhension ? Dans cet article, nous présentons des données nouvelles sur le comportement d'exploration visuelle et d'atteinte d'objet d'une petite fille que nous avons suivie longitudinalement dès l'âge de 10 semaines. Afin de pouvoir élucider plus précisément comment elle a utilisé sa vision durant les quelques semaines qui ont précédé et suivi l'émergence de sa conduite de préhension, nous avons enregistré son comportement d'exploration visuelle d'objets au moyen d'un système d'enregistrement de mouvements oculaires ( eye-tracker ) et nous avons comparé sa performance à celle d'un groupe de bébés de 9 mois testés dans les mêmes conditions. Les résultats révèlent un changement du comportement visuel suite à l'émergence de la préhension. Ils suggèrent également que dès les premières semaines de préhension, vision et action interagissent dynamiquement pour créer une correspondance spatiale perceptivo-motrice de plus en plus précise.

Although public service employee promotive voice has recently attracted more attention from scholars, the link between negative public sector leadership (e.g., leadership ostracism) and employee promotive voice has not been fully explored in the extant literature. In a time-lagged study
of 226 public sector employee–leader pairs in China, we explored the mechanism behind leadership ostracism and employee promotive voice. We argued that public service motivation would have its dark side in the relationship between leadership ostracism and promotive voice; thus, we examined
the moderating effect of public service motivation in this setting. Results indicated that leadership ostracism had a significant negative impact on employees' promotive voice, and public service motivation positively moderated this relationship. The stronger the public service motivation
of ostracized employees, the weaker was their promotive voice. Theoretical and practical implications are discussed, and directions for future research are provided.
